A nor'easter produced 3.03" of rain, a record amount for the date - and the most to fall in one day in the month of December (3.25" fell for the entirety of the storm). Rain fell for the entire day, but the most significant amounts fell after 11 AM; more than half of the rain fell between 7-11 PM.
The biggest snowfall of the winter began late in the afternoon, and by the time the snow ended in the early hours of Dec. 14, 9.5" had accumulated (eight inches fell today). The temperature rose into the mid-30s as midnight approached making it a very wet snow, with rain mixed in at times. (Between today and 1/11 there would be an inch or more of snow on the ground in Central Park.) This was the third year in a row to have a significant snowfall in mid-December.
The biggest rainstorm of the year produced 3.03" (2.97" of it fell today), edging out the 2.96" that fell on Feb. 7. The precipitation began, briefly, as snow and sleet as temperatures were in the upper 20s before 7 AM (0.3" accumulated), but the mercury rose into the mid-40s by nightfall. Most of the rain fell between 3 PM and midnight, with one inch falling between 6-8 PM.
The 4.2" of snow that fell this evening was the last time an inch or more of snow fell on this date. The temperature fell throughout the day, from 39° to 22° just before midnight.
Today, with a high/low of 38°/32°, was the 32nd day in the past six weeks (beginning Nov. 2) to have a diurnal variation of less than ten degrees. During these days the average variation was eight degrees. The average high/low of 47°/39° was a few degrees below average.
A breeze out of the northeast, low clouds and periods of drizzle kept the temperature from moving much as just two degree separated the high (40°) and low (38°).
The first snow of the season fell, a dusting of 0.3". It was the only snow to fall in December, and for the rest of the winter just 7.8" more would fall. This was the fourth day in a row of very cold temperatures, with today's high reaching just 29° after a low of 16°.
Rain fell for forty-nine of the past fifty-six hours (between 8 PM on 12/10 thru 5 AM today), amounting to 3.31".
This was the fourth day in a row with a morning low of 33°.
In the two weeks ending today, no two days had the same high temperature. They ranged between 34° and 63°.
Today's rainfall of 0.95" brought the year's total precipitation to more than fifty inches for an unprecedented seventh year in a row.
Today's high (67°) and low (55°) both set warm temperature records for the date. And for the second day in a row the day's mean temperature was 23 degrees above average.
With a high/low of 31°/20°, today had the winter's first high of 32° or colder, five days earlier than average (based on the years since 1980). Last year it occurred on 12/16, and on 1/5 the previous winter. This came four days after the first measurable snowfall (4.6"). At daybreak the wind chill was in the single digits.
Inconsequential snow showers during the daylight hours this morning (the temperature was above freezing) and light drizzle/mist in the afternoon amounted to 0.03", ending a 10-day streak with no measurable precipitation. Although that's not very lengthy, it was the longest streak in this wet year (and the longest since an 18-day streak in Sept/Oct of last year).
