A quick-moving and potent nor'easter will slide by south of the 40N/70W benchmark Wednesday morning. This means most of the damaging winds and rough surf stay farther offshore.
Most of the heavy rainfalls across the southeastern corner of New England. Cape Cod and the islands look to get wind gusts of 40-50 mph from the northeast to north Wednesday morning, with heavy rain around 1-1.5 inch of accumulation.
Boston to Providence to Worcester may see around half an inch of rainfall and northeast, north wind gusts around 30 mph.
In-depth news coverage of the Greater Boston Area.
Wet snowflakes will mix into the rain across much of southern New England, but mostly across higher elevations around dawn. We have plenty of upward vertical motion plus rain-cooled air that can flip the rain to snow, and this occurs before the sun comes up and when we hit our coolest temperatures of the day with lows in the 30s.
Boston and most of southern New England could see scattered coatings of snow accumulation early in the morning on grassy areas. A coating to 2 inches is possible across the Berkshires, Worcester Hills, and southern New Hampshire. This snow won't last long at all once the sun rises and temps warm. Two to four inches of snow is likely through Wednesday afternoon across Maine. Then upslope snow lingers as our wind turns west Wednesday afternoon across the Green and White Mountains.
Wednesday afternoon will feel like a completely different season, with highs around 60 degrees and sunshine. West winds pick up to gusts between 40 and 50 mph across most of New England.
Cooler temperatures move in Thursday as high pressure builds back in with sunshine and highs in the low 50s. Friday into Saturday a system brings a chance for light snow, flipping to rain as temperatures warm.
Friday's highs before the front moves through will cool to the upper 40s, then will be in the upper 50s Saturday with late day clearing.
Sunday night into Monday another system brings in rain and scattered showers stick in the daily forecast through at least Thursday next week as the forecast becomes more uncertain but more unsettled. Highs range in the low 60s to 70s inland Monday, to mid-50s by Wednesday and Thursday.
