May 2021 Weather Recap: Close to Average Temperature & Rainfall Despite Very Chilly & Wet End

 Wet and chilly memorial day weekend

Last May, the month's weather highlight was an Arctic outbreak in the second week of the month that produced the coldest reading in May (34°) since 1891.  May 2021, meanwhile, experienced one of the chilliest ends of any May, as May 28-31 tied May 1884 for the latest four-day streak with lows in the 40s.  This chilly ending was responsible for the coolest three-day Memorial Day weekend on record. 

 

Chart - 3 chilliest memorial day weekends

Despite the month's chilly ending, an extended period of above-average temperatures from May 15-27,  that was six degrees milder than average, kept the month close to average, temperature-wise.  And a very wet May 28-30, in which 2.57" was measured, balanced what, up until then, had been a dry May (these three wet days had as much rain as the previous six weeks).  So, when all was said and done, the month was very close to average on both the temperature and rainfall fronts (-0.3 degrees, and +0.40").

 

Before May's chilly and rainy close, six days in the 10-day period between May 18-27 had highs in the 80s.  This included highs of 89° and 88° during the weekend of 5/22 and 5/23; by contrast, the following weekend had highs of 51° on both days.  This reading (which was eight degrees colder than the average low for these two dates) tied a record for the coolest high on 5/29, and set a new record (by four degrees) on 5/30.

 

Besides the last four days of the month, which were 13 degrees cooler than average, there was an eight-day period from May 5-12 that was five degrees below average.  (However, the chilliest reading of the month, 42°, was on 5/1.)

 

Finally, the last six days of the month all had measurable precipitation, the longest rainy streak since one of eight days in May 2019 (5/10-17).  However, this year's streak had a touch more rainfall (2.68" vs. 2.56").

How "Back-Door" Cold Fronts Impact New York's Springtime Weather

 

Back door cold front

 

For the most part, cold fronts move from west to east in the Northeast, but, occasionally, chilly air arrives from the opposite direction.  When it does, this occurrence is known as a "back-door" cold front.   Because such a front's winds usually come off the ocean, this type of front is often associated with overcast skies (sometimes with drizzle); its east-northeasterly winds bring damp and chilly air. 

These incursions of chilly air that come from the opposite direction occur mostly in the springtime, when their cooling effect is enhanced by the wintertime water temperature of the Atlantic Ocean.  In terms of geographic reach, these fronts mostly impact New York City, the Jersey shore, and New England; only occasionally do they extend as far inland as Philadelphia, Baltimore, or DC.

What follows are 40 instances of the more impressive back-door fronts that have come down from the cold Atlantic.  As you'll read, six of the years had two notable back-door fronts.

 

East to west

June 4, 1895 - Winds shifted from the southwest to northeast during the afternoon, breaking a five-day heat wave (its record highs on June 1, 2 and 3 are still standing).  Between 3PM and 8PM, the temperature dropped from 91° to 64°.  The following day would be overcast, with temperatures stuck in the 60s. 

April 25, 1915 - This date experienced, perhaps, the greatest temperature swings of any in New York's weather history.  After the temperature soared from 47° shortly after midnight to 91° at 3:00 PM, winds shifted to the east-northeast, and the temperature plunged to 52° by midnight.  This was the result of a strong warm front moving through for about ten hours (9 AM-7 PM), then being displaced by a back door cold front.  No rain was produced by the passage of these fronts.  Two days later, a similar scenario unfolded.  After reaching 92° shortly before 4:30 on 4/27, a back-door front moved through a few hours later, and the temperature dropped to 54° by midnight.

April 1, 1917 - In the span of just eight hours, the temperature plummeted from 83° to 44° as a back-door cold front moved through, and winds shifted from the southwest to the northeast.  This was the warmest reading of the month, with the next reading in the 80s not occurring for another seven weeks.

March 19, 1918 - After a balmy high of 76° was reached at 3 PM (a record for the date that still stands), the wind shifted from the southwest to the northeast, and the temperature dropped like a rock, and was half that reading by midnight.

May 23, 1925 - After the high reached 91°, winds shifted from the southwest to northeast late in the afternoon, and by midnight the temperature had fallen to 59°; the temperature on the afternoon of 5/24 was only in the upper 40s.

