Propelled by an eight-day period between Feb. 18-25, with temperatures that were sixteen degrees above average (high/low of 61/44), February 2017 became the mildest on record. Five days had highs in the 60s and one reached 70° - the earliest 70 in ten years. (This was in stark contrast to two years ago when New York experienced it coldest February since 1934.) There were no Arctic outbreaks; six days had below-average temperatures, in three pairs of two. However, despite the abundance of mild conditions, winter made a jolting cameo appearance on Feb. 9, when the day after the high reached 63°, 9.4" of snow fell during the morning. The day following the snowstorm was the only one with a high of 32° or colder.
The month was 6.3 degrees above average, not much cooler than a typical March. It was also the 20th month in a row that was warmer than average. Of these months, February 2017 had the fourth highest departure from average, behind December 2015 (+13.3 degrees); September 2015 (+6.5) and March 2016 (+6.4).
