Berkshire County Forecast – Friday, January 11

Summary: A warm front is lifting through the region this afternoon and evening with a few bands of rain showers. The last of these, and what appears to be the heaviest should move through early this evening. Temperatures are above freezing in most locations, however, temperatures are at or slightly below freezing over the higher terrain (e.g. Peru at 30 deg.) so watch out for some slick spots (mostly on walks and driveways) in those locations this evening. After the early evening band of rain there should only be a few lingering light showers or spotty drizzle for the rest of the overnight. Temperatures will rise above freezing in all locations by midnight as milder and more humid air moves in behind the front.

The warm front passage will open the door to an unseasonably mild weekend. Unfortunately, the subtropical airmass moving in behind the front also has a high moisture content. Therefore, low clouds will be quite stubborn and difficult for the low sun-angle to burn off both weekend days. Therefore, we should remain mostly cloudy with only some occasional breaks in the overcast. The best chance for sunshine is late on Saturday and during the late morning and early afternoon on Sunday. Despite the lack of sunshine, temperatures should still reach the 40s on Saturday and even the 50s in most locations on Sunday.

There is the slight chance of a few stray showers late on Sunday afternoon as the cold front at the leading edge of a cold trough in the jet stream advances eastward. This front should pass through with some showers Sunday night with a return to more seasonable temperatures but relatively dry weather early next week. It should still be relatively mild on Monday as we transition to the cooler polar airmass behind the front. A weak low developing along the front on Monday looks like it will pass out to sea well to our south. For you snow lovers and winter sports enthusiasts I don’t see anything to suggest any significant snowstorms for us, even in the long-range models. The snow cover will get wet this weekend and then, unfortunately, freeze solid next week…..

Friday Night

Overcast with  occasional rain showers this evening, mostly during the early evening. There may be a few isolated pockets of freezing rain over the elevated terrain. However, temperatures are over 30 degrees everywhere so there shouldn’t be much ice buildup. Watch for slick spots on walks and driveways in particular. Showers should taper off late this evening and there should only be a few scattered light showers and spotty drizzle after midnight. Probability of precipitation 100%. Rainfall totals generally around 0.10″.

Temperatures will rise a few degrees overnight to near 40 in Great Barrington and Sheffield, mid to upper 30s in Pittsfield, North Adams, Adams and Williamstown, and low to mid 30s over the elevated terrain and hilltowns.

Light southeasterly winds shifting to southerly after midnight.


It will average out mostly cloudy, with a stubborn low cloud cover, and unseasonably mild. It will likely be overcast in the morning with some more peeks of sun during the afternoon but it will be difficult for the sun, at such a low angle this time of year, to “burn off” (evaporate) these clouds.

High temperatures should be in the low 40s in Pittsfield, Adams, North Adams and Williamstown, low to mid 40s in Great Barrington and Sheffield, and near 40 over the elevated terrain and hilltowns. Should the sun make an unexpected, more prolonged appearance in the afternoon, add a few degrees to these highs.

Light southerly winds.

Saturday Night

Overcast and unseasonably mild. Fog may develop over the snowpack in some locations. There could be some spotty light drizzle.

Temperatures will not drop much with the low cloud cover and humid airmass. Expect temperatures to bottom out in the upper 30s to near 40 in most locations.

Light southerly winds.


Overcast early with some patchy fog and spotty drizzle. As the day progresses we should see a few breaks in the overcast. There is the slight chance of a shower during the late afternoon. Probability of precipitation 20%. It will be very mild for this time of year.

High temperatures in the lower 50s in Pittsfield, Adams, North Adams and Williamstown, low to mid 50s in Great Barrington and Sheffield, and near 50 over the elevated terrain and hilltowns.

Southerly winds increasing to 8-12 mph.