July 1, 1933 - After a high in the low 90s, a severe thunderstorm from 8:30-10:30 PM dumped 2.17" of rain.  During the storm the temperature dropped from 88° to 72°, where it stayed for much of the next 24 hours.  And on 7/3, afternoon temperatures got no higher than the mid-60s.  

March 27, 1939 - Today's high/low of 73°/39° followed one of 72°/39° three days earlier.  However, while the low on 3/24 was in the pre-dawn hours, the low today was at midnight after winds shifted to the northeast in the PM hours.  And the following day had temperatures in a narrow range of 35°-40°.

April 25, 1939 - After rising from 53° at 4 AM to 86° for a few hours in the early afternoon, winds shifted to the northeast mid-afternoon and the temperature dropped back to 52° by 11 PM.  And then, three days later, the high would be only 46° (20 degrees below average).

July 4, 1941 - Just two days after a torrid high/low of 98°/78°, and winds out of the southwest, today was rainy, foggy and cool, with winds from out of the northeast, and a high/low of just 64°/62°.  Today's high would be July 4th's coolest until 1978.

 

Reverse
  

March 22, 1945 - In the midst of the very mild second half of March, today was an outlier as the high reached only 40° (the low was a seasonable 35°).  Winds were out of the northeast, skies were overcast and light showers fell throughout the day. 

April 13, 1955 - A chilly high of 46° came just two days after a high of 84°.  Skies were overcast and winds were from the northeast.

July 6, 1956 - Although yesterday was cool (high/low of 66°/58°), today was even cooler, as the high/low was just 61°/57° under gray skies and winds from out of the northeast.  These two unseasonably cool days followed consecutive days in the 90s.

June 1, 1959 - Today's chilly high of 64°, under mostly overcast skies, followed a five-day warm spell at the end of May that had highs averaging 87°.  Today's conditions were the result of a back-door cold front that moved in from New England last night. 

April 30, 1962 - After three days of summer-like warmth (highs of 91°-89°-80°), and winds from out of the southwest, winds shifted to the northeast after midnight and daytime temperatures were only in the mid-40s. 

April 19, 1964 - The day after the high reached 86°, a "back-door" cold front moved through, and by mid-afternoon the temperature dropped into the mid-50s.  (And on 4/21 the high would be just 44°.)

May 5, 1965 - The day after the high reached 90°, today's was 62°.  Winds were from a north-northeast-easterly direction.

April 28, 1966  - It was a dreary, raw, and damp day, with light rain in the morning.  With a high/low of only 42°/39°, today had the coldest mean temperature of the month.  On 4/26 the mercury dropped from 73° late in the afternoon, to 49° by midnight.  Then the high/low the next two days was 52°/40° and 42°/39°.  Winds were from out of the north-northeast.

April 20, 1972 - The temperature at 4 PM was a quite chilly 43°, a drop of 32 degrees since midnight, and forty-three degrees from yesterday afternoon's 4 PM reading of 86°.  This was a result of winds shifting to the northeast from dawn to dusk.

May 24, 1975 - Today's high of 93° (the Saturday of Memorial Day weekend) was the year's first reading in the 90s.  However, the heat was short lived as a cold front from the northeast moved through during the evening, dropping the temperature to 61° by midnight, and into the upper 50s by the following afternoon. 

 

Overcast

Aug. 11, 1979 - The day following a high of 95°, today's temperatures in the afternoon were only in the mid-60s after the wind shifted to the northeast during the morning.  The next day was equally cool (after a chilly AM low of 57°) - and  a wet one, as 1.68" of rain fell; this was on top of 0.87" of rain that fell the night of 8/11. 

March 29, 1985 - This was the third day in a row with exceedingly mild temperatures, and today was the warmest of the three with a high of 82°.  Then a back-door cold front moved through after dark, and by midnight the temperature was down to 55°, on its way to down to 46° by daybreak on the 30th (but still well above average).  

April 19, 1985 - After the temperature soared to 88°, a back-door cold front moved through during the evening, and the temperature was down to 51° the next morning.  Then the cool air retreated on the 21st, and after two more days with highs in the 80s, winds backed around and came from the east late in the afternoon on the 22nd, cooling the temperature down to 53° by midnight.  

