Snowfall was below normal for much of the Northeast in January.

While precipitation was above-normal in many areas, the warmer-than-normal temperatures meant much of that precipitation did not fall as snow. January snowfall ranged from 3 inches to more than 12 inches below normal for a large portion of the region. The largest deficits were found in upstate New York, northeastern Pennsylvania, and portions of northern New England. However, a nor’easter early in the month helped push snow totals above normal for some coastal areas. The greatest snowfall surplus of more than 9 inches was in southeastern Massachusetts. Twenty-six of the region’s 35 major climate sites received below-normal snowfall, with ten ranking this January among their top 20 least snowy. Conversely, of the nine snowier-than-normal sites, five ranked this January among their top 20 snowiest.
