The first time a high temperature reached 70° in December occurred today. It's happened nine times since then (most recently in 2015). It followed by one week a mid-winter-like high/low of 34°/19°.
In the three weeks between Nov. 30 and Dec. 20, today's high of 50° (six degrees above average) was the only one that occurred twice. During these days the highs ranged between 27° and 70°.
With a high of 32°, today was the first day of the winter with a maximum temperature of 32° or colder. The high was reached early in the day and then the mercury fell all day, reaching a low of 15° by midnight.
For the fourth day in a row the morning low was 28°.
Just two degrees separated today's morning low of 45° and the afternoon high of 47°. This tiny diurnal variation was largely due to overcast skies and light rain that fell during much of the day (0.41" was measured).
There was only a three-degree variation between today's high and low of 40°/37°.
Although the temperature fell to 33° on Oct. 29 and 30 (during the Northeast's freak snowstorm), Central Park's first freezing temperature of the season didn't occur until shortly before midnight when the temperature dropped to 32°. This was the latest date for the first freeze in ten years (when it occurred on Dec. 16) and the fourth latest on record.
This was the fourth day in a row with gloomy, raw and damp conditions.
1.4" of snow fell during the morning, the most to ever fall on this date. This was the first snowfall of one inch or more this winter, a little more than two weeks ahead of the average date for this occurrence.
Like last year, the first snowfall of one-inch or more arrived today, accumulating 1.0". Snow showers that moved in during the afternoon began accumulating in the evening when the temperature fell to 32°. This snow was wraparound precipitation from yesterday's nor'easter.
