Weather Highights of 2019

 

2019

 

JANUARY

1 - Very similar to 100 years ago, today's high of 58°, which occurred in the morning, was 39 degrees warmer than New Year's Day 2018, whereas 1919's high of 61° was 51 degrees warmer than New Year's Day 1918.  Today was the mildest reading on Jan. 1 since 2005.

6 - Today was the last day of an 18-day streak with above average temperatures in Central Park, the longest such streak in three years, since the record 34-day streak of Dec. 1, 2015 thru Jan. 3, 2016.  During these 18 days the high/low averaged 48/37, which was eight degrees above average.  The coldest temperature during the streak was 31°, which was reported tonight shortly before midnight.

18 - Although the half-inch of snow that fell before daybreak was of the "junk" variety (i.e., largely gone by the time I left for work), it was the first measurable snow in Central Park in nine weeks - since the "surprise" snowstorm of Nov. 15.  Only the winter of 2011-12 had a longer gap between its first and second snowfalls (12 weeks). 

19 - Today was the tenth day in a row with highs in the 30s, the longest such streak since the winter of 2011 when there were streaks of 11 days (Jan. 25-Feb. 4) and 12 days (Jan. 5-16).

20 - After a rainy morning (0.88" fell) Arctic air swept in, dropping the temperature from 42° late in the morning (the first reading in the 40s since 1/9) to 14° shortly before midnight.  This was the coldest reading in more than a year, since a low of 5° on Jan. 7, 2018.  Howling winds after dark produced wind chills around 0°. 

21 - This was one of the coldest days of the past 25 years, with a high/low of just 14/4.  Gusty winds raked the area throughout the day, producing wind chills in the -5° to -15° range.  And while there have been 12 days since 1994 with colder low temperatures than today's, only two had colder highs (10° on Jan. 19, 1994 and 13° on Jan. 6, 2018).  Today's frigid temperatures brought to mind very cold conditions that also fell on holidays in recent years (today was Martin Luther King Day): New Year's Day 2018, with a high/low of 19/7; Valentine's Day 2016, which had a high/low of 15/-1; and President's Day 2015, which had a high/low of 21/3.

24 - Rain began falling around daybreak and continued thru mid-afternoon, amounting to 1.33" (rain fell heaviest during lunchtime).  This was the sixth rainstorm of more than an inch in the past six weeks.  During this period more than nine inches of rain fell.  In addition to the rain, today experienced very mild temperatures as the high rose to 59° late in the morning (but fell to the mid-30s by midnight).  This came just three days after a low of 4°.  Today was also the first day since 1/9 not to have a low of 32° or colder.

30 - The ferocious cold that descended upon the Midwest, Great Lakes region and Ohio Valley over the past few days made its way east, ushered in by a snow squall mid-afternoon.  Once the front passed thru, the temperature dropped from the low 30s to the single digits by 9PM (and down to 6° by midnight).  Howling winds produced sub-zero wind chills.  The 0.4" of snow that fell during the 15-minute squall brought the month's total snowfall to 1.1", keeping January from joining thirteen others that had less than an inch of snow.  

31 - Today's frigid high/low of 16°/2° was quite a contrast to the first day of the month (aka New Year's Day), which had a mild high/low of 58°/39°.  Today's low was the coldest reading thus far this year (and since Feb. 2016), but its mean temperature tied that of Jan. 21, with a high/low of 14°/4°, for coldest (only four other days in the past 25 years have had colder mean temperatures).  Finally, the day's high temperature tied 1935 for the coldest high on this date.

 

FEBRUARY

4 - After two days in January came very close to 60° (highs of 58° and 59°), today had the year's first high in the 60s (61°).  This came just four days after a low of +2°, the fewest number of days between a reading colder than 10° and a high of 60°+ since January 1986, when there was a three-day gap (low of 8° on 1/15 followed three days later by a high of 63°) - but this year's jump in temperature was greater.  This was the second huge swing in temperature in the past week-and-a-half as the temperature rose from 4° to 59° between 1/21 and 1/24. 

12 - Light snow began falling shortly before 9 AM, then mixed with sleet a few hours later before turning mostly to sleet in the afternoon before changing to a mix of snow and rain by evening.  The snow/sleet accumulated 1.2", the first accumulation of an inch or more in three months (since the "surprise" snowstorm of Nov. 15).  During the first few hours of snow the temperature dropped from 30° to 26°, then slowly rebounded, and was above freezing by 6:00 PM.  

 

MARCH

4 - Snow that accumulated two inches yesterday evening continued overnight, adding three more inches.  (For the entirety of the storm the temperature was above 32°.)  These were the fourth and fifth days in a row with measurable snow, just the third time this has happened, joining streaks during the winters of 1923 and 1938.  This snowfall also brought March's snowfall to 10.4", more than the 10.1" that fell in the preceding four months.

7 - Today, with a high/low of 32°/18°, was the third day in a row with a high of 32° or colder.  The average high/low during these days was 30°/19°, fifteen degrees colder than average.  This was the first cold streak of three or more days in March since 1984, and just the tenth since 1900.  (It was also the longest such streak this winter.)  Despite the cold temperatures no measurable snow fell during these three days. 

15 - Despite lightly overcast skies the temperature rose into the 70s for the first time this year.  Although this was about three weeks later than the previous two years first 70s (Feb. 24 in 2017, Feb. 21 last year) it was still nine days ahead of schedule.  Today's high reached 75°, which was the warmest reading since 10/11.  (The following day the afternoon temperature was twenty-five degrees colder, down to what it should be in mid-March.) 

21-22 - Like last year on the first full day of spring, a coastal storm impacted the area but this time it was an all-rain event (8.4" of snow fell from last year's storm).  Rain began at daybreak yesterday and continued until late this morning.  In total 1.43" fell, with about two-thirds of that amount falling last night through the pre-dawn hours of today (0.75" was measured yesterday, 0.68" today).  This was the biggest rainstorm so far this year.  Besides the rain, gusty winds also raked the area, with peak gusts of 35-45 mph.

24 - Following the coastal storm of 3/21-22, the humidity fell significantly, bottoming out at 18% yesterday evening and down even further today, dropping to 13% at 2 PM (average reading in the afternoon during March is around 50%).  This was the lowest humidity level since May 2 of last year, when it dropped to 12% (the lowest reading in the years since 2000 is 6%, on March 30, 2007).

26 - Two days after the humidity dropped to Arizona-like levels during the afternoon, it dropped nearly as low today, bottoming out at 14% around 4:00 PM.  This was the fourth day in a row to report humidity levels under 20% at some point during the day.  During the course of a March day the humidity averages in the mid-50s, but today and on 3/24 it averaged 21%.

28 -Temperatures were seasonable for the Yankees' earliest home opener, but sitting outdoors when it's in the low-50s is more what you'd expect for a football game.  Skies were sunny but then turned lightly overcast after the game against Baltimore ended (which the Yankees won 7-2).  

 

APRIL

6 - After yesterday's raw, drizzly and cold conditions, with afternoon temperatures hovering around 40°, a big rebound took place today as skies were sunny and the high reached 68°.  Then two days later the reverse happened as the temperature fell into the upper 40s around midnight after the temperature was in the upper 70s earlier that evening (peaking at 79° shortly after 4:00 PM), the result of winds shifting from the west to the northeast.

19 - Great weather on Good Friday, as the high reached 80° - the first day in the 80s this year (it came close on 4/8 when the high reached 79°).  And although this was a few days earlier than the average date of the "first 80" (4/22), only one other year in the 2010s had it occur at a later date (in 2014, on 5/10).

30 - Today was the eighteenth day this month with measurable precipitation, the most of any month since May 2012, and the most on record of any April (the most for any month is 20 days, in July 1871 and May 1888).  However, despite this high frequency of rainy days the amount that fell, 4.55", was just an average amount.  (Seven days had 0.03" or less.)  By contrast, New York's ten rainiest Aprils averaged 12 days of precipitation (ranging from nine to fifteen).

 

MAY

4 - Today's high of 71° came one year after 5/4's morning low was 72°.

5 - It was a rainy and chilly day with 1.31" measured and PM temperatures only in the low 50s (most of the rain fell in the morning and after dark).  This was the tenth day of the past eleven with measurable rain, a period in which 2.67" of rain fell (today, the rainiest of these days, accounted for nearly half of the total).  It was also the twenty-second day of the past thirty-one with rain (today was the rainiest of these twenty-two days as well).

12 - A nor'easter brought a cold, all-day rain on Mother's Day.  Temperatures fell throughout the day, from the upper 50s just after midnight to the 40s by daybreak, where they stayed for the rest of the day (bottoming out at 43° as midnight approached, the chilliest reading on Mother's Day in the years since 1980).  This was just the second Mother's Day to have temperatures in the 40s for the entire afternoon (the other, in 1924, had temperatures in the 40s for the entire day).  And with 1.32" of rain measured, this was just the fifth time an inch or more of rain fell on Mother's Day (one of those five, in 1946, was also on 5/12).

13 - It was rainy and unusually chilly with temperatures staying in the 40s for the entire day, continuing a streak of hours with sub-50° readings that began at dawn yesterday; today's high/low of 48°/42° was seventeen degrees below average (the low was the chilliest in May in six years).  Much of the 0.70" of rain that fell today was during the afternoon/early evening.

14 - Including today, which had afternoon and evening showers, 70% of the past 40 days reported measurable rainfall in Central Park, twice as many days as the typical number (28 vs. 14).  However, just seven of these days accounted for about three-fourths of the of the 8.55" of rain measured in this period.  During lunchtime today the temperature rose out of the 40s for the first time since daybreak on 5/12, a span of 56 hours.  Then after just a few hours in the 50s the temperature once again dipped below 50°.

