BOSTON — A nor’easter brought wind-whipped, wet snow to Massachusetts on Thursday, and coastal flooding is expected in communities still recovering from February’s blizzard.

The National Weather Service upgraded two-day snowfall total forecasts with a winter storm warning through midday today for several areas of the state as temperatures that stayed above freezing Thursday fell overnight. Up to 12 inches is forecast in central Massachusetts and Boston’s western suburbs, up to 10 in Boston and areas south and northeast, and up to 8 inches in western Massachusetts.

A coastal flood warning is in effect through this evening for east-facing shores, with a 3-foot high tide expected in some areas at the peak this morning.

Vulnerable areas include Salisbury and Newbury north of Boston, including Plum Island, and areas south of Boston from Hull, Scituate and Plymouth to Sandwich on Cape Cod.
