The 1.3" of snow that fell late in the afternoon brought January's snowfall to 27.4", making it the snowiest January and the second snowiest of any month (now ranked third and eighth, respectively). The month had three significant snowfalls: 11.5" on Jan. 2, seven inches on Jan. 20 and 5.1" on Jan. 27-28. All but 2.2" of the winter's snow fell this month.
The temperature at 9:00 AM was 6°, just eighteen hours after the 3:00 PM temperature on 1/28 had reached 58° - one of the greatest temperature drops in less than 24 hours in NYC history. Winds gusting between 20-30 mph in the morning produced sub-zero wind chills. This incursion of Arctic air was accompanied by the only measurable snowfall of the month, a measly 0.1". This was the fourth January in a row to have less than an inch of snowfall (the average amount back then was close to 10").
With a high/low of 51°/42°, today was the first day completely above freezing in nearly seven weeks (since Dec. 14).
Rain changed to snow around daybreak and the 1.8" that accumulated was not only the first measurable snow of the winter (the latest date on record), but the largest accumulation as well. (Through 2021, this is the last time an inch or more of snow fell on this date.)
Although it was just 1.03", today's rainfall was enough to set a record for the date (breaking the record from 1870). Only three other dates have had less precipitation for their daily record: 0.86" on Sept. 9, 1904; 0.91" on April 29, 1909; and 1.02" on June 8, 1900.
This was the only day between Jan. 3 and Feb. 17 that was completely above freezing (high/low of 42°/35°).
The afternoon high soared to 69°, thirty-one degrees above average, and a record for the date.
In the past four days, very cold and dry air produced 2.5" of powder/fluffy snow from just 0.04" of liquid precipitation. Today was the eighth day this month with measurable snowfall, which was notable since only 4.7" of snow fell during the month.
Today was the fifth day this month to have 0.01" of precipitation, the most of any month in the 1970-2018 era (April 2019 would have also five such days). Today's precipitation was in the form of snow as the high/low was 30°/21°.
