Today in New York Weather History: September 16

 

1903

A category 1 hurricane made landfall on the Jersey shore in the morning and brought a brief period of heavy rain to New York between 11 AM-2 PM, with 1.63" measured.

1971

One week after the last 90-degree day of the year, today had the last 80-degree reading, about two weeks earlier than usual.

1991

Today's steamy high of 91°/low of 72° was 13 degrees above what's typical for mid-September.

1995

From July 24 thru today, a period of of 55 days, just 0.70" of rain was measured.  This was the longest streak of days with less than an inch of rainfall since one of 61 days in Aug./Sept. 1964. 

1999

Tropical storm Floyd flooded the area with 5.02" of rain, forcing many businesses to close early and causing service on some subway lines to be suspended because of track flooding.  Today's rainfall, a record for the date, was comparable to what fell for the entire summer (4.97").  More than half of it fell between 9 AM and 2 PM, but an additional 0.76" fell from a final band of heavy rain that moved through between 8-9 PM. 

Rainfall in Newark and Philadelphia exceeded seven inches.  Floyd produced historic flooding in North Carolina, Virginia, Delaware, eastern Pennsylvania and New Jersey and, at the time, was one of the ten most destructive natural disasters in US history.

2010

A violent and fast-moving storm ripped through the City during the evening rush hour.  While Manhattan was largely spared (0.46" of rain fell), the Brooklyn neighborhood of Park Slope and the Queens neighborhood of Flushing were struck by tornadoes.  I was meeting a friend for dinner and made it to the subway station in my neighborhood 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.

Today in New York Weather History: September 13

 

1889

A dissipating hurricane stalled off the Delmarva Peninsula and brought bands of rain over the course of the past four days, amounting to 4.46", with much of it (3.34") falling yesterday and today.  Except for one hour this afternoon, the temperature was stuck in the 60s.  These four days were the start of streak of nine days in a row (and ten out of eleven) with some rain; total rainfall during this period was around six inches.  (Last September, from the 8th thru the 21st, had rain on eleven of the fourteen days, with nearly seven inches measured in Central Park.)

1904

Although it was just 0.01", today's rain broke a three-week dry spell.  (And nearly four inches  would fall in the next two days.)

1937

It was a very rainy Monday as the biggest rainstorm of the year (and in three years) dumped 3.07" of rain in just ten hours, from daybreak to late afternoon. 

1944

A rapidly intensifying hurricane north of the Bahamas spread heavy rain into the region during late morning and later in the evening.  In total 3.94" of rain poured down, with 2.85" of it falling between 7-11 PM.  This was in addition to 1.64" of rain that fell in the PM hours yesterday from early bands of rain.  The hurricane would move into Carolinas and then the New York region tomorrow afternoon and evening, bringing even more wind and rain.

1952

Today's high of 94° was the hottest temperature so late in the year since 1941 when the high on 10/5 was also 94°.  Today, the last day of a three-day heat wave, was also the last 90-degree reading of the year (in total there were twenty-four 90-degree days this year, well above average).

1970

The first New York City Marathon was held today, a day with wall-to-wall sunshine.  Participants were greeted with a chillier than average morning (58°), which was great for running, and the dew point was in the comfortable 50s.  By afternoon the temperature was slightly warmer than average (80°).

 

First_nyc_marathon

1973

From Aug. 3 thru today, a period of six weeks, just 0.81" of rain fell.  This was the longest streak of days with less than an inch of rainfall since a 45-day streak in Jan/Feb 1968.

1985

The morning low of 49° was the earliest date for a reading in the 40s since 1978 (when it occurred on Sept. 10).

1987

It was a rainy Saturday, which happened to be the wedding day of friends from the City whose reception was held in Westchester County.  Although guests were protected by a sturdy tent, rain trickled in at the edges.  By the time the rain ended in the early afternoon, 1.89" was measured (including 0.80" that fell last night).  Today's rain was the first on this date since 1974.

 

Weddingday

2005

Today's high was 92°, fifteen degrees above average, and the last day of the year with a reading in the 90s.  In total the year had twenty-three such days, five more than average (and quite a jump from last year's two).

2010

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

2018

Overnight showers made this the sixth day in a row with measurable precipitation.  This was the fifth streak of six days or more this year - the greatest number of any year on record.

Today in New York Weather History: September 11

70

 

September 11 is the average date for the last daily minimum temperature in the 70s.  It's happened as early as August 4 (in 1887) and as late as October 10 (in 2018).  Since 2000, the typical year has had 42 days with lows in the 70s/80s (this compares to 32 days in the second half of the 20th century, 27 days in the first half, and 29 days in the 1869-1899 period).

 

1882

Rain from a tropical storm amounted to 3.23", with much of it (2.57") falling today.

1884

This was the eighth unseasonably warm day in a row, all with afternoon highs that ranged from 88° to 91°, and lows that were between 71° and 77°.  The average high/low during this period, 89°/75°, was 14 degrees above average.

