Arrives a Month Late Winter officially began on December 21st, however it wasn’t until January 20th that the first seasonably cold conditions and (light) snow arrived. The first nineteen days of January averaged a remarkable 11 degrees above normal with one record high achieved on January 6th (69 degrees). Still, winter’s delay would not become a denial. A mid-month jet stream pattern change begin a parade of cold fronts our way, and the character of our weather quickly turned to below normal conditions. The last ten days of January averaged 4 degrees below normal, and the low temperature of 9 degrees on January 26th was the coldest reading since December 2005. In terms of snow, the first thin coating (0.2”)
arrived on January 21st and another half to one inch fell on the 25th.
In aggregate, this small accumulation was seven inches below the January
average. But significant snowfall remains a likelihood
in February, which is historically the snowiest month in the ************************************************************************ STAT OF THE MONTH

Normal high/low temperatures range from 39/21 during the first week of the month to 45/26 by month’s end. The record high for February is 78 degrees (25th in 1930) and the record low is –17 F (7th in 1935). Normal liquid precipitation (rain and melted snow) is 2.47 inches. Average snowfall for the month is about 8.2 inches. ************************************************************************ FEBRUARY OUTLOOK
The coldest weather of the winter is on tap for the first ten days of February as deep northwest flow delivers multiple shots of Arctic air into the Northeast. Given the dominance of this pattern, there’s little chance of meaningful precipitation outside of lake effect snows and snow showers with each passing Arctic front. Temperatures the first ten days of the month will average 10 to 15 degrees below normal, making for the coldest week in over two years. The week of February 10 – 17th holds some promise for a couple of storm threats. Arctic air will relax its grip on the Northeast, while a return of Pacific energy begins a push across the southern US. Timing is everything in creating a good snowstorm, however, I believe the cards will be on table. Temperatures during this mid-month period will likely return to near normal, and that’s still cold enough for snow and ice given a storm track along the east coast. Beyond that, I believe a cold temperature bias will continue
through month’s end, although at nowhere near the magnitude of early
month. When it’s all said and done, this will likely be the coldest
February since 2003. February is historically the snowiest month of the year in