March 30, 1989 - After the wind shifted to the northeast, the temperature fell all day, from 76° to 50°; the next day the high/low was 50°/41°, which wasn't far from seasonable, but it was quite a cool-down from 3/29's high of 82°.

March 14, 1990 - One day after Central Park recorded its earliest 80-degree reading on record, the warm front that delivered this extraordinary warmth retreated south of the area, as winds shifted to the northeast, and by afternoon, under a bank of clouds and fog, temperatures tumbled into the mid-40s, forty degrees colder than yesterday. 

May 23-25, 1992 - It was a Jekyll & Hyde Memorial Day weekend.  Saturday had mid-summer conditions, with a high of 92°.  Then a big change came on Sunday as a strong cold front pushed through in early afternoon, and temperatures plummeted from the low 80s to 45° by midnight.  Monday felt more like October, with overcast skies and a high of just 61°. 

April 12, 1996 - The high reached 80°, and then winds shifted to the northeast late in the afternoon, dropping the temperature to 55° by midnight, and 45° by daybreak on the 13th.

May 10, 2000 - After three days with highs in the 90s, winds shifted from the southwest to the east, bringing in much cooler air, and by daybreak today, the temperature was in the mid-50s, where it stayed for the rest of the day.  

June 12, 2000 - One month after a back-door cold front cooled down a hot spell, it was replicated today, with late afternoon temperatures in the upper 50s, and winds coming from the east-northeast, 24 hours after temperatures were in the low 90s.

 

Northeasterly winds
 

April 16, 2003 - After peaking at 88°, winds shifted to the northeast and by midnight the temperature was down to 51°.  And on the 17th temperatures fell slowly all day, and it was 36° at midnight.  Winds remained out of the east-northeast for the next six days.

May 14, 2004 - The day after the high reached 86°, the temperature was only in the low 60s in the early afternoon.  However, the wind shifted later in the day and temperatures were back into the mid-80s on 5/15.

April 20, 2006 - Today's high of 83° was the warmest reading of the month.  A back-door cold front moved through during the evening, and by midnight the mercury had fallen to the mid-50s, and the mercury was mostly in the 50s for much of the next day, and stuck in the 40s on 4/22 as a developing nor'easter moved up the coast .

April 29, 2009 - The day after the high reached 90° (and dropped 25 degrees by midnight after winds shifted to the north-northeast), the temperature was in the mid-50s by daybreak.

July 19, 2012 - After yesterday's extreme heat (high of 100°) and humidity, today's high, under mostly overcast skies, was just 76°.  Never before has there been such a drop-off in temperature the day following a reading in the triple digits.  The next day the temperature was around 70° during the afternoon. 

May 28, 2014 - One day after a sultry high of 86°, today was overcast, with afternoon temperatures only in the upper 50s.  The back-door cold front passed through after 10 PM, and the temperature quickly dropped into the low 60s, then gradually falling into the 50s by daybreak, where it stayed for the rest of the day. 

June 1, 2015 - After a week of temperatures in the summery mid-80s, today was 30 degrees colder, with periods of rain, drizzle and fog.  Today's high in the 50s was chillier than any day in May - the first time this has ever occurred.  And tomorrow would have similar conditions. 

May 20, 2017 - An early, three-day heat wave came to an end last night after a shift in wind direction.  Today's afternoon temperatures were in the low 60s, which was about 30° cooler than the highs of  the previous three days.

Nov. 4, 2017 - The day after temperatures were in the mid-70s, the temperature at daybreak today was nearly 30 degrees chillier, the result of a shift in the wind direction; afternoon temperatures were twenty degrees cooler.  On the positive side, skies were mostly clear.

April 8, 2019 - After peaking at 79° at 4 PM, winds shifted from west to northeast, and by midnight the temperature was down to 49°.

October 3, 2019 - The day after the mercury soared to 93° (the first reading in the 90s in October since 1941), winds shifted overnight to a northeasterly direction, and temperatures this afternoon were only in the mid-50s.  Light showers and drizzle fell throughout the day.

