A storm center moving across Southern New England Monday will focus snow for many, with a change to rain for Southern Connecticut, Rhode Island and Southeast Massachusetts.
Though the snow falls steadily through the day, accumulations will be greatest on grass, cars and other cold surfaces, as the relatively strong April sun - even through clouds - can have enough impact to keep road temperatures warm enough for the treated roads to remain mostly wet, outside of heaviest bursts of snow for some towns during the early to middle afternoon.
For most, snow intensity will begin to wane from northwest to southeast after about 4 to 5 p.m., with about 2-4 inches of accumulation, on average, but local variations, with hilly terrain picking up closer to six inches on the grass.
At the South Coast and Cape Cod, midday and afternoon rain will change to snow before ending overnight. Drier, but still wintry, air will move into New England overnight Monday and Tuesday, providing for clearing sky and cold temperatures with an active wind that will drive overnight lows into the teens with wind chills in the single digits, then make daytime highs in the 30s feel like the 20s at the warmest time of the day.
Wednesday brings increasing clouds with cool temperatures, then night snow in Northern New England that will make for a wintry North Country start Thursday morning.
Farther south, rain is expected Thursday with a spike in temperatures to the upper 50s before a renewed burst of cool air returns with fair weather for the weekend. Next week should level out and quiet down for New England.