1931

The day after the high reached 97°, today's high soared to 99° - both records for the respective dates.  (And in 1983 the same two dates had the same high temperatures.)  This tied Aug. 7 for the year's hottest reading.

 

99

1954

Less than two weeks after Hurricane Carol struck eastern Long Island (Aug. 30-31), Hurricane Edna made itself known, dumping 3.30" of rain, with most of it falling in the twelve hours between midnight and noon.  

1964

This was the third day this month with a high/low of 92°/63°.  The other two occurrences were on 9/4 and 9/9.

1983

Today was the hottest day of the year.  After the day started with an uncomfortable low of 80°, the afternoon high soared to a scorching 99° (the day's low ended up being 78°, occurring shortly before midnight).  This was the highest temperature recorded in September since 1953, when the mercury reached 102° on Sept. 2.  The past nine days were well above average as well (+11 degrees), and included five days in the 90s.  (For some reason I chose this as the day to ride my bike over the Brooklyn Bridge for the first time.)

 

Swelteringheat 

1989

Today, with a high of 91°, was the last 90-degree day of the year.  It was the latest 90-degree day since 1983 (when it occurred on 9/20).  In total, 1989 had sixteen 90-degree days, two shy of the average number.  

1991

Today was the 100th 80-degree high of the year, the first time this threshold was passed in the years since 1970.  (It would later be joined by 2005, 2010, 2015 and 2016.)

1992

The 0.07" of rain that fell between 2-5 AM was the first rainfall on this date since 1978.

2001

After a cold front passed through yesterday evening (producing thunderstorms in the afternoon), today dawned with a bright blue sky.  It provided a surreal backdrop when terrorists crashed two hijacked planes into the twin towers of the World Trade Center.  Winds out of the west/northwest kept much of the smoke billowing from the collapsed towers from blowing north over Manhattan.  The day's high/low was 81°/63°, a few degrees above average.

 

Blueskies_sept11 

2007

Two-thirds of September's rain fell today.  Of the day's 1.21" total, 0.75" of it poured down in a torrential 15-minute downpour between 1:58 and 2:13 PM.  This was the first rainfall on this date in 10 years. 

2009

A coastal storm somewhat resembling a tropical storm buffeted the area with winds that gusted between 30-45 mph and rainfall, which fell throughout the day, that amounted to 0.84".

2013 

It was sunny, hot and humid, with a high of 96° (19 degrees above average).  This was the hottest reading on this date in 30 years, and the latest date for a reading in the 90s since 2005.  The oppressive morning low of 77° made this the 50th day of the year with a low of 70° or warmer, just the eighth year to achieve this since records began in 1869.  (Four more years have joined them since then, with 2020 being the most recent).

Remembering Severe Thunderstorms That Have Struck New York City (1980 - 2020)

Clipart_thstormIn a typical year, 19 thunderstorms strike New York, so that means in the period between 1980 and 2020 more than 700 have rumbled through Central Park   Fortunately, most don't wreak much havoc.  However, the nearly sixty storms described below (in chronological order), or about one or two per year, have caused serious disruptions from their flooding rains and wind damage.  The vast majority have occurred from June through August.  (Inexplicably, the National Weather Service, inexplicably, stopped tracking the number of thunderstorms in Central Park beginning in 1996).   

 

 

July 20, 1982 - During a midday thunderstorm, 0.58" of rain fell mostly between11AM-noon; in a five-minute period at the onset of the storm between 10:57-11:02 AM 0.32" poured down.  This storm snapped a four-day heat wave.

 

July 21, 1983 - Diana Ross' free evening concert in Central Park was interrupted and ultimately postponed when severe thunderstorms lashed the area between 5:30-9PM (2.26" of rain fell, two-thirds of the month's total precipitation).  I'll never forget the sickly yellow-green hue of the clouds as I rushed to the subway after work.  It had also been quite a hot day with a high of 95°, the ninth day of 90-degree weather in the past ten days. (To read more about the Diana Ross concert click here.)

June 13, 1984 - While I was sitting in the Waverly Theater in Greenwich Village watching Ghostbusters a fierce thunderstorm struck between 5-6PM.  For a while the turbulence outside coincided with a scene in the movie that also featured thunder and lightning.  When I returned home afterward I found the entrance to my apartment building blocked by a huge tree branch.  Before this severe storm struck the afternoon was stifling hot, with a high of 94°. 

 

September 3, 1984 - The Labor Day holiday ended with a bang as 0.97" of rain fell in a two-hour period between 8:05-10:05 PM. 

 

June 24, 1985 - During a severe thunderstorm 0.50" of rain poured down in a 15-minute period between 1:50-2:05 PM.  By the time the rain moved out of the area, shortly before 5PM, 0.89" had fallen.

