Summary: The only significant change in the forecast from yesterday involves the possible light snowfall event for Sunday. It looks like the surface low developing along the coast will be weaker and farther off the coast than it looked yesterday. I expect we will only get from a dusting to an inch at most Sunday and Sunday night.

Friday Night

Partly cloudy and cold.

Temperatures will fall as skies partially clear and winds diminish overnight. Low temperatures near 10 in most locations, mid to upper single digits over the elevated terrain. Wind chill temperatures near zero.

West-northwesterly winds at 10-20 mph in the evening, shifting to westerly and diminishing after midnight, becoming relatively light at 5-10 mph by morning.

Saturday

It will be mostly sunny to partly cloudy (more sun than clouds) in the morning, becoming overcast during the afternoon. There is the chance of a snow shower late, particularly over North County. Probability of precipitation 30%. No accumulation expected. Remaining cold.

High temperatures near 20 in Pittsfield, Adams, North Adams and Williamstown, low 20s in Great Barrington and Sheffield, and mid to upper teens over the elevated terrain and hilltowns.

Southwesterly winds at 5-10 mph in the morning, increasing to 10-15 mph in the afternoon.

Saturday Night

Overcast with the chance of a snow shower early, particularly over North County, then partial clearing overnight. Probability of precipitation 30% early. No accumulation expected.

Low temperatures in the low teens in most locations, near 10 over the elevated terrain.

Light southwest winds in the evening, become light southeasterly to calm after midnight.

Sunday

Becoming overcast by mid-morning. A little light snow will likely develop during the afternoon and continue through the evening. Probability of precipitation 60%. Accumulations should be a dusting to 1/2″ at most in most locations, although there could be as much as an inch in a few locations over the elevated terrain and hilltowns.

High temperatures in the low 20s in Pittsfield, low to mid 20s in Adams, North Adams and Williamstown, mid 20s in Great Barrington and Sheffield, and upper teens over the elevated terrain and hilltowns.

East-southeasterly winds at 5-10 mph.