17 - Rain fell for the eighth in day a row, the longest rainy streak since another one of eight days in the summer of 2006 (and the thirteenth eight-day streak since 1900).  The rain that fell was minimal, 0.03", and came from light showers during lunchtime and between 9:30-10:00 tonight.  This was also the seventh Friday in a row with rain, and the ninth of the past ten (the one Friday with no measurable rain reported a trace).  In total 2.56" of rain fell during this streak.  Today's high of 76° was the mildest reading during the streak.

20 - One month after the year's first 80-degree day (on 4/19), today had the second high temperature in the 80s.  And at 85° today's high was the warmest in more than eight months (when it was 93° on 9/5).  

25-27 - Both Saturday and Sunday of Memorial Day weekend had sunny skies through mid-afternoon, then clouds gathered; Sunday's clouds produced heavy showers between 5:30-6:30 (0.20" was measured).  Before Sunday's clouds and showers the day had the warmest reading of the year so far; its high of 86° was fifteen degrees warmer than Saturday's.  Memorial Day had optimal conditions, with wall-to-wall sunshine, comfortable humidity and a high of 80°.  (This was the first time this year to have back-to-back days with highs in the 80s.)

30 - Today was the 19th day this month with measurable rain in Central Park, tying May 1973 and Dec. 1972 for the second most days of precipitation of any month.  (The most, 20 days, occurred twice in the 19th century - in July 1871 and May 1888).  Like yesterday, which reported 0.80" of rain, much of today's 0.95" poured down during the evening commute.  This month's excessive number of rainy days followed April's 18 days (the most on record for April); however, May's rainfall was more than two inches greater (6.82" vs. 4.55") - and it was more than what fell in July 1871, May 1888, May 1973 and Dec. 1972.

 

JUNE

2 - A nighttime thunderstorm dumped 0.78" of rain in the 30 minutes between 9:45 and 10:15.  This was the greatest amount in such a brief period so far this year.  Central Park appeared to be the bulls-eye for the heaviest rain as Newark Airport reported 0.31", LaGuardia had 0.30" and JFK just 0.03".  And at Yankee Stadium there was no rain delay in a game that ended at 10:37.      

25 - Shortly after daybreak a deluge dumped 0.86" of rain in a little less than an hour.  This tied 6/2 as the rainiest day this June.  And although the rest of the day was rain-free it was very humid, with dew points in the low 70s during much of the afternoon (this was the first day I used my a/c).  Additionally, today had the first low in the 70s of the year, about three weeks later than typical and the latest date in ten years.  (The City was still waiting for its first reading in the 90s.)

29 - After 6/27 and 6/28 got very close with highs of 89°, today's high of 91° was the first in the 90s this year - five weeks later than the average date for this occurrence and the fifth latest first-90 in the years since 1970 (the other four years were 1972, 1982, 1985 and 2014).

30 - Conditions for the 50th Gay Pride Parade were very nice through early afternoon, with the temperature rising into the low 80s, but then a quick shower interrupted the parade mid-afternoon.  And although it lasted for only 15-20 minutes the 0.06" that fell was the first measurable rain during the parade in 11 years (heavier amounts fell over Long Island).  This shower was also accompanied by winds that gusted to 37 mph at Central Park.  

 

JULY

4 - Today's high reached 90°, the first time in the 90s on the 4th of July in seven years.  Skies were mostly clear but the heat was tempered somewhat by reasonable levels of humidity.

6 - Uncomfortably high humidity (the dew point for much of the day was in the 72°-74° range) made the high temperature of 90° feel like 99°.  But despite these oppressive conditions, strong thunderstorms over NY State, central/eastern PA and northern NJ that appeared to be aiming for the City from mid-afternoon onward, all dissipated, producing only some passing sprinkles but no measurable rainfall.  Today was the 14th day in a row with highs of 83° or warmer, the longest such streak since one of 17 days in August 2016.

17 - A severe thunderstorm between 8-9:00 PM dumped more rain (1.14") than what fell in the previous three weeks (0.99").  Earlier in the day sauna-like conditions prevailed as the dew point reached the mid-70s, the temperature rose to 93° and the heat index reached 105°.  It also appeared today would be one of those rare summer days with a low of 80°+, but when tonight's storm moved in the temperature dropped to 73°.  Rain continued after the initial storm, adding an additional 0.68", making this the wettest day of the year.  This moisture was from the remnants of what was hurricane Barry, which had flooded Louisiana earlier in the week.  This was the second tropical storm named Barry to drench New York; the first visit was in June 2007, when nearly four inches of rain fell.    

21 - Today's high of 95° matched yesterday's, and both days had lows in the 80s (82° yesterday, 80° today).  The dew point peaked at 77° today during mid-afternoon; it was the highest so far this summer and produced a heat index of 107°.  This was the fifth day of the past six to have highs in the 90s.  The outlier was 7/18, which had temperatures stuck in the 70s all day due to afternoon winds that were out of the northeast.

22 - Shortly before Monday's evening rush hour was about to get underway three rounds of strong thunderstorms brought heavy rain, with 1.66" measured by midnight (most of it fell between 3:45 and 7:30 PM).  The storms erupted shortly after the dew point rose to an absurdly high 79°.  Today's downpours (and more rain would fall the following morning) came less than a week after the remnants of hurricane Barry produced 2.33" on 7/17-18.  Before the storms arrived the temperature had reached 90°, extending the heat wave to four days.

23 - After yesterday evening's deluge another period of rain that ended shortly after daybreak brought an additional 0.53".  This evening/morning rain event produced 2.19", which was similar in amount to the one that soaked the City on 7/17-18 (2.33").  What made them different, however, is that last week's was from the remnants of tropical system Barry while yesterday and today's was produced by a cooler air mass moving into the area.  The combined amount of these two big rain producers was comparable to a month's worth of rain and followed a three-week period that had less than an inch of rain (6/26-7/16).  After a four-day heat wave, today's high was a refreshing 74°, ten degrees below average and the coolest high in five weeks.

 

AUGUST

13 - Significant rainfall of one to two inches predicted for the afternoon and evening failed to materialize as just 0.07" fell in the morning.  (If this had been a snowstorm that was a bust, forecasters would have been lambasted by snow lovers, but rainstorms that don't deliver fail to spark outrage.)  Overcast skies kept the temperature in the 70s all day for the third time this summer; all three days had a high/low of 79/71.  

22 - Today, with a high of 90°, was the sixth day in a row with a high of 87° or hotter, the longest such streak since another one of six days in August 2016 (8/11-16).  However, the streak in 2016 was 3.5 degrees hotter (average high of 92.2° vs. 88.7°).  Shortly after sundown the approach of cooler air triggered strong thunderstorms that dropped 1.02" of rain between 8:30 PM and 1:00 AM.  (I was at a work-related cocktail party at a rooftop bar that, fortunately, ended shortly after 8:00.)

29 - The previous six days had been five degrees cooler than average (high/low of 75°/64°), which followed six days in a row that were five degrees warmer than average (89°/73°).  And today was "just right", with temperatures at seasonable levels (81°/66°).

 

SEPTEMBER

2 - Although it was a modest amount, the 0.30" of rain that fell during showers between 10:45 AM and 3:00 PM was the most to fall on Labor Day since 2003 (more than an inch of rain fell at Newark Airport).  Conditions rebounded somewhat once the showers moved out but dew points in the low 70s made it a bit uncomfortable.  However, the temperature got no higher than 74°, which was the coolest high on Labor Day in ten years (when it was also 74°).

6 - The northernmost bands of showers from hurricane Dorian moved through the area during the afternoon and early evening, with most of the minimal rainfall pouring down between 3-4:00 PM (0.27" was measured).  With the storm situated to the south-southeast of the metro area winds were from the east-northeast (peak gust in Central Park was 29 mph), making it unseasonably cool.  Before the rain moved in at lunchtime the mercury peaked at 67° then dropped to 58° by evening.  This was the first time since mid-June that a high and low were in the 60s/50s. 

19 - Humidity of 15% or lower occurs very infrequently in New York, and when it has happened it's been in March and April (in the years since 2000) - until today, when it dropped to 15% for a few hours this afternoon.  The last time the humidity was this low in September was on Sept. 11, 2001, when it bottomed out at 16%.

 

OCTOBER

2 - For the first time since 1941 the temperature soared into the 90s in October.  Today's high of 93° broke the record set in 1927 (which was October's first 90-degree reading).  This was a 12-degree jump from yesterday's high, which was already 12 degrees warmer than average, and the first 90-degree reading in six weeks (8/22), making it the fifteenth this year (below the average of 18).

3 - The day after the mercury soared to 93° (twenty-four degrees above average) winds shifted overnight to a northeasterly direction and temperatures this afternoon were only in the mid-50s.  Light showers and drizzle that fell throughout the day amounted to 0.34" - the largest daily rainfall in six weeks.

5 - It was a clear and brisk day with a high/low of 61°/45°.  This was the first low in the 40s this fall - and the chilliest first-40 since 2003 and 2002 (both at 44°).  Today's low came less than 72 hours after a sizzling high of 93°.  And while this was certainly quite a transition, there have been eight years in which the first low in the 40s came before the final-90 (the most recent being in 1961).

6 - Although it was just 0.01", this was the first measurable rainfall on this date since 2001.  It occurred in the evening at around 7:00.

