Special Weather Statement issued December 14 at 5:26AM EST by NWS Boston/Norton MA
Dec 14, 5:26 AM Dec 14, 1:00 PM
Light snow has overspread the region very early this morning.
While the light snow will come to an end by lunchtime across
western Massachusetts and northern Connecticut...it will linger
into the afternoon further east especially across eastern
Massachusetts. Snow accumulations of 1 to 3 inches are expected
across much of the region with the higher amounts near and south
of the Massachusetts turnpike. Motorists traveling today should be
prepared for slippery travel and snow covered roadways.
