New York Weather Highlights of 2010

 2010

 

JANUARY 

30 - With a high/low of 20°/13°, today was the coldest day of the winter.

 

FEBRUARY

6 - It was a very frustrating day for New York snow lovers as a crippling snowstorm that dumped 20-30" in Pittsburgh, DC, Baltimore and Philly stopped at our doorstep, bringing just a few flurries to Central Park.  (Even Staten Island picked up 3-5".)  The culprit was a strong high pressure system over New England that blocked the storm from moving up the coast.  (Despite escaping this storm, Feb. 2010 would become NYC's snowiest month on record, with 36.9".)

10 - Four days after a monster snowstorm stopped short of New York's doorstep, another made its presence known today and dumped 10" of heavy, wet snow.  Because the daytime temperature was just above freezing (the high was 34°) main streets didn't get much in the way of accumulation. 

21 - Today's high of 46° was one of the lowest readings to be the mildest temperature of a winter month.  Despite this chilly mildest reading the coldest reading of the month of 17° wasn't overly frigid.

23 - A cold rain fell throughout the day, totaling 1.20".  Just three degrees separated the day's high/low (38°/35°).  The rain continued until daybreak on the 24th, adding 0.42".

25-26 - After starting in the morning as steady rain, a changeover to snow occurred in the afternoon and developed into New York's third major snowstorm of the winter.  9.4" had fallen by midnight and an additional 11.4" fell the morning of the 26th.  The total precipitation on the 25th amounted to two inches, just two days after 1.42" fell.  The storm's snowfall of 20.9" made this the fourth largest accumulation in NYC history (now ranked fifth) - and just 0.1" shy of the total from the great blizzard of March 1888.  With this storm February's total snowfall reached 36.9", the most ever in any month.    This ended up being the last snowfall of the winter. 

 

MARCH  

13 - On the anniversary of the 1993 March Superstorm, another ferocious nor'easter dumped close to four inches of rain and was accompanied by 50-75 mph wind gusts.  The rainfall was the most in a 24-hour period in March since 1875.  Six persons were killed in the metro area by fallen trees and hundreds of thousands of homes were left without power.

21 - Today, with a high of 64°, was the sixth day in a row with a high that was twelve degrees or more milder than average.  The average high during these days was 68°, seventeen degrees above average.  (Yesterday was the warmest of these days, with a high of 74°.)

30 - The second strong nor'easter in little more than two weeks buffeted the area.  Like the previous one, this storm produced more than four inches of rain.  Beginning late on 3/28 (when 0.34" fell), it continued through this afternoon.  After 1.58" of rain yesterday, an additional 2.45" fell today (a record for the date, breaking the previous record from the nor'easter of 2001).  With today's rainfall the month's total precipitation reached 10.68", making it the wettest March on record.   

 

APRIL

5 - It was a fine spring day for the Mets home opener as the temperature rose into the mid-70s, eighteen degrees above average - the warmest weather for a home opener in nine years.

7 - The afternoon high was 92°, an incredibly hot temperature for so early in the season.  In fact, it was New York's earliest 90-degree reading on record, besting the previous record from 1991 by one day.  This temperature was 34 degrees above average - even in mid-July today's high would have been five degrees hotter than normal.  At 11 PM it was still 80°.  The next 90-degree reading would be seven weeks later, when the high reached 92° on May 26.  

15 - Temperatures in the first half of April were twelve degrees above average, but then the second half of the month would see temperatures closer to normal.  (Average high during the first half of the month was 72° while the second half's average was 63°.)

25 - After just 0.61" of rain fell in the first twenty-four days of the month, 1.60" poured down today.  The rain came from two storm systems.  The first brought the bulk of the rain in the AM hours (1.13"), the second moved in after dark.

 

MAY

May 2 - It was unseasonably warm, with a high/low of 88°/66°, nineteen degrees above average.  Today's high was the warmest since April 7, when the high reached 92°.

May 5 - This was the fifth day in a row with a high in the summer-like 80s (average high during the first week of May is in the upper 60s).  This streak was bookended by highs of 78° on 4/30 and 5/6.

May 9 - A very chilly day with a high of only 52°, seventeen degrees below average.  The morning low of 44° was the chilliest reading on Mother's Day in the 1980-2018 period (Mother's Day 2019 had a low of 43°).

May 26 - Under clear skies the temperature soared to 92°, making this the hottest day of the month.  At 11 PM it was still 85°.  And the full moon was shining beautifully. 

May 29-31 - For the third year in a row no rain fell on any day of the three-day Memorial Day weekend.  High temperatures were warmer each day: 77° on Saturday; 84° on Sunday; 86° on Monday.

