August 2020 Weather Recap: A Continuation of Summer's Above Average Temperatures

Isaias august 2020

 

Like June and July, August was warmer than average, but not to the degree of the two preceding summer months.  It was 1.7 degrees above average and the 23rd hottest August on record.  This followed June, which was 16th hottest (2.3 degrees above average), and July, which was 7th hottest (+3.5 degrees). There were no scorching heat waves, but the number of days with lows in the 70s was above average.  Tropical storm Isaias, which struck on the 4th, was August's weather highlight followed by a thunderstorm on the 12th that was the month's biggest rain maker.  Overall, the month's 5.03" of rain was a touch above average.

 

There were four days in the 90s and six days with highs of 88° or 89°.  Hottest reading of the month was 92°. The two days with the warmest lows (78° on Aug 2 and 77° on Aug 11) failed to have highs of 90+.  There were no heat waves and none of the days in the 90s were back to back.

 

Tropical storm Isaias was largely a wind event, with well under an inch of rain measured.  A gust of close to 50 mph was clocked in Central Park while the area's major airports all had gusts around 70 mph.  By comparison, a severe evening thunderstorm eight days after the tropical storm produced 1.76", more than three times the amount from Isaias (0.55").

 

This was the seventh August in a row with no lows in the 50s (coolest reading was 62°).  There were 19 days with lows in the 70s, which was well above average (13).  Only six Augusts have had more; five others also had 19.  However, the number of days with lows of 75°+ was just slightly more than average, ranking 29th (and tied with six other years).  The fourth longest streak of days with lows of 70+, 20 days, ended on 8/7 (just two shy of the longest streak).

 

Finally, the summer of 2020 was the fourth hottest on record (tied with 1983).  However, it was tied for fourth warmest average low but 18th hottest average high.  Although rainfall was slightly above average it was enough to make 2020 the second wettest of the ten hottest Augusts (just 0.11" behind 1983).

Not All Hurricanes are Katrina - News Media Need to Learn Appropriate Adjectives to Describe Hurricanes

Hurricane-Evacuation-Route-Sign-NHE-9467_300When Hurricane Hermine made landfall along the Florida Panhandle I rolled my eyes when the Huffington Post and Daily Beast described the storm "smashing" into the coast.  As a category 1 hurricane, the verb "smash" was overstating its power just a bit.  But in this day and age of constant hyperbole, the bar for danger has been lowered so much that every dark cloud is reported as being as dangerous as epic hurricanes of the past such as Camille, Hugo or Andrew.  And while the hurricane intensity chart shows the type of mayhem that can result with each category of hurricane, I think it would be helpful to add a column for the news media to provide them with the the appropriate adjectives, as shown below.

Today in New York Weather History: August 27

 

1971

Rain from tropical storm Doria moved in shortly before daybreak and continued through early evening.  Rain fell heaviest between 1-3:00 PM when 1.76" came down.  In total, 4.16" was measured - a record for the date.  Wind gusts of 40-50 mph accompanied the rain.  A second round of rain would dump an additional 1.80" between 1-7:00 AM on Aug. 28.  Rainfall amounts were even greater in New Jersey and southeastern Pennsylvania. 

 

Tropical_storm_doria    

1980

It was hot, hot, HOT, with a blistering high of 97°, sixteen degrees above average.

1987

The 0.39" of rain that fell between 5-6:00 AM was the first measurable rain since Aug. 10.

1989

This was the sixth day this month with a low in the 50s, the most in August in the 1970-2020 period (later tied in 2007). 

1990

Today was the year's last 90-degree day, on par with the average date for this occurrence.  In total, the year had a dozen days in the 90s - well below the average of eighteen days.  Between Aug. 3 and today, twelve days had morning lows of 68° or 69°.

2003

Today's low of 72° was the last 70-degree low of the year, more than two weeks earlier than the average date of Sept. 11 - and just one day later than the earliest date for this occurrence (set in 1975 and later tied in 2009).   

2011

During the evening, wind and rain from Hurricane Irene began lashing the area as it slowly made its way northward from the North Carolina and Virginia coasts.  By midnight 2.88" of rain had fallen - with a lot more to come overnight.  As a precaution, New York's transportation system was shut down at noon and 350,000 residents were evacuated from low-lying areas.

2012

In the late morning a quick-forming thunderstorm dumped a half-inch of rain in just 15 minutes, between 1:23-1:38 PM.

Weather Highlights of the 1950s

50s

 

What weather events/trends characterized the 1950s in New York?  The decade began with the fierce Thanksgiving weekend nor'easter of 1950.  Then four tropical systems affected the area in 1954 and 1955: Carol and Edna in 1954, and Connie and Diane in 1955.  1955 also had a torrid summer, as did 1952.  Then there was the summer of '53 that ended with an unprecedented 12-day heat wave.  Five of the six summers from 1952 thru 1957 had 100-degree readings, the greatest concentration of any decade.  The second half of March 1956 and 1958 experienced harsh winter weather while half of the Decembers during the decade had the coldest and/or snowiest weather of their respective winters. 

 

Regarding precipitation, the only snowstorm of a foot or more came at the end of the '50s when 13.7" fell on Dec. 21-22, 1959.  Finally, an extended period with below-average precipitation began at the beginning of the decade and would continue through the mid-1960s.  (Ironically, the rainiest Halloween and Easter occurred this decade, in 1956 and 1958, respectively.)  What follows, in chronological order, are nearly 100 weather highlights:

 

- 1950-

January 4 - Today's low of 59° is the mildest low temperature ever reported in the month of January, and more typical of the average low in the first week of June.  The high was only seven degrees warmer, but it was a record for the date (which still stands).