April 2020 Weather Review: First Cooler Than Average Month of the Year

April 2020

 

April was 2.7 degrees below average, making it the first month this year to be chillier than average.  It was also the fourth chilliest April of the past 40 years.  Even more interesting, this was the first April since 1940 with no highs of 70° or warmer (after three such days in March).  In the years since 2000 the warmest reading in April has averaged 85°, but this April's mildest reading was just 68°.  Despite this cool warmest reading, the nights weren't as cold as might be expected as the coldest reading, 36°, was three degrees milder than a typical April's coldest temperature.  The 32-degree difference between the month's coldest and warmest readings was 20 degrees less than the average difference between the two extremes - the smallest gap of any April on record.

 

The last sixteen days of the month all had below average mean temperatures, the longest below average streak since March 2018's streak of 22 days.  These 16 days were seven degrees below average (seven of the days were ten or more degrees below average).  Before this streak started April had been two degrees milder than average (with April 4-8 seven above average).

 

Although it was the fourth coldest April of the past 40 years, it ranked 63rd among all Aprils going back to 1869.  This was due to the fact that Aprils before 1940 were much chillier.  (Six of the eight Aprils with no high readings of 70° or warmer occurred between 1873-1884.)

 

Cool-ish

 

Although April's rainfall, at 4.49", was an average amount, it was enough to make it the rainiest month so far this year.  The month also had the year's biggest rainstorm - 1.92" on 4/13 (the day after Easter).

 

A typical April is 10 to 11 degrees warmer than March, but April 2020 was just 2.4 degrees milder - the third closest of any year.  Additionally, April's mildest reading was nine degrees cooler than March's (68° vs. 77°) and its mildest low temperature was one degree cooler than March's (53° vs. 54°).

 

Chart - closest april-march temp
 

2020 is just the seventh year in which April, March and February had more precipitation than the month preceding it. This year April had 4.49"; March, 3.78"; February 2.54"; and January 1.93".

When April Isn't Much Warmer Than March

Two.arrows.pointingateachother

 

The month of April is typically 10.5 degrees milder than the month of March.  April 2020, however, was just 2.4 degrees milder, making its average temper the third closest to March of any April (going back to 1869).  The closest April came to March was in 1946 when April was 0.8 degrees milder than March.  The chart below lists the six Aprils that were closest to March's average temperature.

 

Chart - closest april-march temp

And although April 2020 wasn't chillier than March, it had no days in the 70s while March had three (making this the first April since 1940 not to have any readings of 70° or warmer).

Suffering From Post-Snowstorm Depression?

Snowcoveredcar.blizzard2016

 

After the anticipation and euphoria created by a big snowstorm fades, some of us suffer a letdown when the flakes stop piling up (somewhat like postpartum depression).  Drunk from experiencing the fury of Old Man Winter there's hope that another storm will barrel up the coast in a few days - but it's not likely to happen (despite the tendency of the news media to end a weather story by saying, "and another storm is on the horizon").   Looking at more than twenty major snowstorms that have buried New York City in the past 100 years (13 inches or more), no major snowfalls followed in the five days afterward.  The largest accumulation, 2.9", came five days after a 14.5" snowstorm in January 1914; and 2.4" fell four days after the blizzard of January 1996 (before changing to rain).

 

Then there's the matter of snow melt.  New York's biggest snowstorm, in February 2006, has the distinction of having the biggest warm-up in the aftermath of a storm, with three days seeing temperatures rise into the mid-to-upper 50s.  And after January 2016's 26.8" blizzard, the third and fourth days after the storm were completely above freezing.  (The biggest warm-ups after notable snowstorms have all occurred in the 21st century.)  Although there haven't been large accumulations of snow, there have been a number of significant rainstorms in post-storm periods.  The the biggest dumped 1.80" of rain five days after a January 1978 snowstorm (13.6"); 1.49" fell five days after the President's Day blizzard of 2003 (19.8"); and 0.95" fell after a 14-inch snowstorm in the first week of December 2003.

