Western Massachusetts and Northern New England have seen plenty of early-season snow, but Boston is still waiting for its first measurable accumulation. This could change by late Saturday as a weak but quick-moving coastal storm veers close enough to bring scattered to steady light snow overnight Saturday into early Sunday afternoon — potentially affecting fans planning to attend the Patriots-Bills game at Gillette Stadium.
Snowfall will be brief, but still impactful enough for winter weather advisories across most of Southeastern Massachusetts, the Cape, Rhode Island, and southern Connecticut. Roads will be slippery, especially Sunday morning.
Here are the latest forecast snowfall totals for the region. Some snow could start falling from 10 p.m. to midnight:
• Coating to 1 inch — Parts of the North Shore near the New Hampshire border, west along Route 2 to the Berkshires; coastal and southern New Hampshire and southern Vermont.
• 1 to 3 inches — Greater Boston west to the Berkshires, along and south of the Mass Pike, Southeastern Massachusetts, Outer Cape, inland Rhode Island, and Connecticut.
• 3 to 4 inches — South Coast of Mass., coastal Rhode Island, most of Cape Cod, and the islands.
These maps provide further storm details:
Boston typically averages its first 1-inch snowfall on Dec. 11, though this season has only seen trace amounts so far, despite the cold start to December. Temperatures, though, will be cold enough for snow this weekend, around freezing.
After the storm: Polar vortex cold moves in
Much colder Arctic air will follow on the heels of the storm, dropping Sunday night temperatures into the teens and keeping Monday in the 20s.