January 6 - The high rose into the 60s for the fourth day in a row.  Highs on these days: 60° (1/3)-66°-64°-63° (today).

January 26 - Today's high soared to 72°, the mildest reading ever reported in January (later equaled on Jan. 6, 2007).

February 21 - The morning low of was the coldest reading of the winter.  (The average low during the last week of February is in the upper 20s.)

March 4 - This was the seventh day since Feb. 20 with a low of 12° or colder.  Additionally, eight of the days had highs of 32° or colder.  The average high/low during this 13-day period was 32°/16°, twelve degrees colder than average. 

April 10 - For the fifth day in a row the morning low was 32° or colder.  The average low during these days was 29°, which was twelve degrees below average.

May 27 - With a high of 77° this was last of three days in a row with highs in the 70s.  It was the first time it happened this year and is the deepest into a year of any year since 1940 (thru 2020).

July 31 - Today's high of 94° was the the last reading in the 90s this year, the earliest date for this occurrence since 1934 when it fell on 7/30 (1904 and 1903 also had their last 90 on 7/31).  In total there were only six 90-degree days this summer. 

September 24 - Very chilly conditions, with a high/low of only 53°/43°.  Today's high, 20 degrees below average, was more typical of the second week of November.  Unseasonably chilly days like this in autumn are often caused by nor'easters but today was dry under a mix of sun and clouds.

October 1 - One week after a very chilly high of 53°, today's high was 86° (17 degrees above average).

November 2 - Today's high was a record 83° and was the fourth day in a row of extraordinarily mild weather.  Oct. 30 had a high of 79°, Halloween had a high of 76°, and yesterday had a record high of 84°.  Highs during this four-day period averaged 81°, 22 degrees above average.

November 25 - One of the strongest nor'easters of the 20th century lashed New York on the Saturday after Thanksgiving, with winds as high as 70 mph and 1.58" of rain that fell between 6 AM and 8 PM.  Temperatures dropped steadily during the day, from 59° to 36°.  This storm produced very heavy snowfall in Pennsylvania and the Appalachians, including 27.4" in Pittsburgh (over the course of three days).

December 26 - Although it was just 2.9", the light snow that fell today in the morning and afternoon was the biggest snowfall during the winter of 1950-51.  It was also the coldest day of the winter, with a high/low of 22°/9°.

 

- 1951-

July 27 - Yesterday and today were the hottest days of the year, with both having a high/low of 94°/69°.

October 3 - The afternoon of Bobby Thomson's famed 3-run home run against the Brooklyn Dodgers in the bottom of the 9th inning that gave the New York Giants a come-from-behind win, and the National League pennant, was mostly cloudy with the temperature in the upper 60s.

November 7 - Although today's nor'easter wasn't the biggest rain producer of the year (that honor went to a storm on March 29-30 that brought 2.64"), the 2.01" that fell today poured down in less than six hours between 5:30-11 AM, while March's storm was over the course of 40 hours.  Besides this morning's heavy rain, winds gusted to 40 mph.  (And just four days earlier two inches of rain fell, but over the course of twenty-one hours.)

November 20 - For the second day in a row the high/low was a cold 35°/26° (16 degrees below average).

December 17 - Today's frigid high/low of 20°/8° (22 degrees below average) made this the coldest day of the winter of 1951-52.  Skies were clear.

 

- 1952 -

January 28 - Rain in the morning (when temperatures fell from the low 40s through the 30s) changed to snow early in the afternoon, accumulating 5.8" by early morning the next day - the winter's biggest snowfall.

February 21-26 - High temperatures for this six-day period: 38°-38°-40°-40°-42°-42°.  These readings were slightly below average.

March 9 - The low was 31° for the fifth day in a row (which followed two days that had lows of 32°).

April 2 - For the tenth year in a row measurable precipitation fell on this date - the longest such streak on record.  The amount of rain that fell today (during the late morning) was just 0.09", and was the same amount that fell last year on this date.

April 23 - This was the sixth day in a row with a high of 74° or warmer.  The average high during this streak was 78°, which was 15 degrees above average.

June 26 - Today's high/low was a torrid 100°/81°.  The low was New York's warmest ever recorded in June and the high was the earliest reading in the triple digits (next earliest would come in 1966 on June 27).  This heat came three days after a high/low of 64°/58°.

 

101deg 

 

September 13 - 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 (there were 24 in total).

December 2-3 - The biggest snowfall of the winter of 1952-53 brought 4.5".  It was a sloppy snowfall, with snow changing to rain after 2.3" fell before changing back to snow during the morning of the 3rd when an additional 2.2" accumulated.      

December 28 - Today's high/low of 30°/12° made this the coldest day of the winter.  And there would be just one more day this winter with a sub-freezing high (Feb. 2).

 

- 1953 -

February 2 - Today was the second, and last, day of this mild winter with a sub-freezing high, with a high/low of 29°/14°.  (A typical winter has 18 days with highs of 32° or colder.)  It came the day after the high was 52°.  

March 24 - Today saw the fourth rainstorm of an inch or more in the past three weeks.  It moved in shortly after daybreak and was over by early afternoon.  Half of the day's 1.04" rainfall fell between 11 AM and noon.  At the time, March 1953, with 8.76" of precipitation measured, was the second wettest March on record (it's since fallen to fifth place).

July 18 - This was the second day in a row with a high in the triple digits, the first time with consecutive 100°+ readings since late August 1948, when there were three such days in a row.

July 23 - Heavy rain that fell in the morning hours between 8 AM and 1 PM amounted to 2.41", breaking the previous record amount for the date, from 1938, by 0.01".