10 - A year ago on this date the low temperature was 71°, which was the latest date for a low in the 70s.  This year, the high was the same reading.  And while it was quite a contrast from last year the high was still five degrees above average.    

16 - A nor'easter lashed the area from mid-afternoon until about 11:00 PM, dumping 1.83" of rain; howling winds gusted between 30-40 mph at Central Park (and 50-60 mph gusts were clocked elsewhere).  Today's rainfall was greater than the amount that fell in the previous six weeks.  It was also the biggest daily rainfall of the year, besting 7/17's amount by 0.01".  However, this wasn't the year's greatest storm total as two storm systems in July, each encompassing two calendar dates, dropped more than two inches (2.33" on 7/17-18 and 2.19" on 7/22-23).

26 - Although it was just 0.01" this was the first measurable rain to fall on this date since 2007.

27 - For the third time in the past four years more than an inch of rain fell on this date.  This year it amounted to 1.38"; in 2018 1.27" was measured and in 2016 1.41" fell.  Most of this year's rain fell between 10 AM and 1 PM.

31 - It was a very mild day, with the warmest readings occurring after dark.  The day's high of 71°  didn't occur until close to midnight.  This was the mildest reading since 10/14 and the mildest reading on Halloween in ten years (another high of 71°).  Besides it being so mild (the low was 60°) the day was also uncomfortably humid, with the dew point in the mid-60s and humidity in the 85-90% range.  Luckily for trick-or-treaters, showers that produced 0.54" of rain were over by noon.  (Also, a strong cold front that triggered some violent storms didn't reach the City until after midnight.) 

 

NOVEMBER

8 - The first temperature of 32° or colder this season occurred tonight.  This was nearly two weeks earlier than the usual date for this occurrence.  Just before midnight the temperature dropped to 29°, which tied the record from 1886.  (The next day's low of 27°, however, wouldn't be a record.) 

12 - A widespread, and early, Arctic outbreak passed through the area shortly after daybreak, dropping the temperature from 57° to 25° just before midnight.  This cold reading was a record low for the date.

13 - For the second day in a row a record low was set (25° yesterday, 23° today), just two years after another set of back-to-back record lows in November, on the 10th and 11th (25° and 24°, respectively).

16 - It was a clear, windy and unseasonably cold day (high/low of 42°/31°), with exceptionally low humidity.  Falling to 13% around mid-day, this was the lowest humidity reported in November in the years of the 21st century.  It was also the only date outside of March and April with a humidity level this low (earlier this year the humidity also fell to 13% on 3/24).

 

DECEMBER

2 - A sloppy early winter storm gave Central Park its first measurable snowfall of the season.  After a morning of rain, a changeover to light snow occurred around noon and by midnight 1.3" had accumulated (an additional 0.3" fell overnight).  The accumulation might have been greater but the temperature held at 33° for much of the afternoon, not falling to 32° until after 8:00 PM.  This snowfall was about a week earlier than the typical first measurable snow but three weeks earlier than the average date of the first snowfall of an inch or more.

4 - With a high/low of 39°/32° this was the fourth day in a row in which the temperature never got out of the 30s.  This was the longest such streak since one of five days in January 1998.

14 - The rainstorm that moved in yesterday at mid-afternoon continued overnight and ended around 8:00 AM today.  1.96" of rain was measured (0.81" yesterday, 1.15" this morning), bringing the month's precipitation over five inches (5.04"), making this just the third December to have more than five inches in the first two weeks of the month (1983 and 1996 were the other years).

18 - An Arctic front bringing the coldest weather since the beginning of February triggered a burst of snow at around 4:00 PM.  As the front approached a "Snow Squall Warning" was issued mid-afternoon (although unusual for New York, a similar warning was issued on 1/30 of this year).  Less than an inch of snow accumulated but it came in such a short amount of time that it produced whiteout conditions for about ten to fifteen minutes.  By midnight the temperature was down to 21° on its way to 16° by daybreak on the 19th.

19 - With a high/low of 25°/16° (fourteen degrees colder than average) today was the first day this winter with a high of 32° or colder.  Although it was close to the average date of this occurrence, it was the latest date since the winter of 2015-16 when it didn't occur until Jan. 5.  Today would end up being the coldest day of the winter.

30 - It was a rainy and cold day with the temperature hovering around 40° for much of the day.  Rain that began yesterday evening continued for a little more than 24 hours, amounting to 0.99" (0.74" of it fell today).  In the waning hours of the storm high winds kicked in, with a peak gust of 39 mph.  The rain brought December's precipitation total to 7.07", making it not only the rainiest month of the year (passing May, which had 6.82"), but also making it one of the ten wettest Decembers, tied for fifth place with Dec. 1969.  By coincidence, last December also placed among the ten wettest (now ranked ninth).

Finally, today was 2019's 147th day with measurable precipitation, the third most on record (and tomorrow would also see some rain in the evening).  However, it ranked 28th for the total amount of precipitation measured.  (Last year, which had the most days of precipitation, ranked fourth in terms of amount of precipitation.)

Reviewing 2018's Top Weather Stories: Raindrops Kept Falling On Our Heads

2018 recap

 

It was a wet year, indeed, ranking as the fourth wettest on record (behind 1983*, 2011 and 1972).  However, it began on the dry side, with January receiving just 2.18" of precipitation (it was the third drier than average month in a row, with just 5.97" measured in total; and five of the six years preceding 2018 had below average rainfall).  And while the amount of precipitation that fell during the first half of the year was close to average, the rain gauge worked overtime in the second half as 40 inches was measured, 56% greater than what fell in the first half (five of the six months had six inches or more of precipitation).  And although the year wasn't the wettest on record, it did claim the crown for most days of measurable precipitation.  As 2018 came to a close it seemed fitting that it ended with a soaking rain on New Year's Eve, making it the wettest 12/31 since 1948, and the first time since 1994 that rain fell as the ball dropped in Times Square.

* An argument can be made for 2018 being ranked third because 1983's claim as New York's wettest year has been called into question after it was revealed that the rain gauge in Central Park was broken for a large part of the year, allowing rain to enter from multiple.

Now let's shine some light on the year's other major weather stories:

  • The year began with the continuation of a two-week cold wave that started the day after Christmas 2017 and lasted thru 1/8, making it the second longest on record (average high/low for its entirety was 23/13).  During this cold wave the biggest snowstorm of the winter snarled the City with nearly ten inches of wind-blown snow on 1/4.
  • February was the mildest on record (pushing Feb. 2017 to second place) and featured a temperature of 78° on 2/21 (35 degrees above average); this was the warmest reading ever posted in the first two months of the year.
  • March was cold (at 2.4 degrees below average it was colder than our mild February) and stormy, with four nor'easters wreaking havoc.  The last one, which occurred the day after the spring equinox, dropped 8.4" of snow, the biggest March snowfall since 1993 (and 0.1" more than the snowfall of March 1-2, 2009).
  • Cold spring weather continued into April (3.6 degrees below average), which saw the biggest April snowfall since 1982.  5.5" fell the morning of Easter Monday (4/2), forcing the Yankees to postpone their home opener.  2018 suffered through the coldest March/April since 1984.  (However, among all years it ranks 56th as springtimes before 1950 were significantly chillier.)
  • May was a reversal of March-April and was the sixth mildest on record.  The month began on the hot side, with highs in the 90s on the 2nd and 3rd; later in the month there were three days with highs in the upper 80s.
  • A severe, quick-moving thunderstorm during evening rush hour on 5/15 caused extensive disruptions (including my flight to JFK which was cancelled).  Then six months later a surprise snowfall during the afternoon and evening was even more debilitating, snarling the evening commute for hours.
  • Despite May's warm conditions, Mother's Day was chilly and overcast, with a high/low of 54/52.  By contrast Father's Day was sunny and hot, with a high/low of 91/66. 
  • The year's rainiest period was a six-week stretch in July and August (7/12-8/22) when 15.77" fell (nearly ten inches above average for the period).  This included a deluge of 2.24" in little more than an hour on 7/17.  However, the year's biggest rainstorm occurred in April when 3.29" fell on 4/15-16. 
  • The latest dates for a 80-degree and 70-degree low were reported on 8/29 and 10/10, respectively.  The year had 55 days with lows of 70° or warmer, the fourth most on record (following 1906, 2005 and 2015, and tied with 2010).
  • A surprise snowstorm on 11/15 (6.4") was followed a week later by a frigid Thanksgiving Day (high/low of 28/17).  This resulted in the coldest temperatures ever encountered during the the Macy's Thanksgiving Day parade - and the following morning was even colder, with a low of 15°.  After this early taste of winter there wouldn't be another measurable snowfall or colder temperatures for the rest of the year.
  • Like the majority of years this century 2018 ranked among the 25 warmest years on record, ranking 18th.  However, it wasn't as warm as the previous three years (2017 ranked 14th, 2016 ranked sixth and 2015 placed ninth).
  • Finally, 2018's diurnal variation between its average high and low was the smallest in more than 100 years (2003's and 1996's were close behind, 0.1 degree wider).  Interestingly, there are 15 years with smaller variations, all which occurred between 1878 and 1910.    (Many thanks to Eugene Demarco for sharing his analysis with me.)

Intriguing Questions Readers Have Asked About New York's Weather

Question marksMany of us find weather reports of interest because they help with the planning of our day.  And historical weather information is of value as well.  As publisher of this blog I regularly get e-mails from attorneys, novelists, scholars, and persons researching family history who are seeking information about past weather conditions (their questions differ from those found in the "Comments" section of the blog, where weather hobbyists make observations about my analyses or recount an experience they had during a weather event).  On average I get one or two requests every month.  In this post I share some of the more interesting questions I've received. 

