Today in New York Weather History: December 20



Ten inches of heavy snow piled up after precipitation started as rain.  As the temperature dropped below freezing (from a high of 36°) it changed over to snow.  Total liquid precipitation for the day was 1.92".  (Both amounts are records for the date that are still standing.)


The day before the winter solstice began would be the coldest day of this winter as the high/low was only 7°/-3°.  Feb. 11 (1885) would come close with a high/low of 11°/-2°. 


Today's rainfall of 1.34" made 1903 New York's wettest year on record, passing 1889 (which had 57.16").  This would remain New York's wettest year until 1972 (it's since fallen to eleventh place).


Today's rainstorm was the third in the past three weeks to produce more than an inch of rain, and the sixth with more than half-an-inch.  Beginning last night, more than half of the 2.08" that fell poured down between midnight and 3:00 AM today.  In total, seven inches of rain fell during these three weeks, making this, at the time, the wettest December on record (it's now ranked third).




Today's high was a teeth chattering 25°, seventeen degrees colder than average.  It was the first high of freezing or below of the season. 


This was the 22nd consecutive day with no measurable precipitation.  This dry spell began at the end of November, a month in which 8.90" of rain fell.  December would end with just 1.13" of precipitation.


Brrr, today's high/low of 21°/11° was twenty degrees colder than average and the coldest day of the month.  (The temperature had fallen from 47° yesterday afternoon.)  This was the coldest day in December in eleven years, since a high/low of 20°/10° on Dec. 27, 1993.  It was also the first day this winter to be completely below freezing.  Additionally, 0.5" of snow fell in the wee hours of the morning.



It was a cold day under slate gray skies, with just three degrees separating the high and low (33°/30°).


Light rain moved in during the evening, making this the record-setting 153rd day this year with measurable precipitation, breaking a tie with 1996.  And there would be five more days of precipitation (all rain) before the end of the year (which amounted to nearly four inches).