August 21 - Today was the first day of a record twelve-day heat wave.  It followed a seven-day heat wave in mid-July.

August 28 - In the midst of a 12-day heat wave, today was the first of six days in a row with highs of 97° or hotter.

September 2 - Today's high of 102° was the hottest reading of the year, and the fourth time the mercury reached triple digits this year - a first (later duplicated in 1966).  This was also just the second time a high of 100+ occurred in September (the first was on Sept. 7, 1881). 

September 4 - Today was the twelfth day in a row with highs in the 90s - New York's lengthiest heat wave on record (a record that still stands).  The average high/low during this torrid streak was 95°/74° - fourteen degrees above average.  Today was also the seventh day in a row with a low of 75° or warmer.

 

Heat_wave

 

November 6 - Three days after the high reached 73°, 2.2" of snow fell - the earliest accumulation of two inches or more on record (4.0" fell at LaGuardia Airport).  The snow began around noon but later changed to rain (the day's high/low was 38°/30°).  This was part of an intense storm system that pummeled the City with 50 mph winds.  

November 20 - Four the fourth day in a row temperatures were very mild and nearly identical, with highs/lows of: 71°/50° today and yesterday, 72°/50° two days ago and 71°/49° on 11/17.  This compares to the average high/low of 53°/41°.

December 14 - This was the ninth day of the past eleven with temperatures ten degrees or more above average (including seven in a row between 12/4-10).  This was also a wet period, with rain falling on eight of the days, totaling 4.25", which accounted for almost all of the month's precipitation.  Today was the rainiest, with 1.46" falling during the morning from a nor'easter that moved in yesterday afternoon (dropping 0.42").  Wind gusts of 35-40 mph were reported.    

 

- 1954 -

January 10-12 - Light snow fell for 39 hours, beginning mid-afternoon on 1/10 and ending in the pre-dawn hours of 1/12.  A total of 8.4" piled up, with 2.2" falling on the 10th, 5.4" accumulating on the 11th, and 0.8" falling on the 12th.  This was the biggest snowfall in five years. 

January 16 - 12.5" of snow fell in the past seven days, with measurable snow falling on six of the days.  After today less than an inch of snow would fall for the rest of the winter.

 

NYCsnow1950s

 

January 18 - The morning low of 7° was the coldest reading of the winter.  

February 15 - Two days after the low was 11°, this afternoon's high soared to 69° under clear skies (31 degrees above average, but four degrees from the record set in 1949).

February 28 - Today's unseasonably mild high/low of 59°/41° was typical of temperatures experienced in the second half of this month.  And at 14 degrees above average, the past two weeks' high/low of 56°/38° was more typical of the first week of April.  No day during this two-week period had a temperature that went below freezing.  (At the time, this February became the mildest on record but has since fallen to eighth.) 

April 22 - This was the third day in a row with identical, beautiful conditions - clear skies with a high of 78° every day (compared to an average high in the low 60s).

July 31 - This was the second day this summer with a high of 100° (the other was on 7/14).  Today, however, had the warmest mean temperature of the year as its low was 77°, compared to 69° on 7/14.

August 31 - Hurricane Carol made landfall on eastern Long Island and brushed the City with gale force winds and 1.71" of rain, which began last night and continued today through late morning.

 

Hurricane carol

 

September 11 - Less than two weeks after Hurricane Carol, Hurricane Edna made itself known, dumping 3.30" of rain, with most of it falling in the twelve hours between midnight and 12-noon.  This was the biggest rainfall of the year. 

October 4 - Today had the third low in the 70s this month, the most ever reported in October.  This was somewhat ironic considering that the year had 18 such days in total, well below the average of 25 days (1920-1950).

 

- 1955 -

February 2 - The biggest snowfall of the winter, 3.6", began shortly after midnight and continued thru mid-afternoon.  The temperature fell throughout the day, from 28° to 10° just before midnight.

February 3 - The morning low of zero degrees was the coldest reading of the winter.  The last time the temperature was this cold was on Jan. 31, 1948.

 

Zerodegrees

 

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

August 6 - With a high of 97°, today was the tenth day in the past three weeks to have a high of 97° or hotter.

August 7 - 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.

August 11-13 - Hurricane Connie flooded New York with 7.11" of rain over the course of 39 hours, with the first band of heavy rain moving through late on 8/11.  Although 8/12 had the most rain (3.62"), the heaviest sustained period of rain occurred on 8/13 from 3-9 AM when 2.50" poured down.  Rain was more of an issue than wind, which gusted between 35 and 45 mph, well below hurricane force.  This was the City's biggest rainstorm since the Great Hurricane of September 1944.  And while this ranks as one of New York's biggest rain totals, LaGuardia Airport picked up five inches more rain than Central Park.

 

Conniehurricane

August 18-19 - Less than a week after the flooding rains from hurricane Connie, another tropical system, Diane, affected the region, but compared to Connie it moved relatively quickly.  The first band of heavy rain moved in late at night on the 18th and by 9 AM on the 19th the rain was over; less than two inches fell but significant flooding resulted since the ground was over-saturated from the large amounts of rain from Connie.  Sustained winds got no higher than 30 mph (but winds gusted to 54 mph at LaGuardia Airport).

August 20 - The fierce heat of the first week of August returned for one last heat wave.  Today's high reached 97°, tomorrow's was 96° and 8/22 had a high of 90°.  Nearly half of the days between July 2 and Aug. 22 had highs in the 90s - and sixteen days had highs of 95° or hotter.  (This followed a cool June.)