 

DEC. 16, 2018
SUBJECT:  WEATHER ON FATHER'S DATE OF BIRTH
 
I‘m doing some research about my dad. He died in 1991 at the age of 49.  He was from the Bronx and I’m trying to find out what the weather was like on June 3, 1942I know this is odd – I thought it would be easy to find out – but Google has been of little help.  (My dad was amazing – gay – and one of those lost to the AIDS epidemic.)  I stumbled across your blog and thought you might be of help.
 
Thanks for any light you could shed on the weather. As I near the age he was when he died - I’m trying to trace my dad's story. And the weather seems as good a place as any to start.
 
MY REPLY:   Hi Delia, you came to the right place for the information you were looking for.   June 3, 1942 was an overcast and cool day in New York.  The high/low was 70/52 (the average for early June is 75/59).  The day's low was the same as that of June 1 and 2, which were the coolest readings of the month.  Winds were out of the northeast (off the ocean) and that's largely the reason for the cloud cover.  There were some sprinkles before sunrise but nothing consequential.
 
 
DEC. 9, 2018
SUBJECT:  PLANNING AN OUTDOOR WEDDING
 
I saw your blog on NYC weather and had a question for you.  I am getting married next fall and we are booking a venue with outdoor space in NYC.  I wanted to ask you - when do you think there is less of a chance of a wash out - in mid September or mid October?  And which date do you think has better chance of good weather?
 
Appreciate any guidance from your expertise!
 
MY REPLY: Hi Matt, congratulations! As you might imagine, it's not a question with an easy answer (but not as challenging as a question from a colleague at work who was planning an outdoor wedding that had flags & balloons and wanted to know the chance of high winds).  No matter the date, even during traditionally drier times of the year, every calendar date has experienced significant rainfall (or snow).  However, on average, a calendar date sees measurable precipitation in NYC in one out of three years; however, this considers precipitation that's fallen anytime during the day, so this means the chance of precipitation during a particular time of day would be less than that. 
 
With this said, you'll be happy to know that the period you've chosen for the wedding is the time of year in New York that tends to have the most dates least likely to see rain.  In fact, half of the 25 driest calendar dates have occurred between Sept. 8 and Oct. 17, including eight of the ten driest dates. 
 
 
NOV. 25, 2018
SUBJECT:  WANT SNOW!
 
As strange or odd as it may seem, I like snow.  Living in Chicago, I especially like the way it quiets and slows down the city. I have been in NYC when it snows, most notably on the snowiest Thanksgiving Day on record, 1989, during which I enjoyed the Macy's Parade from the curb.  I've accidentally experienced other Big Apple snow falls of much lesser amounts.  Anyway, I know that you are a recorder of weather not a predictor of such, BUT based upon your records, what are some dates in NYC's weather history that have experienced a snow fall? My reason for asking is . . . as silly as it may be, I'd like to be in Manhattan during a snowstorm, so knowing the potential dates, based upon historical data, could help me plan. Now, yes, I know, that today's weather predictions are probably better than basing a decision upon history repeating itself, and I will keep watching TV for reports of those east coast circumstances that produce one of those famous nor'easters, but again, I was just wondering if there are any NYC dates that have been more reliable for snow than others.
 
MY REPLY:  Hi Charles, thanks for you intriguing question.  Not surprisingly, and as you suggested, I don't think any information I have is going to be of much help.  Probably similar to Chicago, the prime time of snowfall in New York is from mid-December thru mid-March; however, every season is different.  For instance, last winter we had four snowfalls of five inches or more, but only one of them occurred during this period.  Looking at all years in which records are available for Central Park (since 1869), February is most likely to see snowfalls of six inches or more.  And the four dates that have received this amount the most times are: Feb. 4, Feb. 12, Feb. 25 and Dec. 26.  It's happened seven times for each date, which means about once every 21 years, so it doesn't happen all that frequently.
 
A word of caution.  If you tried to schedule a trip when a snowstorm is predicted you might be disappointed because many predictions don't come to fruition because either the track of the storm changes slightly or the temperature in Manhattan may warm just enough to result in sleet or rain instead.  Or the storm may strengthen at the last minute or the storm track may change and take us by surprise (as was the case a few weeks ago).
 
So there you have it.  My question to you is, why not just go to Chicago for its big snowfalls?  :)

SUBJECT:  TODAY'S SNOW - QUESTION
 
Quick question which I thought you might know - with today’s (11/15) relatively early measurable snowfall in Central Park - is 2018 one of the shortest periods of no-snow in NYC…. given that the city got 5.5” on April 2?

Was debating this earlier with one of my weather geek friends.
 
MY REPLY: Hi Mike, 2018 is tied with 1940 for eighth shortest time between last snowfall of the previous winter and the first snowfall of the next winter.
 
 
Chart - days between last and first snowfall
Note: Average # of days between last & first snowfall is 261 (3/21-12/8).

SUBJECT:  NYC DAILY HIGH TEMP DATA
 
Rob, I've developed a new way to visualize large chronologically-ordered data sets (US Patent #9,747,652) and was looking to test it on a simple data set.  I've been trying to find a downloadable database that provides the daily maximum temperature for the Central Park weather station, which has been recording temperature data since 1869.  

I know that the data exists, but I'm not able to find it (neither have the librarians who have tried to help).  I found your website and thought that if you didn’t have this data, you’d know where to get it.

I've found composite information (average high & low temps, highest daily temps, etc.), but not true daily numbers.  I am “simply” looking for the daily high temp reading at the Central Park NYC or the last 54,645 days.  Shouldn’t be that hard, right?
 
MY REPLY:  Hi Chris, unfortunately, none of the sources I refer to for my blog are set up in a way that makes it easy putting together all of the daily highs/lows from 1870 onward.  The source I use provides daily highs/lows for individual months by each year.  Double click here for the link.  But, who knows, with your knowledge of spreadsheets, perhaps you can find a way to gather all of the information together.

SUBJECT: SPANISH-AMERICAN WAR

I’m a writer working on a book about the build-up to the Spanish-American War. Several of the events that I’m describing took place in Manhattan in 1896 and 1897. I’d love to give an evocative description of the weather on those days, to help bring the events to life, and I came across your weather archive online. Do you think you could help me locate temperature and precipitation figures for a few dates, or point me toward a database with that information? I’d be so grateful for any help you can offer.

MY REPLY:  Yes, Wil, I can help.  The link (double click here) will take you to a NWS site for New York that I use frequently.

SUBJECT:  DEATH FROM EXPOSURE TO EXTREME COLD?

I work for NBC4 in Washington, DC and a co-worker has a question about a non-record event from 1948.  She is researching her family tree and the trip down the rabbit hole has her wondering.  Her grandmother’s body was found on Nov. 24, 1948 but there is reason to believe she may have died several days earlier.  Foul play is not suspected in her death but cold and snow are.  Is there any way to get the high/low/rain/snow data from Nov. 17-24, 1948?  I checked NYC's Nat'l. Weather Service site but since no records were set during that period it’s hard to say exactly how extreme the weather may (or may not) have been.  Any help pointing me in the right direction would be appreciated.

MY REPLY: Hi Chuck, the circumstances behind your friend's request are quite unique as I occasionally get requests for weather conditions for dates of births, but never one this tragic.  The weather during this period (Central Park) had above average temperatures and included the warmest reading of the month, 74° Nov. 20. FYI, the month as a whole was very mild, and until 1979 was the mildest November on record.

 

MARCH 21, 2018
SUBJECT:  COGNITIVE DISSONANCE OF OUT OF SEASON SNOWFALLS

I’m writing a blog post about the cognitive dissonance created by today’s snowstorm in NYC. The idea being that snow in spring creates dissonance because we believe it shouldn’t happen.

Interestingly, I found a journal entry in my journal from two years ago today that mentioned it snowed.  I was trying to research the history of spring snow in NYC - whether minor snow showers or major storms like today (which everyone is calling major, but it’s not sticking on the sidewalks on 14th Street!).  I came across your site and was fascinated by it.  I saw  your post about major snowstorms but was wondering if you happen to have records of all the snow in March/April - specifically after the spring equinox (so early March wouldn’t count for this).  Maybe I’m just not seeing it on your site, but I'd love to point to evidence that this happens more than we think.

If it’s on your site, can you please point me to the link?  If it’s not on your site but you have the info, would you mind sharing it with me.

I will of course attribute the info back to you with links (Editor's note: she didn't).  If you want to check out my site, I blog at http://mymeadowreport.com.

MY REPLY: Hi Renee, significant snowfalls from mid-March onward happen infrequently in New York, especially accumulations of six inches or more, so today's snowfall stands out.  The 8.4" that accumulated today in Central Park, which is a significant amount in mid-winter, is the eighth biggest snowstorm this late in the season.  Before today the most recent major snowfalls so late in the season occurred in 1992 (6.2" on 3/19) and in 1982 (the blizzard of April 6 that dumped 9.6").  A lesser amount, 4.0", fell on March 29, 1970 (Easter Sunday) and again on April 7, 2003.  (By the way, the snowfall you mentioned in your journal was likely the 4.5" that fell in 2015 on March 20.) 

I wrote a post a few years ago that you'll likely find of interest, about the harsh winter conditions that occurred in the second half of March thru early April in 1956, 1958 and 1967.  To read it please click here.

Here are snowfalls of six inches or more that have occurred after 3/15 (since 1870).  You'll notice that a majority of them occurred in April.

