Snow is expected to stop in Worcester and the western part of the state before 9 a.m., gradually moving out of eastern Massachusetts by noon. Essex, Suffolk and Middlesex counties in the northeast part of the state may see snow showers through 5 p.m. on Sunday.

The snow will arrive Saturday between 10 p.m. and midnight. Once it arrives, it will hit the ground running. The majority of the snow accumulation will occur between midnight and 7 a.m. on Sunday. There will be some light snow and flurries between 7 a.m. and noon but very little additional accumulation.

Meteorologists are forecasting a series of snow storms, including 2 to 3 inches of snow in the Boston-area on Thursday before a chance for more than 6 inches this weekend.