 

August 30, 1985 - It was the Friday of Labor Day weekend and a brief but vicious thunderstorm struck in the middle of the afternoon.  I was walking home after seeing the movie Back to the Future on East 34th St. when the skies opened up.  I sought refuge under the awning of an apartment building in Gramercy Park to escape the torrential downpour that was accompanied by hail and high winds, but it offered little protection so I retreated inside the lobby of the building.  The storm was very brief, about 15 minutes, but it was destructive as many trees in Washington Square Park suffered damage.  It turned out the storm was very localized as areas north of 34th St. weren't hit nearly as hard (Central Park measured just 0.16" of rain).  At the time this was the worst storm I'd experienced in my years living in New York.     

 

Clipart_severe_thstorm2

 

June 21, 1987 - An early morning thunderstorm dumped 1.03" of rain between 3 and 4AM.  Within that hour 0.60" fell in a 15-minute period between 3:18-3:33 AM.

 

July 17-21, 1988 - We experienced very tropical conditions during the past five days with hot temperatures and strong thunderstorms at night that dumped more than five inches of rain.  Tonight's storms produced 1.65" between 6:30PM-midnight. 

 

Clipart_thunderstorm3

 

March 18, 1989 - The temperature nosedived by 40 degrees, from 77° to 37°.  The cold front produced a severe thunderstorm mid-afternoon in which 0.35" of rain poured down in just ten minutes (between 3:14-3:24 PM).  There was also some hail, a rarity in NYC (especially in March).

 

June 6, 1989 - During an afternoon thunderstorm 1.18" of rain fell in just half an hour (1:30-2PM).

 

August 12, 1989 - A number of strong thunderstorms produced three inches of rain (3.50" including rain that fell last night after 10PM).  This was the greatest 24-hour rain total in nearly four years when 3.54" fell during Hurricane Gloria.  At one point 0.43" poured down in just five minutes (12:54-12:59 PM), one inch in fifteen minutes and 1.97" in forty-five minutes (12:45-1:30 PM).   

 

July 21, 1990 - An evening thunderstorm produced 1.11" of rain in just 45 minutes (5:06-5:51 PM).

 

June 3, 1991 - During a nighttime thunderstorm 1.72" of rain poured down in just 45 minutes, from 9:07-9:52 PM.  And in a 15-minute period between 9:23-9:38 PM 0.84" fell. 

 

July 15, 1992 - 0.37" of rain fell in ten minutes during a severe evening thunderstorm (6:37-6:47 PM).  The storm was triggered by a cold front that brought relief after three 90-degree days; today's high was 92°.  The downpour (which dumped 0.89" over three hours) disrupted the opening of the third evening session of the Democratic Convention held at Madison Square Garden. 

 

Thunderstorm_over_manhattan

 

September 3, 1992 - 0.91" of rain fell between 1-2PM.  Rain in the morning and evening added 0.74" more into Central Park's rain gauge. 

 

September 10, 1992 - In just five minutes 0.42" of rain fell between 11:15-11:20 AM, and 1.02" fell in the twenty-minute period between 11:06-11:26 AM.

 

August 16, 1993 - A severe thunderstorm dumped 1.22" of rain in just 30 minutes between 6-6:30PM.  1.81" rain fell during the entirety of the storm.

 

May 25, 1994 - An evening thunderstorm (including hail, a rarity in Manhattan) delayed by three hours my 8:15 flight to Pittsburgh, where I was going to help my family make arrangements for my father's funeral.  I finally arrived shortly before 1AM.

 

August 13, 1994 - 0.48" of rain fell in just ten minutes between 4:20-4:30 PM.

 

August 21, 1994 - During a strong thunderstorm 0.51" of rain fell in just fifteen minutes between 4:15-4:30 PM.  Then between 10PM and midnight an additional 0.52" fell. 

 

May 29, 1995 - During a severe nighttime thunderstorm on Memorial Day 0.50" of rain fell in just 30 minutes (9:40-10:10 PM).  The storm was also accompanied by hail.   

 

June 12, 1995 - In just fifteen minutes a torrential downpour during a thunderstorm dumped 0.68" of rain between 12:28-12:43 AM.  Showers later that afternoon brought the day's rainfall total to 0.99", which accounted for half of the month's precipitation.

 

July 17, 1995 - A torrential rainstorm dumped 3.36" of rain tonight between 10PM-1AM.  Incredibly, 2.09" fell in just one hour (10:19-11:19 PM).  I was attending the theater to see Ralph Fiennes in Macbeth when the skies opened up shortly after intermission.  Soon the rain was falling so heavily that it began dripping onto the stage.  When the play was over many of us hesitated going out into the deluge but theater management wouldn't let us linger.  This was the biggest 24-hour rainstorm since 3.20" fell on Aug. 16-17, 1993.

 

Downpour_nighttime

 

June 13, 1998 - 1.31" of rain fell between 10AM-noon.  It came down especially hard in the second hour when 0.85" fell.  This heavy rainfall followed steady rain that fell yesterday and amounted to 1.29".