August 22 - Today was the 25th, and last day, this summer with a high in the 90s.  All but one of the readings occurred in July and August.  Although there have been 16 summers with more days in the 90s/100s, 1955 has the distinction of having the most days with highs of 95°+, sixteen.  (Today's high, however, was 90°.)

October 4 - Skies were sunny and the temperature in the low 70s when the Brooklyn Dodgers finally won the World Series after eight tries.  And they did it against the Yankees (in seven games), making their championship all the more sweeter.

November 29 - It was a very cold day, with a high/low of only 28°/16°, twenty degrees below average.

December 21 - This was the coldest day of the winter of 1955-56, with a high/low of 18°/5°, twenty-three degrees below average.  This followed what was the second coldest day of the winter, 20°/6°, on 12/20.

December 25 - Every day between Dec. 19 and Jan. 2 had well below average temperatures except for today, which had a high of 51° under mostly sunny skies.

December 29 - The 0.3" of snow that fell this evening was the last precipitation of the month, a month in which  only 0.25" was measured - the smallest amount ever reported in December (a record that still stands), and the third driest month of all time (now ranked fifth).  Additionally, 1955 became just the second year to have three months with less than an inch of precipitation (January and July were the other two months); the other year was 1881. 

 

- 1956 -

January 2 - Temperatures were ten degrees colder than average for the past two weeks.

March 14 - It was a windy, raw and wet day.  The 1.02" of rain that fell, mostly between 5 AM and 2 PM, was a record for the date (which still stands) - besting the old record from 1913 by 0.01". 

March 18 - Less than 48 hours after a snowfall of 6.7" an even bigger storm moved in during the afternoon.  By the time snow stopped falling 24 hours later 11.6" of new snow was on the ground (3.8" of it fell today).  And today's high/low was just 30°/21°, seventeen degrees below average.

 

Snowflakes

 

March 19 - After 3.8" of snow fell yesterday afternoon and evening, an additional 7.8" fell today (thru late afternoon).  Temperatures stayed in the mid-20s all day.  In the past four days 18.3" of snow fell from two storms (6.7" fell on 3/16-17) and temperatures were 15 degrees below average.  By contrast, until four days ago just eight inches of snow had fallen all winter.

March 24 - The 1.2" of snow that fell late this morning brought the month's snowfall above 20" (21.1").  This was the fifth, and last time, that more than twenty inches of snow was reported in March (thru 2020).

March 25 - Today's high/low of 34°/18° was eighteen degrees below average. 

April 3 - This was the 23rd day in a row with colder than average temperatures.  During this streak temperatures were nine degrees below average.

April 8 - Rain from yesterday's nor'easter turned to snow after 4 AM and by late afternoon 4.2" of snow was on the ground - yet the temperature never got lower than 33°.  This was the third significant snowfall in the past four weeks, a period in which 25" of snow fell, an unprecedented amount for so late in the season.  Up until mid-March the winter had seen just eight inches.  Not surprisingly, this snowy period was also cold, with temperatures six degrees below average.

 

Clipart_snowy

 

April 28 - Today's high of 84° was the first time in six months that the temperature rose above 70°.  This was also the latest date for a year's first reading of 70+ in the second half of the century.  And it came just two days after the high was just 47°.

June 14 - With a high/low of 99°/76°, today was the hottest day of the year.  The high was a record for the date, twenty degrees above average.  (This was the first summer since 1951 not to have a reading in the triple digits.)  Today was part of a four-day heat wave that was book-ended by a chilly high/low of 66°/56° on June 10 and 66°/55° on June 20. 

July 2 - With a high of 93°, this was the fourth year in a row in which the high reached the 90s on this date.

July 6 - Although yesterday was cool (high/low of 66°/58°), today was even cooler as the high/low was just 61°/5°7 under gray skies and winds from out of the northeast.  The day's high was 22 degrees below average.

October 8 - On the afternoon that the Yankees' Don Larsen pitched a perfect game in World Series Game 5 against the Brooklyn Dodgers at Yankee Stadium, skies were clear and temperatures were in the seasonable mid-to-upper 60s.

October 31 - 2.41" of rain fell, making this the rainiest Halloween on record (3.30" rain was measured at LaGuardia Airport).  And although the bulk of the rain occurred between 11 AM and 4 PM, when 1.74" was measured, rain was still falling in the evening hours (0.33" was measured between 7-11 PM).  Until today October had received just 1.20" of rain.  This was the biggest rainstorm of the year.

November 1 - The day's low temperature was a summer like 65°, a record for the date and the mildest low reading in the month of November until 1971 (when the low on 11/2 was 67°) and 2015 (66° on 11/6).  Despite the day's mild start the high temperature was only two degrees warmer because of showers and overcast skies.

 

- 1957 -

January 15 - Today's high/low was a frigid 12°/0°, making it the coldest day of the winter.  Light snow moved in after dark and continued until early afternoon on the 16th, accumulating 4.9" (two inches fell today).

January 23 - After the mercury rose to 60° during the morning, the mildest reading of the month, a slap of Arctic air slashed the temperature by 40 degrees by midnight - one of Central Park's biggest temperature drops in the course of a day.  Today was also the sixth day in a row with a high warmer than the day before (starting with a high of 23° on 1/18).

February 1 - A quick-moving snowstorm dumped 6.3" of snow between 2:00 and 11:00 PM. This was the biggest snowfall of the winter.

March 10 - For the fourth day in a row the high was 39° (eight degrees below average); however, every day had a different low temperature.  Today was the only day of the four that had sunny skies.

April 21 - This was the first Easter Sunday since 1871 to have a high in the 80s, and at 85° it was the warmest on record (until 1962).  By contrast, yesterday's and tomorrow's highs were in the mid-60s.