11.8" - March 20-21, 1958
11.6" - March 18-19, 1956
10.2" - April 3, 1915 (the day before Easter)
10.0" - April 12-14, 187
5

9.6" - April 6, 1982 (the Tuesday before Easter)
9.0" - March 22, 1967
8.5" - April 1, 1925 (the Wednesday before Easter)

8.4" - March 21, 2018
8.0" - April 12-14, 1892 (4/14 was the Thursday before Easter)
6.7" - March 16-17, 1956
6.5" - April 5, 1944 (the Wednesday before Easter)
6.5" - April 8-9, 1917 (4/8 was Easter Sunday)
6.4" - April 6-7, 1938
6.2" - March 19,1992

 

JAN 7, 2018
SUBJECT:  NEW YORK CITY SKY CONDITIONS
 
Here is, I think, a strange request.  Is there a record of sky conditions (cloudiness) for 1932?
I am pretty sure I have a memory during my first six months. I remember looking out the window from my crib at a full moon and a clear sky. I was born in January 1932 so the period of clear sky, full moon should be around July.   Any help would be greatly appreciated.

MY REPLY: Robert, although your request is somewhat out of the ordinary (from the questions I usually get), you'll be happy to know that daily information is available about sky conditions for 1932.  Unfortunately, for some reason the monthly summary report for July is not available from the site I use.  However, looking at June and August, skies were clear on the following dates (based on the 9PM reading):

June 7 thru 10; June 17; June 20; June 22 thru 24
Aug 5; Aug 9;Aug 15;Aug 19;Aug 22 thru 26


Please keep in mind that these sky conditions are based on observations from Central Park, so they might be different elsewhere.

SUBJECT:  APRIL BLIZZARD IN 1961?

I was reminded of some history today when a friend sent me this link:

https://i2.wp.com/allenginsberg.org/wp-content/uploads/2015/12/Doc_3000_beatniks-riot-1.jpg

I was wondering how I could have missed it. I flew to San Francisco, I thought in April '61, and my plane's departure was delayed from LaGuardia by a day, thanks to a blizzard.  I swore I'd never come back, and ironically wound up living in Barrow, Alaska, from 1992-1999.

I did want to check my memory, though. I couldn't find a blizzard that April on your site and went all the way back to February 7th to find one.

I also found this, but there was no date:

https://www.youtube.com/watch?v=cIT4BRyz4qg

Can you tell if there actually was an April 1961 blizzard?

MY REPLY: Hi Frank, there was no blizzard in April 1961 (the high/low on April 6 was 53/44).  However, there was a blizzard 21 years later on that date that dumped nearly ten inches of snow on NYC.  The YouTube video is likely from the snowstorm of Feb 3-4, 1961, which dumped 17.4" on NYC.

 
NOV. 7, 2017
SUBJECT:  MOVING TO NYC

My name is Gabriel and I am from Barcelona. I am so happy of having found out your website full of weather data and events in New York!  There is so much information, it is amazing! I have also collected so many weather events from my country as well (but not published on the net, just notes and newspapers).

Like you, weather has been my hobby since I was 8 years old (now I am 33) and I started to collect weather data when I was 13 years old, and so far I am so proud of having a 20-year climatic record of my village!

I discovered your website because I was looking up some weather data from New York. Why New York?  Because I am moving there the next year.  My partner is from NYC and I have decided to move, to settle and start a new life.  I hope to find a meteorology or climatology ... if not at the beginning, later on. 

I will be living in Queens in an apartment. I will have to ask for permission to install a pluviometer on the terrace.  Not an automated one... I want to keep measuring the rain exactly as I have done it so far - with a test tube.  So that's why I have so much interest of collecting weather data from NY. The climate of NY is much more interesting than the one in Barcelona, I will be excited to be experiencing cold snaps in winter.

Do you still collect weather data in NY?  Where can I find daily data from Central Park or JFK, LGA airports? Or any official observatory?

MY REPLY: Hi Gabriel, I'm always happy to hear from other weather enthusiasts.  However, I'm not as motivated as you since I don't have a rain gauge, perhaps because Central Park's weather observatory is only four miles away from my my apartment.

I visited Spain ten years ago and went to Madrid and areas south (Toledo, Sevilla, Granada, Marbella), but I didn't get to see Barcelona.  I suppose your weather is on the mild side, perhaps even tropical.  Although I don't keep my own records of the weather anymore I still have my calendars of data when I did it as a boy in Pittsburgh.

Below are links that you'll find very helpful in understanding the climate of New York.  They provide monthly reviews of weather conditions going back more than 100 years for New York City/Manhattan and more than 60 years for LaGuardia Airport and Kennedy Airport (both airports are in the borough of Queens).  Central Park is the official reporting station for New York's weather information.  Not only will you find monthly recaps but recaps of each year.

CENTRAL PARK (Manhattan)

LAGUARDIA AIRPORT (Queens)

KENNEDY AIRPORT (Queens)

Yes, New York's weather can be very interesting because of it being situated along the East Coast.  And although our temperatures don't get extremely cold we do get our share of snowstorms.  Additionally, because of our proximity to the Atlantic Ocean summers aren't quite as hot as cities further inland, such as Philadelphia and Washington DC.  However, summer evenings/mornings can be very warm since all of the concrete and high concentration of office buildings prevents heat from escaping.

Again, it was a pleasure reading your message.  If you have any trouble with the links, or if you have any additional questions, please don't hesitate to contact me.  And I hope you enjoy living in New York.

SUBJECT:  Steven Fybish

Hi Rob, thanks again for your blog.  Not sure if you've ever heard of or been in touch with this guy, but before the Internet, he was the only person I was aware of who was into NY weather statistics. I tired to contact him a couple of times via e-mail years ago but never heard back, although I wasn't sure if I had the right contact information.

https://www.nytimes.com/2017/09/06/nyregion/stephen-fybish-who-had-much-to-say-about-the-weather-dies-at-80.html?ref=todayspaper

MY REPLY: Hi Ken, yes I had heard about Steven and recall reading a Times article about him a number of years ago.  Thanks for sending the link to his obituary.

 

JULY 27, 2017
SUBJECT:  SEEKING NYC PRECIPITATION FOR DISSERTATION

I am a hydraulic engineer in Hungary and - as part of my work - I collect and analyze data of the precipitation of my home city, Budapest. I work on my PhD, the topic is of course the rainfall data collection and analysis of Budapest.  In my thesis I would like to make studies on the spatial distribution and extent of heavy rainfalls.  For this work I plan some comparisons of cases of cities which have extended rainfall gauge networks (in my city we manage a network of 55 gauges in cca 550 km2).  By this idea I could get data from Toronto in the past months from an on-line database.

Hopefully I can get to New York City in the first half of September as a tourist, and I thought that this occasion could be supplemented by getting to know the rainfall measure network and data proceeding of NYC, even to meet some experts of this question. 

Browsing on the net I've found your web site "New York City Weather Archive" so I turn to you with my request of help.  Who can I seek with my interests, where can I get at least daily (hopefully more detailed) data from rainfall gauges of NYC as further data base for my study?

MY REPLY:  Hi Tibor, I can provide you with helpful information to get your thesis started.  In New York City, rainfall information is collected at Central Park (Manhattan), La Guardia Airport and JFK Airport.  It's available by year, month, day and hour.  Central Park's information goes back to 1869(Most cities in the US collect weather data, usually at their airports.)  The National Weather Service has a website that has all of this information. Click here for Central Park's information, which is arranged by month of each year.

Additionally, I've written a number of posts about excessive rainfall in New York City that you may find helpful:

MAY 4, 2017
SUBJECT:  MAY 1974 - SNOW?

Thanks for sharing your enthusiasm for weather on your blog. I teach journalism at St. John’s University in Queens, and I’m reading a student paper in which the mother recalls stepping off a plane at JFK on May 4, 1974, emigrating from the West Indies, and seeing snow on the ground in Brooklyn.  I just read your Weather Archives, both the broad views and the close-up, and see that we had record-breaking heat at the end of April that year.  Is it likely that there would have been any snow that would have survived that heat? (Here in Queens, I have seen small mounds of snow on shady side streets survive late into the spring.)  I wouldn’t grade this paper down, of course. I’m just fascinated by the persistence of memory, the specificity of recall, that might not have been accurate yet vivid and “true” in the mind of the mother.

MY REPLY: Wayne, I'm glad your student's paper resulted in your finding of my blog!  There has never been accumulating snow in NYC in the month of May.  And on May 4, 1974 the high/low at JFK was 64/49 (and the last measurable snowfall that winter was on 3/29).  I also looked at the previous month in case he had the month wrong, but April 5 had a near-identical temperature, 63/50.  I thought that maybe she saw hail on the ground, but there was no precipitation on May 5.  Memories can play tricks on us - perhaps she was mixing up another trip to JFK that was during the winter.

 

MARCH 28, 2017
SUBJECT:  WEATHER CONDITIONS ON NIGHT OF 1931 MURDER

Hello Rob!  I enjoyed visiting your blog.  I am a baseball historian from Chicago.  In July 2017, I will be giving an oral presentation at the SABR (Society for American Baseball Research).  I am researching a murder homicide that took place in Brooklyn during the early morning hours of Oct. 5, 1931.  Two men visiting a speakeasy got into a vicious baseball argument during the 1931 World Series and a fist fight began leaving one man dead and the other incarcerated.  

I was hoping that you may be able to search your archives and tell me what the weather forecast was for the early morning hours of October 5, 1931 in Brooklyn.  I would be most appreciative and I will recognize you assistance by name, website, etc. when I give my presentation.

I thank you in advance for your time.

