This was the last day of a two-week period with unseasonably cold weather. The average high/low of 32°/21° was ten degrees below average. Eight of the days had highs that were 32° or colder. And there were snowfalls of seven inches and six inches.
A snowfall of 2.7" during the afternoon was produced from 0.15" of liquid, which was the most to fall during what would be the driest December on record (0.25" of precipitation). Today's amount was the most to fall in nearly five weeks (since 11/20, when 0.37" of rain/snow fell).
Snow that began late in the afternoon yesterday continued thru 9:00 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 1-6:00 AM when six inches accumulated. The day's temperatures were well below average, with a high/low of 28°/17°.
The first one-inch snowfall of winter fell between mid-morning thru early afternoon, accumulating 1.8" (the first measurable snow of the winter fell one week earlier on 12/15). It was also a cold day, with a high/low of 32°/23°.
Very similar to 1970, light snow fell throughout the morning and continued until mid-afternoon, accumulating 1.8". This was the first measurable snow of the winter. And at 32°/24°, the day's high/low was nearly identical to 1970's as well.
The first snowfall of the winter fell in the pre-dawn hours, but after 0.6" accumulated it was quickly washed away by heavy rain (about two inches). The temperature rose steadily from 31° to 53°.
In the midst of a frigid December (second coldest on record), today's high of 18°/low of 8° was not only the coldest day of the month - but of the entire year.
After a very mild low of 58° (twenty-eight degrees above average!), the afternoon high inched up by only three degrees.
The 0.14" of cold rain that fell this evening after 8:00 PM was the first precipitation to fall on this date since 1983.
The temperature dropped from a record high of 63° to 22° by midnight. This was the first subfreezing temperature of the season, the latest date for this occurrence on record, breaking the previous 1948 record by eleven days. (Central Park was frost-free for nine months.) Between Nov. 29 and today temperatures were 11 degrees above average.
Today was the first of thirteen days in a row with high temperatures of 32° or colder - one of New York's longest cold streaks on record. During mid-afternoon a quick burst of snow amounted to 0.8".
A high/low of 27°/13° made this the coldest day of the month. (Two days later the temperature would jump into the upper 50s.)
High temperatures over the past six days exhibited a pattern that only a "numbers" geek could appreciate: 36°-36°-37°-37°-38°-38° (today). They were all colder than average (low 40s). And today and yesterday had the same high as well as low (38°/28°), making this the tenth pair with the same high/low this year, tying 1931 for the most in one year.
Just two degrees separated today's high (38°) and low (36°). It was a very blustery day, with 30-40 mph wind gusts, so the wind chill in the 20s gave the air a Christmas-like feel. Still,the day was one degree above average, making it the 16th day in a row with an above average reading. This was also the 15th day this year with a low temperature of 36°, the most of any daily minimum.
On the first full day of winter today's high, despite mostly overcast skies, soared to 71° - eight degrees above the previous record for the date. This was just the ninth time a 70-degree reading was reported in December (the eighth time was in 2006). And the day's low of 61° was milder than the warmest high temperature of five Decembers since 2000. Overall, the day's mean temperature was 30 degrees above average.
