Reviewing 2018's Top Weather Stories: Raindrops Kept Falling On Our Heads
January 2019 Weather Recap: Average ... But With a Few Flourishes

Weather Highights of 2019





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.



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.  



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).  



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).



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.



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).  In total, there would be 15 days in the 90s this year, a slightly below average number.

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.  



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 (until 10/16, when 0.01" more fell).  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°, eleven degrees below average and the coolest high in five weeks.



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°).



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%.



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.) 



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.



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.)

It was hot as hell in early October. I'm ready for winter!!!!!!

Mark Chelchowski

I noticed that most of the snow in 2018-19 came "out-of-season" (December, January, & February). Did this past season have the highest amount of "out-of-season" snow or the highest percentage of "out-of-season" snow?


Hi Mark,

Yes, it was certainly a book-ended winter. It's tied for 18th place for most snow to fall outside of Dec-Feb. However, it ranked second for highest portion of a winter's snow to fall outside of meteorological winter, at 82% (16.8" of 20.5"). The winter of 1998 had the greatest portion of its snow to fall outside of MW, 91% (5.0" of 5.5"). The following link will take you to an analysis I did a number of years ago on this subject: https://thestarryeye.typepad.com/weather/2014/04/snowfall-during-meteorological-winter.html


125 days with measurable precipitation happened this year in the first ten months, the second most on record at this point in the year, trailing only 2018, which had 130 days of precip in the year through the end of October.


Despite how close they were, it should be noted that 2018 had about seven-and-half inches more precipitation than 2019 in the first ten months of the year.

Hello! I’m very interested in NYC’s weather history! I really love how you post weather highlights every year! Will you post the weather for 2019’s NYC Marathon?

I noticed on December 19 that the high-low was 25/16. I am wondering if that is the coldest first day below freezing in NYC.


In December 2004 the first reading of 32 or colder during the winter of 2004-05 was 21 degrees, on 12/20.


I know the answer is probably not, but was the low humidity on Sept. 11 2001 related to 9/11?


The low humidity was the result of a cooler, drier air mass that moved through on the evening of 9/10. This high pressure system is what brought the clear blue skies on 9/11.