 

Slush.2016blizzard 

 

Finally, although we haven't been burdened by more heavy snowfall immediately following a snowstorm, cold weather in a storm's aftermath has posed a challenge for digging out of some snowstorms.  The coldest period after a snowstorm was the five days that followed the 18.1" snowstorm of Jan. 22-23, 1935, all which had highs colder than 32° (average high/low of these five days was 22/5).  Other snowstorms that had cold weather afterwards include the storms of January 2005 (average high/low of 28/13), December 1960 (30/17), March 1960 (32/19) and December 1947 (32/22).

October's First Autumn Chill

30s

 

I don't know about you, but I find adjusting to the season's first chilly temperatures in the fall a more challenging than adjusting to warm weather in the springtime.  In the fall of 2015 the temperature fell to 35° on the morning of Oct. 19, which was the earliest it was this chilly since 1976, when the low on the same date was 34°.  Mornings in the 30s in October occur infrequently in New York City, with a typical October seeing just two such days.  The average date for the first low in the 30s is Oct. 23.  It's happened as early as Sept. 30 (in 1912) and as late as Nov. 15 (1938).  On average, October's coldest reading is 38°, with the coldest being 28° in 1936.  The mildest chilly reading, 45°, occurred in 1971 and 1946 (more recently, October 2004's chilliest reading was 44°). 

 

The greatest number of lows in the 30s has been nine, in 1925.  One in eight Octobers have had lows of 32° or colder; however, the last time it happened was in 1988 (the coldest temperature in recent years was 33° in 2011).  At the other end of the temperature spectrum, one in four Octobers have had no readings in the 30s (most recently in 2017, 2014 and 2013).  Here are some other observations:

 

  • Two periods have had considerably more 30-degree days than other years.  The years between 1922-1940 averaged 3.9 30-degree days in October.  This followed the years 1910-1921, which averaged only 1.4 such days.  Then there were the years between 1964-1988, which averaged 3.2 chilly lows; since then the average has been half that, 1.6.
  • October 1974 and 1925 were noteworthy for having three days in a row with lows of 32°  or colder.  And October 1940 and 2011 distinguished themselves by having five days in a row with lows in the 30s. 
  • The most consecutive years with Octobers that had no readings below 40° is three: 1994-1995-1996.

  • The second latest date for the first reading in the 30s, Nov. 13, 1946, was sandwiched between two years with the earliest dates for this occurrence - Oct. 1, 1947 and Oct. 4, 1945.
  • After having the earliest temperature in the 30s on record, Sept. 30 in 1912, October had none.
  • Finally, there have been two high temperatures in the 30s in October: on Oct. 26, 1962 (39°) and on Oct. 30, 1925 (38°).

A Trend Towards Fewer Cool Summer Nights (Lows in 50s)

Cool-and-drops

 

In the decades between 1910-1980 the average number of days with morning lows in the 50s during the summer (mid-June thru mid-Sept) was twelve.  Since then the number has fallen sharply, and in the current decade (thru 2019) the average has fallen to 3.4 days.  In 2016, for the first time, there were no lows in the 50s during the summer (1966 had one and six summers have had  two such days, including 2015).  The greatest number occurred in 1940 when there were 33 days.  In recent years the most 50-degree readings was 19 in 1986, and 13 in 2007 (which is the only summer in the past 21 years to have more than 10).  Since 1991 twelve summers have had no lows in the 50s in July or August (including 2014 thru 2019).  There were ten such summers in the years between 1910 and 1990.

Cold, Raw Days of Late May

Grayday.newyork

 

A few weeks ago I published a post about warm weather in May.  Most of us are delighted to get an early start to summer, with days that have temperatures in the 80s and 90s, especially because they aren't usually accompanied by the humidity levels common in mid-summer.  Of course, most Mays have a few cool days in store to remind us that we're still transitioning from spring to summer (May 2015, warmest on record, was an exception).  And raw days in the latter part of May are especially cruel, with summer so close at hand.  This post focuses on these late, cold days.

 

Two dates that stand out on the list below are May 26, 1967 and May 27, 1961.  Both had highs only in the 40s, which is what the typical high is in the second week of March.  The high on May 26, 1967 was 46°, twenty-eight degrees below average; May 27, 1961's high of 47° was twenty-seven degrees below average.