 

September 7, 1998 - It was Labor Day and beginning in the afternoon and continuing through the evening severe thunderstorms struck.  0.64" of rain thundered down between 1-2PM and later 1.61" fell between 9PM-1AM.  I was out at Fire Island for the weekend and was on the the beach when the first storm swooped in.  It was truly frightening trying to outrun the storm as it bore down and I thought of Dorothy in the Wizard of Oz as she struggled mightily to get home as the twister approached.  My return to the City was delayed by two hours because train service was suspended.  This was the rainiest 9/7 on record.

 

Storm_approaching_fireisland

 

September 10, 1999 - 0.77" of rain fell between midnight and 1AM.  Total rainfall for the day, 1.38", was a record for the date (and one of the lowest totals to be a daily record).

 

July 14, 2000 - A strong thunderstorm dumped 0.51" of rain in fifteen minutes during lunchtime on Saturday (12:51-1:06 PM).

 

September 10, 2001 - The day was quite warm (a high of 86°, warmest of the month) with a tropical feel to the air.  Then a passing cold front triggered two rounds of strong thunderstorms in the late afternoon and evening which dumped 1.16" of rain.  Later on skies cleared, making for beautiful flying conditions the next morning throughout the Northeast.

 

December 23, 2004 - A strong cold front blew through during the afternoon, producing thunderstorms with 40-50 mph wind gusts.  These storms caused extensive airport delays.  My Christmas flight to Pittsburgh, where I was going to visit my mother, was cancelled, as were many others, and I had to re-book a flight for the following morning.  Today's high of 59° came just three days after a morning low of 11°, the month's two extremes.   

 

March 28, 2005 - My 5:00 flight back to NYC from Pittsburgh after visiting my mother for Easter was delayed by three hours because of heavy rain and thunderstorms in the New York area.  Later, after circling Newark for 20 minutes the flight was diverted to Hartford for refueling and then we quickly got back in the air (I walked into my apartment at 12:15 AM).  2.98" rain fell, a record for the date.  This was the biggest rain producer in six months, since tropical storm Jeanne dumped 4.66" at the end of September.

 

Severe_thunderstorm_warning

 

August 14, 2005 - After a sizzling high of 96° (the fourth day in a row with 90-degree temperatures) a strong thunderstorm dumped 3.11" of rain during the evening.  Two especially heavy periods of rain occurred between 6-7PM when 1.70" fell (including 0.82" in fifteen minutes) and 9-10PM when 0.83" came down.  Today's rain accounted for much of the month's rainfall.  Until today just 0.09" of rain had fallen in the past four weeks.

 

June 2, 2006 - A severe thunderstorm struck shortly after lunchtime on Friday and dumped 1.73" in an hour (2:35-3:35 PM).  During this hour 0.54" fell in five minutes and 1.02" in ten minutes.  My staff and I watched the storm approach from the 36th floor of the office building we worked in at the corner of Park Ave. and 34th St.  Total rainfall for the day was 2.79", a record for the date.  

 

Sept16_2010_storm

 

June 12, 2007 - 0.85" of rain poured down in just 15 minutes between 2:07-2:22 PM. (Topping the 15-minute deluge of 0.68" on this date in 1995).

 

August 8, 2007 - Tremendous thunderstorms moved through New York before daybreak, dumping 2.50" of rain and shutting down much of the City's transit system.  A tornado wreaked havoc in parts of Brooklyn - the first to strike the borough in more than 100 years.  Between 4:36-5:36AM 1.91" of rain came down, the greatest one-hour downpour since July 17, 1995 (when 2.09" fell). 

 

Clipart_funnelcloud

October 11, 2007 - An already gloomy day turned turbulent late in the afternoon as a cold front triggered strong thunderstorms which dumped nearly an inch of rain between 4-5:30.  Rush hour service on the Long Island Railroad was greatly disrupted for a number of hours.  

 

August 18, 2009 - A quick-moving, but severe, thunderstorm struck shortly before 10PM and produced a micro-burst that downed more than 500 trees in Central Park and Riverside Park between West 90th and 106th Streets - the most destructive storm in the history of these storied parks.  0.64" fell during the short-lived storm.  Besides the violent wind and rain the storm was noteworthy for its vivid lightning and booming thunder.

 

MelissaHersh_severeNYCthunderstorm

 

September 16, 2010 - A frighteningly 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.  Service on the Long Island railroad was shut down until the next morning and highway traffic was gridlocked because of downed tree branches. 

 

Cnn_weather_warning_nyc

 

August 9, 2011 - 2.09" of rain fell in the early afternoon, causing extensive subway and street flooding.  I was vacationing out at Fire Island at the time, which escaped the heavy rain.  This was the first of four days this month which saw more than two inches of rain.

 

July 18, 2012 - It was a perfect set-up for wild weather as a cold front met up with very hot and humid air that saw the day's high soar to 100° (with the heat index close to 110°).  This vicious heat was broken by a line of tremendous thunderstorms (with cloud tops at 50,000 feet) between 4-6PM which delivered torrential downpours (1.76" was measured, a record for the date) and hail in lower Manhattan.    

