Spring begins Tuesday, but winter isn't ready to retire just yet. Two to six inches of rain is forecast over the mountains.
Unlike the snowstorms that passed over ME on March 8 and on March 13 and 14, the approaching storm is not expected to leave behind a large amount of snow.
The winter storm watch, in effect from late Tuesday night through late Wednesday night, also covers southern CT.
As for when the storm arrives, the weather service predicts that the precipitation from the storm will start in southwestern CT and Nantucket around 5 a.m. Wednesday before hitting southeastern MA around 7 or 8 a.m.
Overnight Monday, plow trucks will be staged and ready to treat roads with salt and sand at the beginning of the storm.
Tuesday night: A chance of snow before 3 a.m., then snow likely, possibly mixed with rain and sleet. For both high tides on Wednesday, moderate flooding is expected - that's where the flooding of vulnerable low-lying areas becomes more susceptible to water inundation issues, .
Snow is likely on Wednesday before mixing with rain in the late afternoon.
Snow will also blanket parts of the Ohio Valley and central Appalachians.
Wind gusts from the north-northeast could gusts to 50mph, especially at the coast. Isolated spots could see higher amounts. These really need to be taken with a grain of salt. "It's probably going to be sometime well into April" before springlike weather arrives. "This one will be a tough one to nail down, but we'll get there".
Some meteorologists are optimistic given increased daylight hours, that the sun will be able to prevent snow accumulation from reaching the worst case scenario of 10 inches. Washington is expected to get 4 to 6 inches of snow starting Tuesday, while southern New England is forecast to get 2 to 4 inches.
"These models have had a very hard time trying to figure out how this storm is going to unfold", Dixon said.
NY and the Northeast will greet spring with the fourth nor'easter in three weeks and a blanket of heavy, wet snow from Philadelphia to Boston.
The European model has been the most consistent at keeping the low offshore.
