Much of the Northeast received near- to below-normal snowfall from April 1-15, with portions of northern New England and northeastern New York being the main exceptions.

Even though precipitation has generally been above normal, warmer-than-normal temperatures meant most precipitation fell as rain. Snowfall during the first half of April has ranged from 4 inches below normal to more than 6 inches above normal. The largest deficits were found in northern Maine and east of Lake Ontario in New York, while the largest surpluses were found in southern Maine, much of New Hampshire, and parts of eastern Vermont. Of the 35 major climate sites, 28 sites received below-normal snowfall, two received normal snowfall, and five received above-normal snowfall.
