Summary: A storm system (surface low pressure system) tracking through the upper Great Plains and Great Lakes will drag first its warm front and then its cold front (following close behind) across our region tomorrow. This will result in a brief period of mixed precipitation, turning rapidly to freezing rain and then rain tomorrow morning, continuing as all rain into the afternoon. Temperatures behind the cold front are still relatively mild so we will not have a return to the very cold temperatures we have been experiencing in recent weeks and will have near normal to above normal temperatures for the rest of the work week. We will be between weather systems for a few days (Tuesday and Wednesday) without any storms or strong high pressure systems. However, scattered lake-effect snow showers are a good bet Monday night into Tuesday as strong west-northwesterly breezes blow across the lakes after the cold front passes. A weak low pressure system will scoot by to our south Wednesday night and Thursday. Right now it looks like it will miss us. A strong cold front will likely come through Friday and Friday night and put us back in the deep freeze next weekend.

Sunday Night

Clear in the evening with increasing clouds after midnight, becoming overcast by morning.

Temperatures will fall into the low to mid 20s in most locations this evening and then begin to rise after midnight as the clouds move in. Temperatures will likely reach the mid to upper 20s in most locations by morning. Temperatures could hit 30 in some parts of South County.

Light south-southeast winds increasing to 5-10 mph by morning.

Monday

Precipitation will likely begin between 7 and 9 am as a brief period of mixed precipitation that turns rapidly to freezing rain. Temperatures will be close to freezing and will rise above freezing in most locations within an hour or two after the rain begins, turning the precipitation to just plain rain by mid to late morning. The freezing rain could linger a little longer in some locations within the elevated terrain and hilltowns. However, temperatures should be above freezing everywhere by noon. Ice accumulations of 0.10″ at most will likely not cause any real problems as most roads have been treated during our recent snowfall. Rain will continue into the afternoon and should end by mid to late afternoon. Probability of precipitation near 100%. Rainfall totals around 0.25″.

High temperatures in the upper 30s in Pittsfield, Adams, North Adams and Williamstown, near 40 in Great Barrington and Sheffield, and mid to upper 30s over the elevated terrain and hilltowns.

South-southeast winds shifting to southerly and then southwesterly over the course of the day, increasing from 5-10 mph in the morning to 10-15 mph during the late morning to early afternoon, then decreasing to 5-10 mph late.

Monday Night

Mostly cloudy with scattered snow showers likely. Snow showers are most likely in central and northern Berkshire, particularly in the elevated terrain. Probability of precipitation 60% in these locations. There may be a dusting of snow in some locations. There is just a chance of snow showers in South County, with the probability of precipitation 40%.

Low temperatures in the upper 20s in most locations, mid 20s over the elevated terrain and hilltowns.

West-southwest winds at 5-10 mph in the evening, shifting to westerly and increasing to 10-20 mph after midnight.

Tuesday

Mostly cloudy and quite breezy, although it may be only partly cloudy at times, mostly in South County. There is still the chance of a snow shower, predominantly in the morning over central and northern Berkshire. Probability of precipitation is 30%. No accumulation more than a light dusting is expected.

High temperatures in the low to mid 30s in Pittsfield, Adams, North Adams and Williamstown, mid to upper 30s in Great Barrington and Sheffield, and upper 20s to low 30s over the elevated terrain and hilltowns (depending on elevation).

West-northwesterly winds at 15-20 mph with some gusts over 30, particularly in the elevated terrain.
