Today in New York Weather History: January 11



In the past three weeks (since Dec. 22) the average high/low was 31°/19° (seven degrees below average).  Twelve days had highs of 32° or colder (the coldest was 19° on Dec. 27), and thirteen had lows in the teens (coldest temperature was 12° on Jan. 7).  Despite the cold just 4.4" of snow fell (the most was 2.9" on Dec. 30).


Old man winter


It was a cold, snowy day, with a high/low of 24°/11° and an accumulation of 5.4".  Today's snow was part of an 8.6" snowfall that began yesterday afternoon and would end in the early morning hours of 1/12.  This was the biggest snowfall in five years.


5.7" of snow accumulated during the afternoon/evening before changing to rain overnight as temperatures rose into the mid-30s (close to an inch of rain fell).  Despite the changeover, this was a record amount of snow for the date.





Today's 0.2" of snow was the first measurable snow of the winter, the latest occurrence since the winter of 1972-73.  It was also the only snow to fall in January.  (11.8'' would fall for the entire winter.)


The past nine days, all which had sub-freezing high temperatures, were 12 degrees colder than average (high of 25°/ low of 14°).


The biggest snowfall of the winter, 3.5", fell in a three-hour period between 3-6 AM.  (Just ten inches fell for the entire winter - nearly 66 inches less than the previous winter.)


While most of eastern Canada was paralyzed by an epic six-day ice storm, New York was basking in very mild weather.  During the past nine days temperatures were 18 degrees above average.  Average high/low during these days was 57°/43°, typical of the first week in April.




0.54" of rain fell between 2:11-3:11 PM.  Including rain that fell in the pre-dawn hours, 1.29" fell in total.


The first precipitation of the year fell today, a steady rain that fell between noon and midnight, amounting to 0.55".  In the years since 1900, this is the latest date for a year's first measurable precipitation (1963 also had its first measurable precipitation on this date).


The mercury soared to 69°, easily breaking the previous record from 1975 by six degrees.  Today's high was twice as warm as two days ago (34°) and was the warmest reading in January since a high of 72° on Jan. 6, 2007 (like today, it was also a Saturday).  Today's reading was 31 degrees above average, the most above average for a daily high since Feb. 21, 2018's high of 78° (35 degrees above average).  Today's high/low of 69°/51° was more typical of the temperature split on May 5.  Lastly, after rising to 60° at around 9 AM, the temperature stayed in the 60s for the rest of the day.