 

JUNE

5 - This morning's low was a sultry 76°, sixteen degrees above average.  The afternoon high hit 88°.

6 - Today was the eighth day in a row in which afternoon temperatures rose into the mid-to-upper 80s (but no 90s).  These readings were ten degrees above average.

9 - 0.89" of rain fell, beginning early in the afternoon and continuing until a little past 11PM, breaking a three-week dry spell in which only 0.11" of rain fell.

17 - This was the fifth morning in a row with a low temperature of either 64° or 65° (a few degrees above average).  Today and 6/13's low of 65° book-ended three days with lows of 64°.

24 - Today's high of 92° was the first 90-degree day in a month.  Thirty-three more 90-degree days would occur in the next ten weeks.

27 - It was a hot and sticky Gay Pride Day, with a high of 91°.  And for the seventh of the past eight days the morning low was 71°.  (For more weather highlights from past Gay Pride Days, click here.)  

28 - Today's high/low of 93°/76° made this the hottest day of the month.

29 - This was the tenth day in a row in which the high temperature was 87° or hotter (including four days in the 90s).  All told, half of the days this month were 87°+, helping to make this the warmest June since 1994.  (And a record hot July would follow.) 

 

JULY 

4 - Today's high of 96° tied 2002 and 1999 as the hottest July 4th since I moved to New York in 1979.  It was also the first of sixteen 90-degree days this month, which occurred in a 24-day period between July 4-27.

6 - For the first time since 2001, a triple-digit temperature was reached in Central Park.  Today's high of 103° was the hottest reading since Aug. 9, 2001. 

7 - This was the second day in a row with record-setting triple-digit heat as the mercury climbed to 100°.

23 - This was the ninth year in a row that rain fell on this date; this year 0.70" was measured in Central Park.  And almost all of today's rain fell in a brief period of time as a thunderstorm shortly before 8 PM dumped 0.34" of rain in just five minutes time and 0.60" in 15 minutes.  During the evening the dew point was in the very uncomfortable mid-70s.

25 - Today was the 22nd day in a row with a low of 70° or warmer, tying another such streak in the summer of 1980 as the longest in the years since 1970 (thru 2019).  This summer's streak included nine days with lows of 75°+ and three of 80°+.

29 - Today's low of 74° was the 25th low of 70° or warmer this month, the most of any July (breaking a tie with 1999 and 1908) and the most of any month on record.  These lows were all concentrated in the 26 days between 7/4 and today.  (A typical July in the past 40 years averaged 14 lows in the 70s/80s.)

31 - Today was the second day in a row with a high/low of 85°/66°, and followed another pair of days with the same high/low on July 28-29 (89°/74°).  This was just the third time for back-to-back pairs with the same highs/lows (Aug. 17-20, 1906 and March 3-6, 1952). 

 

AUGUST 

19 - Today was the thirtieth 90-degree day this year, the seventh year in the past thirty with this many hot days.  And there would be seven more 90+ readings in the next three weeks. 

22 - It was dreary and humid with a number of heavy downpours during the afternoon and evening that amounted to 1.69".  (Half of the rain came down in a 90-minute period from 7-8:30 PM). This was the rainiest day since the end of March.  

25 - For the third day of the past four, at least an inch of rain fell; 1.00" fell today, 1.02" on the 23rd and 1.69" the day before that.  Today's fell mostly in the morning.  The amount that fell during these days, 3.71", accounted for 90% of the month's total rainfall.

31 - Today's high of 96° was a fitting way to end New York's hottest summer on record, topping the previous hottest summer, in 1966, by 0.5 degrees.  (Note, this is "meteorological" summer, which is June 1 thru Aug. 31.)

 

SEPTEMBER

1 - September began like August ended, i.e., with a high 96° after a low of 76°.

2 - Today was the fifth day in a row of 90-degree temperatures and the 36th such day this year - thirty of them occurring since July 1.  The morning low was a steamy 78° (fourteen degrees above average), tying 9/6/85 and 9/11/83 for the warmest low temperature in September in the 1980-2019 period.

3 - Hurricane Earl brought only overcast skies and muggy conditions to the New York area but it lashed the eastern end of Long Island.  Then, as a downgraded tropical storm, it made a direct hit on Cape Cod.

8 - Today was the 37th, and last, day of the year with a high temperature in the 90s - two fewer than 1991's and 1993's record number. 

12 - Scattered showers produced 0.15" of rain, breaking a 17-day dry spell. 

13 - This was the third day in a row with a morning low of 59°. 