MY REPLY: Hi Matthew, I'm glad you found my website.  I happen to be a baseball fan so I'm glad I can help you out.  Oct. 5, 1931 came in the midst of an unseasonably warm stretch of days at the beginning of October that had temperatures that were more like August.  Oct. 5 had a high of 84°, which was seventeen degrees above average.  In the early morning hours of that day temperatures were close to 70° under fair skies (that's even above what the typical high should be that time of October).   

 

MARCH 7, 2017
SUBJECT:  SOLAR PANELS

Hi Rob, I would like to know if there are hour-by-hour, day-by-day records of sunny days. From January 2016 to the present.  I had solar panels installed about a year ago and I feel my local utility company is fixing the numbers to their own advantage.  Solar is based on direct sunlight not whether the temperature is hot, warm or cold.  And in this mild winter we've had, I don't see how they justify their rates. Please let me know.

MY REPLY: This is a tricky one since cloud cover can be very different from weather station to weather station.  Last summer, for instance, Central Park was much sunnier than Newark, LaGuardia or JFK.  And it can be very different compared to what part of the New York metro you live in.  With that said, the National Weather Service publishes monthly weather recaps featuring daily information; however, sky cover is provided for every third hour rather than hourly: 1AM, 4AM, 7AM, 10AM, 1PM, 4PM, 7PM, and 10PM.  If this might be helpful to you please let me know and I'll provide you with the link and instructions.

SUBJECT:  SCHOOL CLOSINGS

I enjoyed reading your post about New York City snowstorms from 1950 until 2016.  My wife, a former (if one from Da Bronx can ever be a "former" Bronxite) Bronx girl, claims she would walk to and from school uphill both ways in snowstorms.  She says school was never closed due to weather conditions. In your research on snowstorms, did you ever find information on any school closing in the 1950s and 1960s?  I would appreciate any information you may be able to give me.  Thank you.

MY REPLY:  Hi Michael, school closings is one aspect of NYC's weather that I haven't researched but I often hear colleagues who grew up in New York say that schools rarely closed before the 1980s.  I think part of the reason is that nowadays more kids and teachers take buses, drive cars and travel greater distances compared to the years pre-1980.  Also, parents today seem more protective and worried about the safety of their kids.  Finally, since so many parents are working it's a challenge for their schedules if their children stay at home.  

Also, especially since 2000 significant snowstorms have occurred with greater frequency than in the 1950s and 1960s. (So far, this current decade has had more snowfalls of 8"+ than any other full decade going back to when records first began in the 1870s.)  

Although the this link addresses 11 school closings since the blizzard of Feb. 1978, I thought you might find it of interest nonetheless.


Sorry I couldn't provide you with any statistics to answer your question.

SUBJECT:  CENTRAL PARK TEMPS

As part of global warming research, I would like Central Park temps for 1am and 1pm on Oct 1, Oct 11, Oct 21, and Oct 31 for as far back in time as the data exists.  How do I get it?

MY REPLY: Rod, that's quite an ambitious project you're undertaking!  The link below from NOAA's Local Climatological Data website will enable you to find daily observations from Central Park going back to 1900 - with some limitations.  The months going back to the early 1960s have temperatures for every day on an every-three-hours basis (lucky for you, 1AM and 1PM are two of the times that are provided). The months before 1950 provide observations for every hour.  Unfortunately, the years during the 1950s thru early 1960s, and some years during the 1990s, have no hourly observations.  And for some reason there are no monthly reports from the late 1940s and some years before 1920.

SUBJECT:  METS & YANKEES WEATHER STATS

When I was doing some research about big snowstorms in March, I happened to come across your list of weather conditions at all the Mets and Yankees home openers since 1970. Awesome work!

I’m planning to write a story about those weather patterns, along with the weather patterns for Phillies’ home openers, since we have a lot of readers in central and southern New Jersey who root for them.

I’m doing my own research on the Philly home openers, and it’s a grind!

Anyway, could I give you a call to ask you a few questions about your research?  Or could you answer them in an email? I think you deserve a lot of credit for all the work you did, and I’d like to get a few comments from you. 

MY REPLY:  Hi Len, below you'll find my answers to your questions.

— What motivated you to do all that research on the Mets and Yankees weather conditions?

Writing a blog, generating traffic is a big motivator so I'm always thinking of new angles I can put a weather spin to.  After I had written about weather highlights of every calendar date I decided it would be interesting to write about highlights of the major holidays.  After I finished these I expanded my definition of holidays and included events like the day of the NYC Marathon, the Gay Pride Parade and then the home openers of the Mets and Yankees.
 

— How long did it take you to find all those records and sort through them?
It took a while (at least a couple of weeks), especially because I was working on the home openers of the Mets and Yankees in tandem. Not only did I have to look at the weather conditions for each date (focusing on conditions during the afternoon hours), I also examined the box scores so I could add information that would be of interest to Mets and Yankees fans. Just a few weeks ago I added the games from the 1970s.  By the way, the post about the Yankees' home openers is much more popular, generating seven times as much traffic as the Mets post.  
 
 
— Did you use data from the same weather observation station for both teams? (Central Park, JFK or LaGuardia Airport?) or one place for the Mets and one for the Yanks?  (I’m asking this because my editors asked me to confirm some of the info on my own to make sure it matches up with yours.)
For the most part the conditions are based on Central Park's readings.  However, since Shea Stadium/Citifield are very close to JFK I'd also look at those reports as well to see if there were any big discrepancies, a big consideration in the springtime since wind off the ocean can make JFK much cooler than Manhattan. In fact, I occasionally make references to that fact. 
 
— Why are you so fascinated by the weather?
It's something I've been interested in since I was in the sixth grade.  In fact, I went to Penn State with the intention of majoring in meteorology.  However, after my first physics class stressed me out so much (and I'd have to take many physics classes), I switched majors - to Advertising.  Note, however, that I'm not so focused on the forecasting aspect, but the historical angle.  I enjoy analyzing statistics so it's easy for me to find many unique ways of looking at the years of data available.  (Professionally, I work in media research for an ad agency, which puts my analytical skills to good use.)

SUBJECT:  PONDERING TEMPERATURE AVERAGES

When we all think of average highs and lows, they move linearly and in the same direction always.  Meaning, that after the peaks of July 23 or so, the high temperature and the low temperature., when they move, move one degree at a time lower and lower…albeit very slowly at first, but with increasing speed as the earth’s tilt takes over, less daylight, etc.  You never see that, for example, on December 1 the average high is 50° and then on Dec. 2, it’s 51°, and then on Dec. 3, it’s 50°.  It never works that way.  You know better than I do.  It’ll be 50° for a few days…. then 49°….. then 48°.  It always moves in the same direction, until about Jan.24 or so, and then it starts moving up again.

Climate norms use 30 year averages.  The NWS in the above example uses 1981 through 2010.  That means, (forgive me, I know it’s obvious), that if you added up all the high temperatures on Dec. 24 for that 30 year period, and then divided by 30, you’d get the average high.

Dec. 24 this year was truly remarkable.  From 1981 through 2010, the sum of all high temperatures has to equal 41x30, or 1,230 for that date.  I presume that there is some rounding in there, but not too much.  For the average high temperature to be 42°, the sum of the years would have to be at LEAST 1,245, because dividing that by 30 gives you 41.5, which would round to 42.  In turn, it could be as low as 1,215, which would be 40.5 degrees, which would then round up to 41 degrees.

By adding a number that is 31 degrees ABOVE normal, the daily “normal” high MUST move up a degree, creating the anomaly of having the average high temperature on Dec. 24 exceeding that of Dec. 23,when we all know the trend should be moving downward.

Let’s use my low example.  Let’s say that 29 years averaged out to 40.5 degrees for December 24.   40.5*29 = 1,174.5.  ADD 72 degrees to that, and you get 1,246.5.  Divide that number by 30 and you get 41.55 degrees – otherwise known as 42 degrees, which is one degree higher than it was on Dec 23.  And that’s using the low example.  If the average is truly 41 degrees, the equation is 41*29 = 1,189 + 72 = 1,261/30 = 42.03 degrees.  The high example puts us at 43 degrees when averaging.

I think you get my point, so I’ll stop with the math, but in sum, on ANY day where the high temperature is more than 30 degrees above the “normal” 30 year high for that day, it has to increase by the daily normal high by one degree and create an anomaly.

MY REPLY: Hi Robert, that's a very interesting take on the subject of season averages.  I never thought about it the way you presented it.  However, I believe the process of deriving the averages is a bit more complicated.  If you averaged highs and lows of every day of the year I'm sure you wouldn't see a smooth transition from day to day.  Based on my experience at work, graphs are created using many different data points and I'm sure NOAA's averages are based on a smoothing of all of the individual data points.  Also, since each 30-year period for averages is used for ten years, 2015's won't be part of the 30-year averages for another five years, when the 1991-2020 norms are introduced.

SUBJECT:  THANKS FOR HELP WITH MY NOVEL

I thought you might find it interesting that I just used your snowfall data for the first scene of my soon-to-be published novel, Pride's Children. It starts in Feb. 2005 (evening of the 25th), and I needed snow on the ground in enough depth to make the sidewalks slippery, with snow piled on the sides, as it gets in NYC.  I moved the scene from the 11th to the 25th (for plot reasons), so I had to check the snow and the moon’s phase (shifted from new to almost full in two weeks).

So thanks for putting the data up for people like me to use.

MY REPLY: Hi Alicia, I'm delighted I was able to help, thank you for letting me know.