 

One characteristic of chilly days in May is that high temperatures are often significantly more below average than low temperatures.  This is due largely to clouds and rain (and east-northeasterly winds).  Although a typical day in May has a 15-degree difference between its high and low, the chilly days listed below show diurnal variations that are often half that range (seven degrees or less).

Today in New York Weather History: June 15

 

1933

Less than a week after a record high of 97° (6/9), this morning's low of 48° was half that temperature, and also a record.

1971

Showery (0.32" fell) and cool, with a high/low of just 60°/56°.  The high temperature was nineteen degrees below average and more in line with the second week of April.

1974

High temperatures of today and the previous three days: 79° (today)-78°-77°-76°. 

1983

Today's high was 92°, the fourth day in a row with a high in the 90s.

1988

For the second day in a row the high reached 96°.

1989

Overcast skies, AM drizzle, and winds off the ocean resulted in just a three-degree difference between today's high (61°) and low (58°).  The low was five degrees below average, but the high was 19 degrees below the norm.

1994

Today's high reached 96°.  This was the first of four days in the next 30 days with a high of 96° or hotter.

1998

Today was the fifteenth consecutive day with cooler than average temperatures.  During these days high temperatures ranged between 65° and 73° (average is 78°).  This made the first half of June six degrees cooler than average.

2014

Today was Father's Day, and if you forgot to give your Dad a necktie there was no need to fret since the weather was enough of a gift as skies were mostly clear and the afternoon temperature rose to a seasonable 80°.  Today's low of 59° was the third, and last, day with a low in the 50s this month, the fewest since June 1996 (which also had three, all in the first three days of the month). 


Today in New York Weather History: June 13

Rain_delay_mets

 

April 6, June 12, June 13, and November 10 are the dates New York is most likely to have had rainfalls of an inch or more.  Since 1869 it's happened eleven times on these four dates.  June 13 most recently joined this exclusive club, in 2014 when 1.28" of rain fell (see below).

 

1927

It was a beautiful day for the ticker tape parade held in Lower Manhattan to honor Charles Lindbergh after his non-stop flight across the Atlantic Ocean.  Skies were mostly sunny, the humidity was low and the high/low was a seasonable of 77°/60°.

1982

It was a damp and very cool day as 1.65" of rain fell and the high was just 55°, twenty-three degrees below average.  Only three degrees separated the high from the morning low.

1984

I was at the Waverly Theater in Greenwich Village watching Ghostbusters when a fierce thunderstorm struck between 5-6 PM.  (For a while the thunder outside coincided with a scene in the movie with thunder and lightning.)  Before the storm struck it had been a stifling hot afternoon, with a high of 94°.

1989

1.16" of rain poured down in a two-hour period during a thunderstorm in the wee hours of the morning (2-4 AM).  

1998

1.31" of rain fell between 11 AM-1 PM.  It came down especially hard in the second hour when 0.85" fell.  This heavy rainfall followed a steady rain yesterday that amounted to 1.29".

2000

Just two days after a sweltering high of 92°, today's high was an autumn-like 60°.

2013

The day was dreary, cool and wet, with two periods of heavy rain, one in the morning between 9:30 and 11:00 and the second in the evening.  In total, a little more than an inch of rain was measured in Central Park, bringing the month's total rainfall to more than nine inches.  Coming after eight inches of rain fell in May, this was only the seventh time NYC had experienced consecutive months with eight inches or more of precipitation.  

 

Rainyday 

2014

Heavy showers moved thru around 9 AM, and a severe thunderstorm struck between 5:45 and 7:30 PM.  In between, during the afternoon, the sun broke through for the first time in five days.  The 1.28" of rain that fell came one year after 1.26" fell on the same date.

2017

Today was  the third day in a row with temperatures in the 90s, with today being the hottest (high/low of 94°/77°).  However, compared to LaGuardia and Newark Airports, with their respective highs of 101° and 99°, Central Park was in a relative comfort zone.  With today's heat, this became the first year since 1976 to have its first 90-degree days come in back-to-back heat waves (the first heat wave was May 17-19).  Finally, yesterday's and today's lows of 76° and 77° were the first that were 75°+ on these dates in the 1970-2021 period.