May 14 - I was born today in the pre-dawn hours.  Although temperatures on 5/13 and 5/15 were unseasonably warm (mid-80s), today's temperatures were at seasonable levels.  Rain moved in as evening approached and it fell heavily between 9-11:00 when two inches was measured.  In total 2.55" fell and it was over before midnight (a record amount for the date until 1978).  This rainstorm accounted for two-thirds of the month's rain and was the biggest rainstorm of the year.

July 21 - Today's high reached 100°, making this the fifth summer of the past six to have at least one high in the triple digits - the highest concentration on record.  (Last year was the only year of the six not to reach 100° - its hottest reading was 99°.)  Tomorrow's high would reach 101° and would be the last 100-degree day until 1966.

July 22 - This was the sixth day in a row in which the high was hotter than the day before: 101° (today)-100°-97°-91°-90°-88°-83° (7/16).

December 4 - Snow that started falling late last night continued overnight and after a five-hour break resumed later in the morning and accumulated 8.0".  The flakes came down heaviest between noon and 3 PM when they fell at a rate of an inch per hour.  This was the most snow to fall so early in the season since 1938, when 8.8" piled up on Nov. 24-25.  And it was the first of six snowfalls of four inches or more this winter.

 

- 1958 -

Feb. 8 - Today's high was 32°, the first of twelve days in a row in which the high was 32° or colder (today's high was the "warmest" of the streak).

Feb. 17 - It was a bitterly cold day that saw temperatures stuck in the single digits, largely due to mostly overcast skies.  The high was only 10°, which occurred shortly after midnight; the day's low of was reached 24 hours later, shortly before midnight.  This was the ninth day in a row with high temperatures colder than 30°.

Feb. 20 - Today's high was 33°, the first day since Feb. 7 with a high above freezing.  The twelve days from Feb. 8 thru Feb. 19 had a high/low of 24°/13°, thirteen degrees colder than average.

March 20 - An intense nor'easter brought winds of 35-45 mph along with heavy, wet snow that began shortly before daybreak and continued thru midday on the 21st.  4.7" fell today and 7.1" the following day.  However, today's temperature never got colder than 33°.  Philadelphia also picked up nearly a foot of snow from this storm, which buried parts of eastern and central Pennsylvania and upstate New York with 30 to 40 inches of snow. 

April 6 - 2.19" of rain fell today, making this the rainiest Easter Sunday on record.  Most of the rain fell between 10 AM and 5 PM.

 

Heavy rain

 

June 12 - Today and yesterday had the year's first back-to-back days with highs in the 80s, the latest occurrence in the 1950-2020 period (it happened one day earlier in 1997).

July 2 - Today's high of 93° was the hottest reading of the year (and the fifth year of the past six to reach the 90s on this date).  The last time a year's hottest temperature was this low, or cooler, was in 1927, when the hottest reading was 92°.  (The next time it happened would be just two years later when the year's hottest reading was only 91°.)

July 30-August 3 - High temperatures during this five-day period were: 87°-86°-85°-84°-83°-82°-81°.

August 1-5 - Morning lows during this five-day period were: 67° (on 8/1)-68°-69°-70°-71° (today).

December 11 - With a high of 23°/14° (eighteen degrees below average), today was the coldest day of a 10-day cold wave (between Dec. 7-16) in which every day had a sub-freezing high temperature.  And the day seemed even colder because of overcast skies.

December 16 - This was the tenth day in a row with a sub-freezing high temperature.  During this unprecedented early cold wave the average high/low was 29°/19°, thirteen degrees below average.

December 26 - With a high of 34°/14°, today was the sixteenth day since 11/30 with a mean temperature ten degrees or more colder than average.  This nearly four-week period was nine degrees colder than average.  However, despite the cold just 3.8" of snow fell during this period.

 

- 1959-

February 2 - The morning  low of 7° was the coldest reading of the winter.

February 20 - High temperatures of the past three days: 44° on 2/18, 33° yesterday and 22° today.  And although Feb. 2 had the coldest reading of the winter, today's high/low of 22°/8° produced the coldest mean temperature.

March 12 - A mix of snow and sleet produced the biggest accumulation of snow/ice of the winter, with 5.5" piling up by the time it ended early in the afternoon.  This icy precipitation was blown around by winds that gusted between 30 and 35 mph.

March 22 - Two days after the high reached 71°, afternoon temperatures were in the upper 20s.

June 1 - Today's chilly high of 64°, under mostly overcast skies, followed a five-day warm spell at the end of May that had highs that averaged 87° (13 degrees above average).  Today's conditions were the result of a back-door cold front that moved in from New England last night. 

June 24 - High temperatures over the past five days: 85°-84°-83°-82°-81° (today).

June 29 - Today's high of 97° was the hottest reading of the summer, but tomorrow, with a high/low of 93°/79°, had the hottest mean temperature.

July 20 - This was the rainiest day of the year, with 1.80" of rain measured.  Most of it (1.57") fell during a severe thunderstorm between 4:00 and 5:00 in the afternoon.

July 24 - 11 of the past 14 days had some rain, which amounted 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 the high reaching 90°

August 29 - Today was the end of a two-and-half-week period that had twelve days in the 90s (including today) and an average high/low of 89°/72° (seven degrees above average).  This hot spell, at the time, helped make this the fifth hottest August on record (it's now fallen to fifteenth).

Clipart_summertime 

September 24 - With a high of 89°, this was the third day in a row of summertime heat.  Yesterday's high was 90° and the day before that it was 89°.  The average high this time of year is in the low 70s.  Today's high was a record (which still stands).