 

April 10, 2013 - What had been a beautiful spring day, with a high of 74°, came to a crashing end as a series of strong thunderstorms barreled through between 7-11PM.  What made these especially noteworthy was the fact that they occurred in early April.  However, despite the storm's long duration, surprisingly little rain fell, with just 0.49" measured in Central Park.  Still, this was the first rainfall of the month.   

 

May 11, 2013 - A strong thunderstorm during mid-afternoon dumped 0.87" of rain between 3-4PM.  Earlier in the day, the morning low of 61° was the first 60-degree low of the year, and was eight degrees milder than average. 

 

May 23, 2013 - Strong thunderstorms between 3-7PM dumped 1.81" of rain.  This brought the month's rainfall to just over seven inches, making it the wettest May since 1990.  It also made it NYC's wettest month since September 2011.

 

June 13, 2014 - Heavy showers moved through around 9AM and then a severe thunderstorm struck between 5:45 and 7:30PM.  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.

 

July 2, 2014 - This was the year's first day in the 90s, the latest date for this occurrence since the summer of 1985.  It was sunny and uncomfortably humid, making the high of 91° feel like 96°.  Some relief arrived after 6:00 when severe thunderstorms with vivid lightning rumbled through the area over the next four hours.  Central Park picked up nearly an inch of rain.

 

July 3, 2014 - Like yesterday, severe thunderstorms moved through in the evening.  Unlike yesterday today's storms didn't feature as much vivid lightning but produced nearly twice as much rain (1.78") in half the time (7:00-9:00).

 

August 31, 2014 - Meteorological summer ended on a hot and sultry note, with a high/low of 90/73.  With dew points in the low 70s, the heat index rose into the mid-90s.  During late afternoon 0.63" of rain fell during a heavy downpour between 4:30 and 5PM.  This was the most rain to fall on the Sunday of Labor Day weekend since 2000. 

 

July 30, 2015 - A series of tropical downpours during the afternoon dumped 1.95" of rain - the first rain to fall on this date in fifteen years.  Today's amount was comparable to the rainfall of the past four weeks and was the biggest rainstorm since Jan. 18 (when 2.10" fell).  During one 20-minute period (between 1:25 and 1:45 PM) nearly an inch of rain poured down.  It was a very muggy day, with dew points in the low 70s and a high of 87°.

 

July 14, 2016 - The air was thick with humidity and the dew point was in the 70s all day.  Although the temperature failed to reach 90° (the high was 88°), the wicked humidity produced heat indexes in the mid-90s.  Some relief came when a strong, but brief, thunderstorm moved through between 4:00 and 4:30 PM, dumping 0.62" of rain in about 15 minutes (winds gusted between 35 and 40 mph).  However, the storm didn't dissipate the humidity as the dew point rose to an unbearable 76° around 7PM.

 

July 31, 2016 - For the third time in this final week of July an inch or more of rain fell.  Much of today's 1.08" (0.77") fell in a five-minute period between 8:39 and 8:44 PM - the greatest five-minute total in the years since 1970.  Today's rain brought July's total to 7.02", making it the rainiest month since April 2014.  And it was also the wettest July since 2009 (when 7.11" fell).

 

June 17-July 7, 2017 - During this three-week period four thunderstorms each produced more than an inch of rain (and 5.27" in total).  On 6/17 a thunderstorm during lunchtime (11:30AM-2PM) dumped 1.39; two days later a thunderstorm during the evening rush hour produced 1.28"; a thunderstorm at daybreak on 6/24 filled the Central Park rain gauge with 1.11", and on 7/7 1.49" poured down late in the morning (10:15 AM thru noon).

 

May 15, 2018 - A very warm and humid afternoon, with a high of 88°, ended turbulently as a quick-moving line of severe thunderstorms struck as the evening rush hour was beginning.  This caused long delays for commuters waiting at Grand Central Station and widespread cancellations for air travelers (like me, trying to return from Pittsburgh).  0.58" poured down in a little more than two hours.  And while wind gusts of 55, 54 and 53 mph were clocked at JFK, LaGuardia and Newark airports, Central Park was protected and a had a peak gust of only 30 mph.  Four persons were killed from falling tree limbs.

July 17, 2018 - A cold front moving into hot and very humid air triggered severe thunderstorms across the metro area in the middle of the afternoon (as well as a funnel cloud over New York Harbor).  In Manhattan nearly two inches of rain fell between 2:30 and 3:30, which exceeded what fell during the first sixteen days of the month.  Before the storm struck the temperature had risen into the upper 80s and the heat index reached 100°.  For the entirety of the storm 2.22" was measured in Central Park, which was three times as much as what Kennedy Airport had, twice as much as Newark received and 40% more than what fell in the rain gauge at LaGuardia. 

 

July 22, 2019 - 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°.  Before the storms arrived the temperature had reached 90°, making this the fourth day in a row with highs in the 90s.

