March nor'easter:

A powerful, late-season winter storm is expected to bring more than a foot of snow to parts of Massachusetts through Wednesday, impacting the region with heavy, wet snow, strong winds, and possible power outages.

The National Weather Service said Tuesday that high terrain areas in the state, like the northern Worcester Hills and the Berkshires, could see 1-2 feet of accumulation. Lower elevations are expected to see lesser totals, with rain changing to wet snow accompanied by strong winds, which could make for difficult travel Tuesday afternoon and evening. 

“Snow will continue this evening before winding down overnight,” the service said. “Even portions of the Cape/South coast may see a few inches of wet snow before everything winds down.”


Meteorologists are forecasting that western and central parts of Massachusetts could see 18 inches of accumulation from the storm, but the service said Tuesday that uncertainty about exactly how much snow will accumulate remains high. 

Below, see what the National Weather Service is forecasting Massachusetts may see with the storm — ranging from the highest to lowest to expected potential snowfall accumulations.