I’m a journalist, author, and filmmaker — at work currently on an in-depth history of AIDS activism in New York City.  I have stumbled upon your blog, and your deep interest in local weather history.  I wonder if you might allow me to ask you from time to time for information from your deep archives. For instance, the early evening of Nov. 6, 1991? 

MY REPLY:  Hi David, I'm happy to answer any questions you might have.  Regarding Nov. 6, 1991, it was a chillier than average day (high/low of 52/34, eight degrees below average).  In the early evening the temperature was in the mid-to-upper 40s under mostly fair skies.

SUBJECT:  INQUIRY ABOUT NYC MARATHON WEATHER

What was the temperature at the start of 1996 Marathon?  Cannot find it anywhere.  I ran it in 3:49.07 (after crawling over the bridge and cramping after down slope of the Manhattan bridge). Still, it was awesome!

MY REPLY: Hi Steve, the 1996 Marathon (Nov. 3) was one of the chilliest. The temperature at 10AM was just 41° (after a low of 35°) and at 1PM it had risen to 48°, which was 11 degrees colder than average.  This year's Marathon wasn't quite as chilly in the AM but the high winds made it feel colder.  

By the way, if you haven't already seen it, I've written a post about weather highlights of past Marathons:  http://bit.ly/Sj2OVh

SUBJECT:  WHAT A SITE!
Hey There Rob, what a blizzard.  Thanks to your site I did a search and read some articles about
it. I was a 19-year-old Canadian boy living in New York on April 6, 1982. But what I'm interested is this...at about 3AM on April 7 I grabbed a cab at 73rd and Central
Park West for my place down in the Village. At the intersection of 7th Ave. & 33rd St., right
in front of Madison Square Garden the taxi went through a red light and slammed into a van
heading westbound on West 33rd. I went face first into the metal partition...nearly croaked,
as you
can imagine. Of course, I was in Bellevue Hospital for quite a long time and never even thought to search for any
newspaper reports or other documentation of my accident. After all my jaw being wired shut
was the least of my medical problems! So I was in no position to care at that time. I have no idea why, but tonight I thought I'd take a look online and see what I could find
without any luck. The fact that I'm back in rural Canada and you're in New York maybe you have an idea of
where I can search for any reports of my accident. Surely there must be something out
there considering how serious it was. If you have any suggestions I'd really appreciate it if
you could get back to me. Your site seems very comprehensive, that's why I thought you
might have some leads you could let me know about. Is there such a thing as Auto Accident
Databases? There is lots of documentation on the storm of course, and some mention of auto accidents,
but nothing more specific than references to a few pile ups and motorists being stranded
on various roads.
MY REPLY: Hi Larry, that's quite a story.  I'm glad you survived the ordeal. You may want to
check to see if the Daily News or New York Post have an archive of past issues.  Unfortunately,
since no one was killed, and since it occurred in the aftermath of an attention-getting
snowstorm, it may not have even been reported.  And although there is a database where
you can order official accident reports filed by the NYPD, it only goes back four years.     

I'm curious, did you move back to Canada after the accident or did you stick around longer? 
Were you here as a student at NYU?


Sorry I can't be of any further help - I have lots of sources for historical weather data, but
not this type of information.

SUBJECT:  GREETINGS FROM SWITZERLAND

I am a German speaking Swiss writer and am preparing my sixth novel, which I'd like to open at the beginning of the 20th century, perhaps on New Year's Eve in 1899 and continuing through January, February, March 1900. As you might imagine, it is important to have the historical truth and to know what the weather was like, i.e., if the rivers were frozen in New York City, especially on New Year's Day in 1900.  Do you know how i can get this type of information?  Do you have it?  Was it raining, snowy, cold, was the river frozen, windy, etc.  Or the contrary, warm etc.?  Are there any sites on the internet for the historical weather of New York?  I would be very glad if you could help me.

MY REPLY: Hello Catalin, the end of 1899 and beginning of 1900 was historically cold.  For eight days in a row, between Dec. 28 and Jan. 4,  the temperature never rose above freezing (0 degrees Celsius).  And there was just a little bit of snow.  Here is what the day-by-day temperatures were (high/low) in Celsius:

Dec 28, 1899   -2/-6
Dec 29, 1899   -3/-7
Dec 30, 1899   -7/-12
Dec 31, 1899   -7/-12
Jan 1, 1900      -7/-10
Jan 2, 1901      -7/-11
Jan 3, 1901      -4/-7
Jan 4, 1901      -2/-7  


Typical temperatures during this time of year are around 3/-3 C. (the formula for converting Celsius to Fahrenheit is:  Celsius temperature x 1.8 + 32 = Fahrenheit temperature.)

Despite this cold spell it's doubtful the rivers froze completely since temperatures that December before Dec. 28 were mostly above freezing.  Ice probably formed on the banks of
the Hudson or East Rivers, but not the entire river.  And the peak ice formation would have been on the last day of the cold spell.

SUBJECT:  HELP WITH DISPUTE REGARDING SNOW REMOVAL

I live in New York city and work as property manager for a building that has plenty of square feet to cover when snow removal is necessary. This means any accumulation, even an inch of snow, requires snow removal.  In the past few years I have worked many hours and responsible for snow removal. I was wondering if you can help me out, is there a website or some kind of information I can obtain for daily snow accumulation for past years?  I found some monthly websites, but not daily, meaning I can not find anything on a given day of the week.  Reason being, Rob, there were years where I worked with snow removal, and my employer owes me overtime pay that I must submit, but I no longer have the records for this and employer does not want to acknowledge that they have these records only because they no longer have my information. Which only means they want to avoid paying me.  I know this email is out of the ordinary and please forgive me if this is not something you know, but will very much appreciate your help and guidance if you do have some information you can share with me.  Thank You in advance.

MY REPLY:  Not to worry, Sam, daily weather data are available for New York.  Click here and you'll be taken a menu page from the National Climatic Center's website for Local Climatological Data (which is the source I use for my website).  The page you'll be taken to is for New York City and is arranged by month.  Every month has detailed information for every day, including snowfall.  This document also provides the amount of precipitation that fell by each hour. (Please note that the information is based on NYC's official measurement site in Central Park.)

SUBJECT:  REMEMBERING WARM FEBRUARY TEMPERATURE
 
Nice site Rob! I myself am and always have been a weather buff.  I was trying to navigate your site, and was wondering if you recall in the late '80s a period in February where we had temps in the '80s.   (During that decade I lived in NJ in Lake Hopatcong and then Highpoint.)  I think it was in the latter part of the decade.  (I also recall Dec. 1964 having a warm spell.)   Do you recall this?  Again, nice job.
                                                                     
MY REPLY:  Hi John, thank you for your kind comments about the blog.  New York has never seen any days in the 80s in February, but you may be thinking of February 1985 when we had a high of 75° on Feb. 24.  There was also a high of 76° on March 8, 1987.  The earliest 80-degree reading in NYC was on March 13, 1990 when the high reached an incredible 85° (36 degrees above average).  And regarding December 1964, there were three days in a row during the Christmas holiday (12/25 thru 12/27) with highs of 60° (but the month as a whole had sightly colder than average temperatures.)

I am working on a case that involves the murder of a livery cab driver in the Soundview section of the Bronx on Jan. 19, 1995 between 3:00 and 4AM.  A witness claimed to have witnessed the shooting from her bathroom window.  She even said that the window was open.  Her credibility has already been destroyed and the five people who were convicted and served 18 years in prison on the basis of her lies have been exonerated and are now free.  In any event I thought you might have ready access to what the weather was like in NYC at the time of the crime.  Can you share that with me and also let me know your source in case I have to back up my assertions about the weather.

MY REPLY: Hi Peter, the weather in New York at that time on 1/19 was on the raw side.  Skies were overcast, the temperature was in the upper 30s, with winds out of the northeast and there were some sprinkles of rain - but not enough for it to be measurable.

Please note that these were the conditions at the National Weather Service's reporting station in Central Park.  This information was taken from a monthly report published by NOAA's National Climatic Data Center.

Thank you for the post. I am wondering, however, if you know the average humidity for the races. I am thinking of just the races since '95 since we want the study to be applicable to future races.

MY REPLY:  Hi John, attached are the data you asked about.  In addition to each year's relative humidity, I've also included the temperature for each hour.  Please note that all this information comes from NYC's official reporting site in Central Park.

MY REPLY:  Hi Andy, there were no big snowstorms in 1977.  The largest snowfall was five inches and it occurred during the afternoon and evening of Jan. 14.  This preceded a major Arctic outbreak which saw the AM low go down to 2° below zero on Jan. 17.  That January was one of the nation's coldest on record.  The following year, however, NYC had two major snowstorms, one in January (13.6") and the other in February (17.7").

SUBJECT:  TEMPERATURE ON DAY OF 2003 BLACKOUT

I found your website after watching a movie on Netflix called Category 7 about a monster storm that could be shut down by cooling a city by shutting off the entire power grid.  It was entirely unrealistic in terms of how quickly they showed the city cooling off but it still was an interesting point.  Would a city, could a city experience ANY kind of rapid drop in temp?  I doubt it. It makes me curious about whether the temperature dropped AT ALL on that colossal day of the Northeast blackout, which happened at 4:10 pm on Aug. 14, 2003.

Do you have the temperature data for that afternoon and evening?  Perhaps best if it comes with data of the days before and after to see how the temp. was dropping naturally in the evenings.

I couldn't find a place on your page to search for data of particular days. Would that be hard to do?  Or perhaps you know of a website that already has that feature.  I tried NOAA's Data center but the site is NOT obvious as to how to access data.  For one, they use a shopping cart system - but it's free!

