Mass. Forecast: Snowstorm Likely This Weekend

A winter storm warning is in effect for much of the region, with a coastal flood advisory along parts of the coastline for minor flooding.

The storm will track up the coastline Saturday night and early Sunday morning. While there could be some light snow Saturday afternoon, the bulk of the storm should arrive Saturday night and exit the region Sunday morning. The heaviest part of the storm will be from 11 p.m. Saturday until 7 a.m. Sunday.

A large swath of Massachusetts could see at least 8 inches of snow, with smaller snowfall accumulation in the southeastern part of the state.

Along the coastline, it appears enough warm air will move into this system to change the snow to rain. Over Cape Cod and the Islands several inches of snow will fall before the change to rain.

Friday night to Saturday: A few flurries, otherwise a mix of clouds and moonlight. Lows near 0 in the north, 12 in Boston and upper teens on Cape Cod.

Saturday: Clouds thicken. Some coastal flurries or very light snow. Cold — highs in the 20s. Steadier snow begins to spread south to north after 3 p.m.

Saturday Night: Snow, becoming heavy late at night. Snow mixes and changes to rain over Nantucket and Martha's Vineyard late. Rain/snow line moves northward overnight.

Lows in the 20s to mid-30s at the coast, teens inland and north.

Sunday: Storm ends early in the morning. Breaks of sunshine for the afternoon. Highs in the 20s inland and 30s over Cape Cod, but falling to the 20s later in the day.

Monday: Cold and dry.