 

July 22, 2020 - Today was the fifth day in a row with high in the 90s (today's high was 92°) and then a severe thunderstorm with lots of lightning and deep rumbles of thunder dumped 1.23" of rain between 7-8 PM.  Winds gusted to 35 mph in Central Park and 45-55 mph gusts were common in the suburbs.

Aug. 12, 2020 - Very tropical conditions brought heat (high of 90°), stifling humidity (the dew point reached 77°, producing a heat index around 100°), and then a severe thunderstorm during the late afternoon.  The 1.76" of rain that poured down (almost all between 4-5 PM) was more than triple the 0.55" that fell last week from tropical storm Isaias.  


Today in New York Weather History: August 9

 

1915

Each of the first nine days of August had some rain, totaling 5.14" (3.75" of it fell on 8/4).

1920

Today had the year's first low in the 70s, the latest date on record for this occurrence (it typically occurs the first week of June).  Not surprisingly, 1920 had the second fewest days with lows of 70+, eight (later tied by 1962), one more than 1874.  This compared to the average number of 30 (in the 50 years before 1920).

1942

4.10" of rain fell between 4 AM-2 PM (with 0.89" falling between 11 AM-noon).  This was a record for the date (which still stands), the biggest rainstorm in four years (since the great 'Long Island Express' hurricane of Sept. 1938), and the first of four days between today and 8/17 to pick up more than an inch of rain (amounting to 8.74"). 

1976

Hurricane Belle approached the area during the day, a Sunday, and made landfall as a Category 1 storm near Jones Beach shortly after midnight.  Nearly four inches of rain fell,  much of it between 10 PM and midnight, when 2.37" poured down.  The 3.94" that fell in total was just shy of the record for the date (4.10" fell in 1942).  This deluge is memorable for me because it happened on the evening my brother and I drove from Pittsburgh to New York for my first visit to the 'Big Apple' - and we were clueless about the storm.  We were alarmed by the sheets of blinding rain as we made our way through northern New Jersey, but fortunately, because the eye was about 100 miles to our east, we were spared any high winds.

1977 

This was the fifth day in a row with a high in the 90s.  Highs during these days were 92°, 93°, 91°, 90° and 90° (today).  The average high of this heat wave, 91.2°, was well below that of the brutal nine-day heat wave in July (97.1°).

1980

Today's high was 95°, the eighth day in a row with a high in the 90s.  The average high/low during these days was 93°/75°, eight degrees above average.  

1991

Three inches of rain fell in a 12-hour period between noon and midnight.  During one of these hours (9:22-10:22 PM), 1.04" poured down.

 

Clipart_master_dog_rain

1996

Lunchtime was a soggy one as 0.82" of rain fell between 1-3 PM.  This was the biggest rainstorm of the month. 

2000

Today's high of 90° was the first 90-degree temperature since June 11.  It was also the last day in the 90s this year.  At the time this was the third greatest gap between the penultimate and the last day in the 90s (now the fifth greatest).  In total, only seven days were in the 90s, well below the average of eighteen.  

2001

Today's high temperature soared to 103°, the hottest reading in NYC since 1977, and the first triple-digit reading in August since 1955.  Only July 9, 1936 and Aug. 7, 1918 had a hotter reading (106° and 104°, respectively, and later joined by a 104° on 7/22 in 2011). 

 

Clipart_sweating_thermometer

2003

During the first nine days of August, 5.42" of rain fell, but then just 0.36" would be measured for the rest of the month.  (The first nine days of August 1915 also had rain on each day, totaling 5.14".)

2011

2.09" of rain fell mostly around lunchtime, causing subway and street flooding.  This was the first of four days this month which saw more than two inches of rain.

2013

The air had a very tropical feel to it, with a heat index of 91° in mid-afternoon.  Under mostly cloudy skies (northern suburbs and southern New England had substantial rainfall), the day's high/low of 85°/74° was four degrees above average - the first day with an above-average mean temperature since 7/23.

1918

In the midst of a five-day heat wave, today's high of 104° was, at the time, the hottest reading on record (later topped during the summer of 1936).  This was the only day of the heat wave to have a high in triple digits.

1924

In the midst of a five-day heat wave, today's high reached 99°, and the heat index approached 110°. 

1955

Every day in the first week of August had temperatures in the 90s (today's high was 93°).  The average high/low during these days was 96°/75°, ten degrees above average.  The heat wave came to an end this evening, when thunderstorms from mid-afternoon onward dropped nearly an inch of rain.

1962

The day's low of 72° was the last low in the 70s this year, the third earliest date on record (after July 31, 1927 and Aug. 4, 1887).  The typical date for the last 70-degree low is during the first week of September.  In total, there were eight days with lows in the seventies this year, tied for second least.  (The typical number during the 1940-1960 period was 28.)

1975

Five days after the hottest temperature of the year (98°), today's high was a chilly 64° under overcast skies.  This was 20 degrees below average - and more typical of a day in late April or the middle of October.

1990

Like yesterday, when 1.90" of rain fell overnight, another rainstorm in the wee hours dumped 1.70" (between midnight thru 5 AM today). 

