In the years since 1950, January 7 is the date most likely to have had a snowfall of an inch or more in Central Park. It's happened in eleven winters (most recently in 2017). The second and third most likely dates to have one-inch+ snowfalls are February 14 (in nine years) and January 26 (in eight years).
The 3.14" of rain that fell today would be the greatest daily rainfall in January for more than 100 years (until 1979). It was also a mild day, with a high of 56°.
The two inches of snow that fell today, from mid-morning thru mid-afternoon, was the first time an inch or more of snow fell on Jan. 7. (Almost all of the other dates between Dec. 1 and March 31 had their first snowfalls of an inch+ in the 18th century.) Temperatures were quite cold, but rose very slowly through the day, from 17° to 25° shortly before midnight.
This is one of a handful of days that have had just a one-degree difference between the high and low. (36°/35°).
Five inches of snow fell overnight. This accounted for almost all of the month's precipitation of 0.58" - the driest January on record (and, fascinatingly, the same amount that was reported in December).
This was the sixth day in a row in which the mean temperature was 10 degrees or more above average.
It was a frustrating day for snow lovers. Although today's high was only 28°, most of the 0.53" of precipitation that fell came down as freezing rain (0.9" of sleet/snow was measured at Central Park.) This was the worst ice storm in New York since December 1974. (Fortunately, the City's wires for electricity, telephones and cable TV are largely underground.) Freezing rain and sleet were an unusually common occurrence this winter and fell on nineteen days between January 3 and March 10.
A crippling blizzard began Sunday afternoon and continued until noon the following day. It immobilized an area from West Virginia through Massachusetts and dumped 20.2" on Central Park, at the time the third greatest snow total in NYC history (13.6" fell today and 6.6" the next day, both records for the date). At one point five inches fell between 5-7:00 PM. Besides the snow and wind, it was also quite cold, with a high/low of 22°/12°. (For a more in-depth account of the storm click here.)
The first snow of the winter fell today, a light snow that accumulated 0.5" during the afternoon. This was the fourth winter of the past eight in which the first measurable snow didn't occur until January (average date is Dec. 14).
For the third year of the past four the year's first reading of 60° or milder happened in the first week of the year, a month earlier than average. (The other year's first 60+, in 2006, was on 1/9.)
The morning low of +4°, the coldest reading in New York in 10 years, was fifty-one degrees colder than the temperature 24 hours earlier. Wind chill values were in the -10° to -20° range. And although the day's official high of 19° was reached just after midnight, the temperature in the afternoon was in the single digits, thirty degrees colder than average.
It was a very wintry day as snow fell from 10 AM to 8 PM, accumulating 5.1", with the temperature hovering around 20°.
Today, with a frigid high/low of 18°/5°, was the thirteenth day in a row with a high below 32°. This tied it with another 13-day streak during the winter of of 2001 for second longest (in the years since 1900). This winter's streak, however, had much colder temperatures, with an average high of 22°/13° (sixteen degrees below average) versus 30°/19° for the 2001 streak (which also started in December and ended in January).