September 29 - The 0.02" of rain that fell shortly after midnight from a storm that began late last night (and dropped 0.34" from 11P-midnight) was the first measurable rainfall on this date since 1936.  At the time, this 22-year streak with no rain for a calendar date was the lengthiest on record, later passed by a 25-year streak on Dec. 1 for the years 1943-1967.

September 30 - After one of the hottest Augusts on record the unseasonably warm weather continued in September, which tied Sept. 1931 as the second warmest (it's now tied for fifth).  The month's temperature patterns were divided into three ten-day periods.  The first ten days were eight degrees above average, the middle ten were six below average, and then the last ten days were nine above average.  Today, with a high of 82°/70°, was twelve degrees above average, and the low was what the average high should be.

October 1 - For the fourth day in a row the low temperature was in the 70s at a time of the year when lows are typically in the mid-50s.

October 6 - Under mostly clear skies today's high soared to 88°, twenty degrees above average, as the unseasonable warmth of August and September continued into October.  This was the hottest reading in October since 1941.

October 11 - This was the twenty-first consecutive day with above average temperatures.  During this three-week period temperatures were close to ten degrees above average, with an average high/low of 81°/65° (more like the end of August); twelve days were in the 80s. 

November 18 - Today's high/low of 33°/2°1 made this the coldest day of the month (19 degrees below average).  It would be five weeks before there was a colder day.

December 22 - Snow that began late in the afternoon yesterday continued thru 10 AM today, adding 10.3" to yesterday's 3.4" for a total accumulation of 13.7".  (By contrast, LaGuardia Airport picked up just 5.6".)  Snow fell heaviest between 2-7 AM when six inches accumulated.  The day's temperatures were well below average, with a high/low of 28°/17°.

 

Weather-snowy.landscape 

 

December 23 - Today's high/low of 23°/9° (eighteen degrees below average) made this the coldest day of the winter of 1959-60.

Are Weather Hobbyists Undermining the Credibility of Meteorologists?

CredibilityMy interest in the weather is historical in nature and the posts I publish focus on comparing today's weather conditions with those of past years.  However, many of my fellow weather enthusiasts are interested in the science of meteorology and forecasting.  And while their enthusiasm is heartening I fear they undermine the credibility of trained meteorologists in the public's eye because all too often they build up storms much too early, storms that, more often than not, don't live up to the early hype

 

Amateur forecasters tend to lack the discipline of patience, wanting to be the first to announce a big storm when it's still in the embryonic stage.  Call it a case of  "premature prognostication".   Time and time again, at the earliest indication that a storm is forming they make wild pronouncements about a major snowstorm or hurricane striking a week or more in the future.  And nine times out of ten the storms don't live up to their billing.  So what we have is many boys crying "wolf!", or, rather, "snowstorm!"  Then, maddeningly, after a storm doesn't live up to its hype they're right back at it touting yet another potential blockbuster event that might happen two weeks down the road.

 

Ron.burgundy 

 

But it's not always the hobbyists who come up short.  With more than half a dozen or more competing forecast models available (e.g., European, NAM, GFS, GFDL, NCEP, WRF, and Canadian) even experienced meteorologists risk appearing foolish when they talk publicly about all of the models and their sometime conflicting forecasts.  These models create a Tower of Babel effect.  Whom to believe?  The public doesn't want uncertainty or need to know "how the sausage is made".

Weather Extremes That Occurred Before Global Warming Became a Concern

November1950noreaster
Runway at LaGuardia Airport flooded during the Great Nor'easter of Nov. 1950

Because we're in the grips of global warming, it seems that every weather anomaly is attributed to the rise in temperatures.  However, unusual weather is a regular part of our climate, with ferocious storms and out-of -the-ordinary heat waves not uncommon in years past.  But it's human nature to forget much of what's come before (or, more likely, to be completely unaware of past conditions).  What follows is a list of more than 50 extreme weather events that New York City experienced in the 20th century.  Today they would cause cries of alarm about global warming, but back in the 1930s, '40s and '50s New Yorkers largely accepted what Mother Nature dished out (and without the benefit of air conditioning!).

 