1994

For the second morning in a row, the low was a chilly 57°, a record for the date, and twelve degrees cooler than what's typical for early August.

1999

Today was the sixteenth day in a row in which the high temperature was 87° or higher.  (Only an eighteen-day streak in the summer of 1988 is longer.)  Twelve of the days had temperatures in the 90s, including eleven in a row between July 23-Aug. 2.  For the entire stretch of days, the average high was 92°, seven degrees hotter than average.

2001

The day was blistering hot as the afternoon temperature soared to 99°.  This happened to be the day the ad agency I worked for at the time, Foote Cone & Belding, held a summer picnic in Central Park.  Most of us spent the time seeking shade.

2003

1.19" of rain fell between 9 PM and 3 AM.  Not only was it the eighth day in a row with some rain, but the first time in ten years that it rained on this date.

2020

Rain that began around daybreak cooled the temperature to below 70° for the first time since July 17.  This 20-day streak was the fourth longest of its kind, just two days shy of the record set in the summers of 1980 and 2010 (and there was a streak of 21 days in 1988).  The mercury dropped to 66°, which was the coolest reading since a low of 65° on June 29. (The day's forecast low had been for the low 70s.)

Today was the thirteenth day in a row with a high temperature of 89° or hotter.  Of these days, eight were in the 90s, including today, which had a high of 95°.  This was one month after an eight-day streak of highs of 88°+.

1960

Three days after 1.50" of rain fell, the biggest rainstorm in five years (since Hurricane Connie) dumped 3.56" in a 12-hour period between 1AM and 1PM.  This heavy rain was produced by tropical storm Brenda, which moved over NYC on its way to New England.  At the time this was the second greatest daily amount in the month of July (it's now ranked third).

1966

Today, with a high of 77°, was the only day this month to have a high cooler than 80° (on average July has six such days).  It was also the first day with a high in the 70s in six weeks, a period in which highs averaged 91°, eight degrees above average.  Twenty-three of the days had highs of 90° or hotter.  Besides the heat, there was very little rain, with just 1.29" measured.

1971

Three inches of rain fell, most of which came down between 6 AM-3 PM.  At its heaviest, 1.04" fell in the hour between 9-10 AM.  Because of the thick cloud cover there was little change in temperature, with the high of 75° just three degrees above the day's low.

1975

With a high of 87°/66°, today was the 14th day this month with a mean temperature at seasonable levels - the most of any month in the 1970-2020 period. 

1988

Today's high topped out at 98°, a record for the date.  Later in the day I escaped the heat by leaving on vacation in the Canadian Rockies (where, four days later, a few inches of snow fell near Lake Louise inside Banff National Park).

2000

The 0.23" of rain that fell today (mostly from a shower in the pre-dawn hours) would be the last time rain fell on this date until 2015.

2006

This was the third day in a row with a high of 89°.

2015

A series of tropical downpours during the afternoon dumped 1.95" of rain - the first rain to fall on this date in fifteen years.  Today's amount was comparable to the rainfall of the past four weeks and was the biggest rainstorm since Jan. 18 (when 2.10" fell).  During one 20-minute period (between 1:25 and 1:45 PM) nearly an inch of rain poured down.  It was a very muggy day, with dew points in the low 70s and a high of 87°.

All of July's rain fell during 11 of the past 15 days, amounting to 4.28".  Nearly an inch of rain fell this afternoon between 3:30 and 4:30 during a strong thunderstorm.  It was also a hot day, with a high of 90°.

1968

There were just three days of measurable rain in July, and today was the third day, which accounted for most of the month's rain as afternoon thunderstorms dumped 2.02", most of which fell between 1:30 and 2:30.  At the time this was a record for the date (later broken in 1997). 

1983

Today's high was a refreshing 76°, the only day this month that didn't have a high of 80° or warmer.  A typical July has six days with afternoon highs cooler than 80° .

1991

Nine of the past ten days had highs in the 90s; four were 99° or hotter.  In addition to today's heat ("only" 90°), a late afternoon thunderstorm dropped 0.39" of rain in an hour (5-6 PM).

1997

The remnants of tropical storm Danny dumped 3.75" of rain, the rainiest 24-hour period on record for the month of July.  (Rain that fell after midnight brought the storm's total rainfall to 4.62".)  Rain was heaviest between 8:21-9:21PM when 0.94" fell.  With winds out of the east-northeast it was also a very cool day; the high/low of 68°/58° was fifteen degrees below average.

Today's high was a record 97°, and the heat index reached 105°.  Late in the afternoon I went to a baseball game on Staten Island to see the farm teams of the Mets (the Brooklyn Cyclones) and Yankees play, and I was drenched in sweat before the game even began.  There was no breeze to speak of.  Even at 11 PM the temperature was a sweltering 88°.

2011

Today was the eighth day of the past nine with a high in the 90s.  And the one day that didn't reach 90° had a high of 89°.  During these nine days the average high was 95° (including 104° on 7/22 and 100° on 7/23).

