Rain showers are expected to begin in the early afternoon, moving from west to east across the state. Most of Massachusetts, including Boston, Worcester and Western Massachusetts, can expect to see rain the rest of the day as temperatures are forecast to reach the low 40s. The Berkshires could experience a mix of rain and light snow.

A winter storm watch has been issued in Massachusetts ahead of a significant winter storm expected to make for a messy Sunday night before some of the coldest air of the season moves in.

We've got some accumulating snow to kick things off. That will be followed by the coldest airmass of the winter season thus far. Finally, in the longer range, it appears that an active/stormy pattern is going to unfold over the next few weeks across the eastern United States.