16 - A violent and fast-moving storm ripped through the City during evening rush hour.  While Manhattan was largely spared (0.46" of rain fell), parts of Staten Island, Brooklyn and Queens were hit by tornadic winds.  I was meeting a friend for dinner and made it to the subway at West 4th St. just as the storm was approaching.  By the time I arrived in Midtown fifteen minutes later, the worst of it was over.  Not until we had finished dinner and walked to Penn Station did we learn of the severity of the storm, as all service on the Long Island Railroad had been shut down for the night.  

25 - Today, with a high/low of 89°/6°7, and the previous three days, averaged 11 degrees warmer than the norm.  This was also the twelfth day this year with a high of 89°, the most on record.

27 - 1.33" rain fell throughout the day, exceeding what fell in the previous four weeks.  One year earlier 1.03" fell on this date.

28 - After a sultry morning low of 70° (fourteen degrees above average), the temperature rose only three more degrees the rest of the day.  This was the 55th day this year with a low of 70°+, which is 50% above average and the second greatest number in the years since 1970 (the year with the most, 2005, had 60). 

30 - 0.75" of rain fell in a 45-minute period just before daybreak (6-6:45 AM).  Overall, 1.10" fell during the morning.  This followed a rainstorm on 9/27-28 that dropped 1.66".  These two rain events accounted for 75% of September's rainfall.

 

OCTOBER 

1- This was the second day in a row with heavy downpours.  One between 5-5:30 AM dumped 1.24". (By coincidence 0.75" fell almost 24 hours earlier between 6-6:45 AM.)  In total 2.46" of rain fell today, and 5.22" over the past five days.

11 - 1.13" of rain fell today, the fourth time in the past nine years more than an inch of rain fell on this date.  It was mostly and evening rainfall, with 0.77" falling between 7:00 and 8:00.  The day's high of 75° was the mildest reading of the month (also reached on 10/27).

27 - After a very mild morning low of 65° (nineteen degrees above average), the afternoon temperature hit a balmy 75°, tying 10/11 as the warmest reading of the month.  Showers fell in the pre-dawn hours and in the middle of the afternoon, amounting to 0.19" - the fifth year in a row that rain fell on this date.

 

DECEMBER 

9 - Today's high of 30° made this the first day of the winter completely below freezing (about a week-and-a-half earlier than normal).

14 - It was a biting cold day, one of the coldest of the entire year, with a high/low of just 23°/19°.  The first snowfall of the winter, just 0.1", fell shortly after midnight.  The last time we had a first snowfall so unsubstantial was ten years earlier.    

22 - The past six days had three pairs of days with the same high temperatures, with each pair warming by one degree: 36°-36°-37°-37°-38°-38° (today).  And today and yesterday had the same high as well as low (38°/28°), making this the tenth pair with the same high/low this year, tying 1931 for the most in one year.

25 - It was calm and cold (high 32°/low 25°) the day before a blizzard moved up the coast, a storm that seemed to come out of nowhere.   

26-27 - Snow began falling during the afternoon of the 26th and by evening blizzard conditions had developed.  When the flakes stopped flying the following morning, 20 inches had piled up.  The City was largely unprepared for a storm of this great a magnitude (and mayor Bloomberg was on vacation at an undisclosed location).  This was New York's sixth biggest snowstorm in its history.  And it was the second 20-inch accumulation of the year - the only year to have that distinction (the first was on Feb. 25-26 when 20.9" fell). 

Although yesterday's 12.2" of snow wasn't a record for the date (the blizzard shared the date with New York's great 1947 snowstorm), today's 7.8" was.  The blizzard's bull's-eye was west of New York where most towns in New Jersey were buried by more than two feet of snow (e.g., Newark measured 24.2").  This was also the 103rd, and last, day of precipitation for the year, tying 1965 for the fewest days in the years since 1950.  The average number of such days is 122.

28 - I was visiting my mother in Pittsburgh for Christmas, which was unaffected by the blizzard in the Mid-Atlantic.  However, I felt its impact today, when I was scheduled to fly back to New York, as most flights were still cancelled and mine was no exception.  However, Jet Blue chartered a luxury bus to JFK Airport.  The trip took eight hours but at least I got back home on the day I was supposed to (albeit at 1 AM).

I find it immensely difficult to believe that November's weather was so uneventful that there was nothing to write about! there had to have been something worth mentioning.

Rob

Ha-ha - believe it! Although 2010 was an eventful year for snowfall and summer heat, the weather took a break in November, with no extremes of cold, warmth, rain or snow. It was a month that just went through the motions.

William

How was this the hottest summer on record despite two other years having more 90° days than this year and three other years having more lows in the 70s/80s than this year?

Rob

I think the best way for you to gain an understanding of how this could happen is to look at the day-by-day temperatures of the summers you mentioned.