CRAZY WEATHER OF THE 20TH CENTURY

  • 11.63" of rain fell on Oct. 8-9, 1903.
  • An early June heat wave in 1925 (June 4-6) saw highs of 99°-99°-98° (records that are still standing).
  • Fall 1931 was the warmest on record.  (The six warmest autumns occurred more than 50 years ago.)
  • Winter of 1931-32 was the third warmest ever.  (It was the warmest until the 21st century).  On Jan. 14 the high was 70°.
  • Three of the seven warmest Januarys were in the 1930s (1932, 1933 and 1937)
  • NYC's hottest temperature on record, 106°, occurred on July 9 1936.
  • 1938's Great New England Hurricane/Long Island Express struck in late September.
  • There were 90-degree readings in October 1927, 1938, 1939, and 1941 (and the next occurrence wouldn't be until 2019).
  • The Great Atlantic Hurricane of Sept. 1944 was compared to the '38 New England hurricane; it dumped more than nine inches of rain.
  • Unusually mild March of 1945 and 1946; unusually mild October of 1946 and 1947.
  • The City sweltered through torrid summers in 1944, 1949, 1952, 1953, 1955, 1959, 1961 and 1966.
  • Three days in a row in late August 1948 had highs in the triple-digits.
  • The high reached 72° on Jan. 26, 1950.
  • November 1950 featured highs of 84° and 83° at the beginning of the month, and one of the most intense nor'easters on record, on the the Friday/Saturday after Thanksgiving.
  • The City's earliest 100-degree reading occurred on June 26, 1952.
  • Lengthy late August/early September heat waves broiled the City in 1953 and 1973 (at 12 days, 1953's is still the longest streak of 90-degree days on record).
  • A ferocious nor'easter on Nov. 9, 1953, brought 2.2" of snow, and raked the area with 55-70 mph winds.  Two weeks later there was a four-day streak of 70-degree weather.
  • Flooding rains from tropical storms Connie and Diane occurred in August 1955.
  • The Ash Wednesday nor'easter of March 1962, considered one of the most intense storms of the century, pummeled the Jersey shore and the south shore of Long Island and lasted through five high tides.  Although the City escaped heavy precipitation, gale force winds lashed it for three days, with some gusts as high as 50 mph. 
  • A four-year drought in the mid-1950s was followed by a six-year drought from 1961-1966.
  • Huge rainstorms caused flooding and major disruptions for commuters in Sept. 1966 (5.54"), Sept. 1969 (6.28"), Nov. 1972 (5.60") and Nov. 1977 (9.19").
  • Four days in a row in September 1975 had more than an inch of rain, which amounted to nearly 7.50".
  • A mid-April heat wave in 1976 saw the temperature rise to 96° on Easter Sunday.
  • December 1982 and 1984 were both nearly eight degrees milder than average.
  • 75° on Feb. 24, 1985.
  • December 1989 and January 1990 experienced a wild swing in temperature, with the third coldest December on record (10° below average) followed by the second mildest January (10° above average).
  • A high of 85° was reached on March 13, 1990 - 36 degrees above average.
  • "The Perfect Storm" nor'easter of Halloween 1991 was reminiscent of the Ash Wednesday nor'easter of 1962.
  • An intense nor'easter that struck in December 1992 featured 50-mph winds and a storm surge that flooded the FDR Drive and PATH stations in NJ during AM rush hour.
  • The March 1993 Superstorm/Storm of the Century dumped more than 10 inches of snow; heavy sleet was propelled by 50-60 mph winds.
  • The last four days of March 1998 had an unprecedented streak of highs in the low-to-mid 80s.

Today in New York Weather History: June 8

 

1947

Two days after the high reached 87°, today was rainy (0.57") and chilly, with a high of just 56°,  twenty-one degrees below average.  This was the third year in a row in which the first week of June featured very cool readings.

1980

0.51" of rain fell during lunchtime (1-2:00 PM).  This followed a torrential downpour of 0.60" yesterday morning between 5-6:00.

 

Torrential_rain

1992

During an afternoon thunderstorm, 0.41" of rain fell in just five minutes (3:03-3:08 PM).  Overall, 0.77" fell during the entirety of the storm (2:19-3:19 PM).

2005

Today's high was 93°, the first reading in the 90s this year (one day earlier than last year's first 90).

2006

The day was cool (high of 66°) and damp.  The 0.13" of rain that fell between 11 AM-3 PM was the first rain on this date since 1995 (when just 0.01" fell).  

2008

It was a hot day, with a high/low of 93°/74°, fifteen degrees above average.  This was the second day of a four-day heat wave between June 7-10 that saw afternoon highs of: 94°-93°-96°-96°.

 

Clipart_sunnyboy

2013

The 33-hour deluge from tropical storm Andrea ended before daybreak.  In total, 4.77" of rain fell (0.43" this morning), making this the second biggest June rainstorm on record.  Since May 8, 14.49" of rain fell in Central Park, which was ten inches greater than what the normal amount would be. 

 

Tropicalstorm.andrea 

2016

Strong storms moved through during lunchtime, and by the time the rain was over, at around 2:30 (0.42" was measured), the temperature had fallen to 52° - the chilliest reading in two-and-a-half weeks (typical mid-afternoon temperature this time of the year is 77°).  However, by early evening the temperature, although still cool, had recovered to 60°.

Looking Back at New York City Weather: June 7

 

1924

The temperature reached 80° for the first time this year, the latest date on record and six weeks later than the average date for this occurrence.

1925

What a difference one year makes, as today's high was 96°, the fifth day since 6/1 to have a high of 94° or hotter (the outlier was 6/2 which had a high of "only" 88°).  The highs of June 4-7 were all records (99°-99°-98°-96°) - which are still standing.  This is the most intense early June heat wave of all time.  (Highs are typically in the mid-70s during the first week of June.)

 

Flames

1926

One year after the five days between June 3-7 had highs that averaged 97°, the same five days had highs that averaged 65°, ten degrees below average.  And 6/4's low of 48° was a record (that still stands).

1971

Today's high of 93° was the first 90-degree reading of the year, coming a week-and-a-half later than the average date for this occurrence.

 

Clipart_sizzlingsun2

1980

0.60" of rain poured down at daybreak (5-6 AM).

1982

Rain fell for the fourteenth of the past 17 days (and the last eight days in a row), but it amounted to just 0.03" and was done by 4 AM.  The total amount during this period was 3.81". 

1984

Today had the year's first high in the 90s (92°) and was the start of an early heat wave. 

1989

This was the sixth day in a row with declining high temperatures: 91° (6/1)-89°-86°-84°-79°-75°-64° (today).  During these days temperatures went from 16 degrees above average to 13 below.

Downward.trend

1998

Today was the third day in a row with a low of 54° (average for these days is 60°).  This came one month after three days in a row had a low of 55° (between May 4-6).  

1999

Today's high soared to 94°, seventeen degrees above average, and the first 90-degree temperature of the year. 

2000

The morning's low was a chilly 49°, twelve degrees below average.  This is the last time the temperature fell into the 40s in June.