Appreciate your help if you can.

MY REPLY:  Hi Poonam, thanks for your question.  The power of hurricanes is generated when they're over the ocean, fueled by very warm water.  Once a tropical system moves over land it weakens considerably because it's no longer over its power source, i.e., water.  Furthermore, cities are cooled by a storm's clouds and rain (even if they are still in the mild 70s), so a storm would need to be attacked while over the water to have any chance to weaken it.  

Regarding the temperature in NYC during the blackout of 2003, a hot air mass was over the City so turning off the power and AC would have little effect on the temperature (especially since power was off for less than 24 hours).  The day before the blackout, 8/13, the high was 87°; the day of the blackout the temperature topped out at 91°; the day after it was 89° - but I don't believe the two-degree drop was attributable to the power being out.  But regardless, scientists would need to cool the ocean to reduce a hurricane's power - but that cooling might cause a chain reaction of other events that might result in other problems.

Hope this sates your curiosity.  Please let me know if you have any other questions.

SUBJECT:  IN SEARCH OF THE PERFECT CLIMATE

I saw that article about you and your weather blog in today's edition of MediaPost.  Very cool!

I've wondered about the availability and application of weather data archives.  Our Grand Poobah of meteorology here in Chicago, namely, WGN's Tom Skilling, manages regularly to come up with dang unusual statistics about most, highest, lowest, longest stretches, biggest changes, etc., etc.

What I'd love to see is a computer or phone app that identifies a PERSONAL view of where in the US the "best" weather is.  The key is everybody has a different idea of what "best" is.  I want to throw things at the TV when some anchor talks about how wonderful some 87-degree day is.  My personal "best" days would be: 70° +/- 8 degrees, humidity 10-30%, light breeze, 10-25% cloud, no precip.

From that, I'd love to see a list of the top 200 cities, ranked by the percentage of daylight hours that meet my criteria.  Better yet, a color-coded map!

My dream wanderlust-pleasing app would add a whole wealth of other personal preferences covering everything from crime and income levels (there are plenty of real estate apps that do that stuff), plus things like walkability and count of independent (non-franchise)bookstores and Italian restaurants.  And while realtors are prohibited from talking about religion or ethnicity, I wouldn't think other data suppliers would be prohibited from including that info and there is a positive case to be made for it:  if you happen to be a Bolivian Mormon, you might welcome finding neighborhoods that have others of the same persuasion.

One interesting measure that Census or Bureau of Labor Statistics (BLS) or somebody produces is average age of mothers upon first birth.  That would be very useful to home buyers who have kids.  If Mom is either 22 or 40 and has young children, she may well look forward to not being the unusual one on the block compared to other Moms.

Just rambling on!

MY REPLY:  Hi Kevin, thanks for your message - good to hear from you!

From what I've seen, most apps with weather info often just have very general data that, to me, indicates that the technicians don't fully understand the data.  They could go much further.

Based on your criteria, I think you'd enjoy living/visiting places out West, particularly in Colorado, Utah, northern New Mexico, eastern Washington and Oregon or Idaho - but only during the springtime and autumn.  And then, of course, there's always San Diego.  But if you have patience you'll probably experience these sunny, mild and dry days on occasion in Chicago as well.  Perhaps we enjoy them so much because they don't happen all the time.  Living in the Midwest, it's the blizzards, below zero temperatures and heat waves that make these moderate days feel so good.  You wouldn't want that all of the time, would you (I think I know your answer)?

SUBJECT:  FEB 1978 BLIZZARD

I'm revising a novel set in NYC in what i planned to make 1978.  The revision has been necessitated by a piece of weather history which I overlooked until very recently: the blizzard of Feb. 5-7.

I love your weather history, but i see it only goes back to 1979.  Do you by any chance have data on NYC during that storm, like when they closed and re-opened the schools, and when they closed and re-opened the subway?

Thanks for all you put into your website.  Great, great stuff.

MY REPLY:  Hi Susan, that blizzard hit New York the year before I moved to the City.  However, that hasn't prevented me from having a good amount of information to share with you that might prove useful:

  • The bulk of the snow fell over a 24-hour period between 3AM on Monday, 2/6 and  3AM on Tuesday, 2/7.  There was a final period of snow between 10AM and 1PM that dropped an additional one to two inches.  The snow fell heaviest from noon on Monday thru 3AM on Tuesday.  And there was thunder snow in the early AM hours of 2/7!
  • Gale force winds of 30-40 mph created drifts of 3-4 feet. Because this was a dry snow it drifted very easily.  Winds were strongest on Monday between 10AM and 7PM.
  • The total accumulation was 17.7".  This came less than three weeks after another big snowstorm dumped 13.6" on 1/19-20.  In fact, in less than two-months time (1/13 - 3/3), 50" of snow fell in New York/Central Park.
  • Schools were closed for one day, on Tuesday.  Regarding the subway, some lines with outside tracks were shut down, but not the entire system (a system-wide shutdown has occurred just twice - when Hurricane Isabel hit in Aug. 2011 and Sandy in Oct. 2012).
  • I recall seeing a photo in Time Magazine showing tenor Luciano Pavarotti standing outside with a snow shovel at Lincoln Center where one of his performances was canceled due to the storm.  I believe Broadway shows were also canceled on Tuesday evening.
  • Although this storm was debilitating for NYC, it was Long Island, Boston and New England that were especially hard hit (similar to last week's snowstorm). 
  • A week later a smaller system dropped four more inches of snow (and another five inches fell in early March).  There was at least one inch of snow on the ground in Central Park through March 11.

Please let me know if you have any questions.  And good luck with the book.

> The rainiest of all the Sundays was May 23,1999 when 0.30" fell, and most of it was between 9AM-8PM.  This was  the only Sunday in May 1999 that had rain.
> May 2000 had rain only on the 21st and it was just 0.03".
> May 2000 had rain only on the 27th when 0.08" fell.
> May 2001 had rain only on the 12th when 0.16" fell (off and on in the AM and then between 5-7PM).
> Like all the other Mays, May 2002 had rain on just one Sunday.  It fell on the 25th but it was just 0.01".

SUBJECT:  NYC TEMPERATURE ON JUNE 8, 1980

Hello from a former gay NYC dweller.  I love your gay blog and I am using your weather blog in my novel, set in 1980, just before the AIDS epidemic.  I left NYC that year to move to Portland, Oregon.  The chapter I am currently writing takes place on June 8, 1980.  From you blog I learned it rained on that date.  Do you know the temperature that afternoon?

If it is somewhere on your blog, could you let me know so I don't have to bother you again. The novel is a romance about two men in 1980.  I learned the Tony Awards were the night before.

Thanks for both blogs-- enjoyable, useful.

MY REPLY:  Hi Jason, thanks for your nice message.  I'm delighted that you're a reader of two of my blogs!  Coincidentally, I've been reading a gay novel titled Running In Bed which is about a young man's life/experiences in NYC between 1977-1987.   

Regarding your question about June 8, 1980, a strong cold front caused the temperature that day to plummet from 80° in early afternoon to 52° by midnight.  The next morning's low was a very chilly 47° - and NYC hasn't had a June reading that low since then.  (However, July/August/Sept of that year were unseasonably hot.)

SUBJECT:  WEATHER DURING METS GAME

Hello.  I was in New York for a Mets game in July 2011. I had to take an early flight home because of severe thunderstorms and missed the game.  Can you clarify for me if on July 17, 2011 New York had severe  storms?  I can’t remember if it was that day or July 24 or July 31. I know it was one of those Sundays.  Thanks for your help!

MY REPLY:  Hi Rhonda, although no rain fell the date would have to have been July 17 because that was the only one of the three dates in which the Mets played at home (they played the Phillies).

FYI, a little bit of rain fell late in the afternoon on July 24, but it wasn't from a thunderstorm.

Very Wet 2018 Ends With Wet December

Rainy times square

 

2018 was New York's fourth wettest year on record (third if the disputed 1983 is excluded) and the final month of the year followed that theme.  December was the year's fifth month with six inches or more of precipitation (all of them occurring in the second half of the year).  The month ended with the wettest New Year's Eve since 1948, and for the first time since 1994 rain fell during the ball drop in Times Square (pictured).  Most of the month's 6.51" of rain (the ninth wettest December on record) fell after 12/13.  This followed a ten-day dry spell, which was the longest in more than a year.  Four days had an inch or more of rain, all in the second half of the month. 

 

December was 2.6 degrees milder than average.  The month started out colder than average, with Dec. 1-13 averaging three degrees below average, then a shift occurred and the rest of the month was nearly six degrees above average.  The final twelve days of the month all had above average temperatures (as did sixteen of the last eighteen).  The range in temperatures was rather narrow, from 24° to 61° (the coldest reading in December is typically in the upper teens while the mildest reading is in the low 60s).

 

November 2018 was snowier and had colder readings than December (two days had lows in the teens).  Typically December is ten degrees colder than November but this year it was only four degrees colder.  Just ten other Decembers have been closer to November's average temperature.

 

Chart - nov vs dec

 

After 6.4" of snow fell in November (all on 11/15) there was just a trace of snow in December.  This was the twentieth December on record with a trace of snow or less (nine of them have been in the past 25 years).  And it joined a handful of Decembers with much less snow than November.

Finally, December had the same average temperature as March (40.1°).  December is typically about five degrees colder.  However, while the overall temperature was the same as March's, December's average high was about a degree colder than March while its average low was about one degree milder.  And while both month's had above average precipitation, March was much snowier, with 11.6" measured.