2020

Due to widespread closures caused by the COVID-19 pandemic, the Mets didn't play their home opener until today.  And although this game was played in mid-summer, it didn't have the warmest reading of any home opener.  Under mostly cloudy skies, the temperature during the game was in the the upper 70s (average high is 84°), which was cooler than home openers in 1977 (90°), 1991 (90°) and 1998 (86°); however, it was on the humid side, with dew points hovering around 70°.  As for the game, the Mets beat Atlanta, 1-0.

1969

An evening thundershower that dropped 0.11" of rain was the first measurable rain on this date since 1952.  Also, with a high/low of 96°/76°, this was the hottest day of the year, based on mean daily temperature.  (Although 5/29 had a high of 97°, its low was two degrees milder than today.)

1983

For the fifth year in a row the temperature rose into the 90s on this date.  This joined another five-year streak from 1936-1940 on July 10 (and later joined joined by streaks in 1990-1994 on July 9 and on July 7 from 2000-2014). 

1988

After a steamy afternoon high of 94°, an inch of rain poured down in a 60-minute period during an early evening thunderstorm between 6:40-7:40 PM.

1995

A torrential rainstorm dumped 3.36" of rain tonight between 10PM-1AM.  Incredibly, 2.09" fell in just one hour (10:19-11:19 PM).  On this night I was attending a performance of Macbeth when the skies opened up shortly after intermission.  Soon, the rain was falling so heavily that it began dripping onto the stage!  When the play was over many of us hesitated going out into the deluge, but theater management wouldn't let us linger.  This was the biggest 24-hour rainstorm since 3.20" fell on Aug. 16-17, 1993.

1996

Today's low of 74° was the warmest low temperature of the year, tying a few dates in 1976 for the distinction as the "coolest" warmest summertime low in the 1970-2021 period.  Another low of 74° would occur on Sept. 10.

1999

The high temperature soared to 98°, and was one of nine days this month with a high of 97° or hotter.

2001

0.50" of rain fell in an hour between 6-7 PM.  This was the biggest rainstorm of the month.

2006

Today's high was 95° after a low of 77°.  The mean temperature of 86° was the warmest of the month.

2009

The afternoon high of 86° was the warmest reading of the month, the coolest July maximum temperature on record.

2018

A cold front moving into hot and very humid air triggered severe thunderstorms across the metro area in the middle of the afternoon (and a funnel cloud formed over New York Harbor).  In Manhattan, nearly two inches of rain fell between 2:30 and 3:30, which exceeded the 1.95" of rain that fell during the first sixteen days of the month.  Before the storm struck, the temperature had risen into the upper 80s and the heat index reached 100°.  For the entirety of the storm, 2.22" was measured in Central Park, which was three times as much as what Kennedy Airport had, twice as much as Newark received and 40% more than what fell in the rain gauge at LaGuardia.  In the past six days nearly four inches of rain fell.

2019

A severe thunderstorm between 8-9 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 0.68", making this the wettest day of the year.  This moisture was from the remnants of what was hurricane Barry, which flooded Louisiana earlier in the week.  This was the second tropical storm named Barry to drench NYC; the first was in June 2007, when nearly four inches of rain fell.

Less than a week after highs of 96° and 97°, today's high on a rainy day was only 67° (more typical of early May).  But a week later broiling heat would return, with back-to-back highs of 100° on 7/21 and 7/22.

1983

The high reached a stifling 98°.  (It appeared this would be the hottest reading of the year, but then on Sept. 11 the mercury soared to 99°.)  This was the day I became an uncle for the first time, as my nephew Corry was born in New Jersey (he shares the birthday with his father).  He'd become used to celebrating his birthday in scorching heat.

1988

A thundershower between 1-2 AM produced 0.14" of rain, the first of twelve days of rain in the next fourteen.  A total of 7.44" of rain would fall in Central Park during this wet two-week period.  Also, today's high of 93° was the eighth 90-degree reading of the past ten days.   

1992

0.37" of rain fell in ten minutes during an evening thunderstorm (7:37-7:47 PM).  The storm was triggered by a cold front that brought relief after three 90-degree days; today's high was 92°.  The downpour (which dumped 0.89" over three hours) disrupted the opening of the third evening session of the Democratic Convention held at Madison Square Garden.

For the third year in a row the high was in the 90s on this date.

1995

This was the hottest day of the summer as the high reached 102° after a low of 84° (the warmest morning low on record).  The high was a record for the date.  This intense heat was produced by the same high pressure system that broiled Chicago for five days and resulted in the deaths of 750 residents.

2014

For the ninth day in a row the low temperature was either 71° or 72°.  (The average during these days is 69°.)  During these nine days there were seven different high temperatures, ranging from 83° to 91°.

2016

Since 2010 there have been 34 days with lows of 79°, and the average high on these days was 96°.  Today's low was also 79°, but, with a high of 88°, it joined July 26, 1979 (high of 87°) as the only two days with lows of 79° or warmer not to have a high in the 90s.