2003

Nearly eight inches of rain fell since May 21, with rain falling on thirteen of the eighteen days.  And every day but one had cooler than average temperatures.  Today's rainfall totaled 0.90" and fell largely between noon-8 PM.  Five more inches would fall this month, which would become the rainiest June on record, with 10.26" measured.

 

Clipart_noahs_ark

2008

This was the fourth year since 1971 to have its first 90-degree temperature on this date.  And like 1999 (one of those four years), the high reached 94°. 

2012

For the fifteenth of the past eighteen days, measurable rain fell in Central Park, including the last seven days in a row.  However, it wasn't a particularly rainy period as six of the days received just 0.01" or 0.02".  Total rainfall during this period was 3.71".

2013

A soaking rain fell throughout the day as the remnants of tropical storm Andrea moved up the coast.  Rain came down especially hard after dark.  In total, 4.16" fell, a record for the date - and the second greatest June rainstorm on record.  This was the second earliest tropical system to affect New York in the 1970-2015 period (now third after Bonnie moved through on Memorial Day 2016); the earliest was tropical storm Barry, which dumped nearly four inches of rain on June 3-4, 2007.  Because of the rain and cloud cover, today's high was only 63°, fourteen degrees below average.

Today in New York Weather History: June 4

 

1895

The day after an early five-day heat wave ended, today's temperature got no higher than 67°, twenty-eight degrees cooler than yesterday's high.

1970

After a summery first three days of the month with highs in the upper 80s, today was gray and raw with temperatures stuck in the 60s, and periods of light rain between 11 AM and 3 PM.  The 0.15" of rain measured in Central Park was the first rain to fall on this date in fifteen years.

1972

Although occurring very early in the month, today's high of 86° would be the warmest reading of the entire month.  By coincidence, 86° was also the warmest temperature in April and May.

1983

For the fourth day in a row, the high temperature was 75°, which was very close to the average high. 

75

1989

This was the beginning of a two-week stretch in which rain fell on ten of the days.  Last year, a similar rainy spell occurred in the second half of July.  This year, 7.28" of rain was measured, while 7.44" fell during last year's soggy fortnight.  Today's rainfall was a minimal 0.09", which fell shortly before daybreak.

2003

2.75" of rain fell, a record for the date.  Shortly before the rain ended, 0.66" fell in the hour between 9-10 PM.  The high temperature was just 57°, nineteen degrees below average.

2007

After beginning the night before, nearly four inches of rain was dumped on the City as the remnants of tropical storm Barry moved through.  The rain was over by noon.  The amount that fell from the storm was double the amount that fell during the entire month of May.

 

Umbrellas

2009

Rain that began late last night continued until daybreak today, amounting to 0.87" (0.54" fell this morning).  This was the fifth year in a row that rain fell on this date.

2012

It was a mostly gray and damp Monday, with a high of just 63° - comparable to the average low of the past two weeks.

Today in New York Weather History: October 29

 

1929 

Wall Street's "Black Tuesday", which presaged the Great Depression, was partly cloudy and chilly with a high/low of 49°/37°, about ten degrees below average.

 

Blacktuesday1929

1971

One day after a high of 77°, today's reached 78°, a record for the date (and 19 degrees above average).  This was the mildest reading since Sept. 16. 

1973

A heavy, all-day rain amounted to 3.67", a record for the date.  Up until today just 0.03" had fallen in October (and it fell twenty-seven days earlier).

1989

Today and the past three days had unseasonably warm high temperatures that were very similar: 77°-76°-77°-76° (today).

2000

Although it was just 0.01", the rain that fell today was the first on this date since 1984 (when just 0.02" fell).

2003

Until yesterday it had been a dry month, with just 1.26" of rainfall measured.  Then 3.62" fell in the past three days, including 1.63" that fell today.

2011

An intense nor'easter lashed the area with high winds and outrageously early snowfall.  The 2.9" of heavy, wet snow that was measured in Central Park was the most ever to fall in October (5.2" fell in Newark and over a foot buried northern NJ, parts of the Hudson valley, Connecticut, western Massachusetts and New Hampshire).  Since the temperature never fell below freezing, there was mostly just slushy accumulation on City streets.  However, the day's low of 33°, which occurred in the early afternoon, was the coldest reading in October since 1988.  Total liquid precipitation from the storm was two inches.  Remarkably, the next measurable snow wouldn't be for another twelve weeks (when 4.3" fell on Jan. 21, 2012).

 

Snow_covered_pumpkin

2012

Unbelievably, an even more devastating storm than last year's nor'easter - hurricane/nor'easter Sandy - struck between noon and midnight.  And it more than lived up to its hype.  Although rain wasn't the issue (less than an inch fell), its 60-80 mph wind gusts and record storm surge wreaked havoc on New York's transportation system and power grid.  Not only did the storm surge strike at high tide, but also during a full moon, resulting in flooding never before experienced in Manhattan.  

 

Sandys_fury

2017

On the five-year anniversary of superstorm Sandy, an intense nor'easter lashed the area with gusty winds and an all-day rain that amounted to 3.03".  This was more rain than fell in the past 60 days, and the biggest rainstorm of the year, passing the rainstorm of 5/2 by 0.01".   

2020

The remnants of hurricane Zeta (which struck the Gulf Coast last night) combined with the energy from a winter storm that struck the southern Rockies and Plains earlier in the week, resulting in rainy and raw conditions in the Mid-Atlantic states.  Rain began here around 7 AM and continued until mid-day on the 30th.  1.53" fell today, 0.64" the next morning.  The rain fell heaviest from 10 AM until 3 PM today, with nearly an inch measured.  After the rain became lighter gusty winds of 25-30 mph moved in.
