The following forecast is provided by Rebecca McLaren, in conjunction with the  instructor, as part of lab work for the Introduction to Meteorology course:

Summary: It will be unseasonably mild through Tuesday night as the jet stream has once again shifted well to our north. In fact, it will be even warmer on Tuesday than today as a weak warm front moves through the region with lots of clouds and a few scattered light showers or sprinkles late tonight into Tuesday morning. The jet stream pattern will become more amplified on Tuesday and the leading edge of a trough in the jet stream will move through as a cold front, bringing us a period of rain Tuesday night. It will be breezy and cooler behind the front on Wednesday. However, temperatures will only drop to near seasonal levels. Considerable sunshine and seasonable temperatures will return on Thursday and Friday as surface high pressure builds back into the region.

Monday Night

Partly cloudy this evening, becoming mostly cloudy after midnight. There is the chance of a light shower or a sprinkle toward daybreak. Probability of precipitation 30%. Rainfall totals should be less than 0.05”.

It will be unseasonably mild. With considerable cloud cover, and dew points in the upper 30s in most locations, temperatures should only fall into the upper 30s to near 40 by morning.

Light northwest winds shifting to light southerly after midnight as the warm front passes.

Tuesday

Mostly cloudy with a chance of scattered light showers or sprinkles in the morning. Probability of precipitation 30%. Any rainfall should total less than 0.05″. There should be some peeks of sun as it becomes partly sunny for a time during the afternoon.

It will unseasonably mild with high temperatures in mid 50s in Pittsfield, mid to upper 50s in Adams, North Adams and Williamstown, upper 50s in Great Barrington and Sheffield and low 50s in the elevated terrain and hilltowns.

Light southerly winds in the morning increasing to 8-15 mph in the afternoon.

Tuesday Night

Increasing clouds during the evening followed by a period of rain and rain showers beginning near midnight and ending by daybreak. Probability of precipitation 80%. Likely rainfall totals between 0.15″ and 0.25″.

Temperatures holding in the low to mid 50s until midnight and then falling to the mid 40s toward daybreak in Pittsfield, after passage of the cold front. Temperatures should fall to the upper 30s to low 40s over the elevated terrain and hilltowns but only the upper 40s in South County.

Southerly winds at 8-12 mph shifting to northwest after midnight, following frontal passage.

Wednesday

Partly cloudy in the morning, then becoming mostly cloudy during the afternoon. It will be breezy and much cooler than Tuesday.

Temperatures holding steady in the mid 40s during the morning in Pittsfield, Adams, North Adams and Williamstown, upper 40s in Great Barrington and Sheffield, and upper 30s to low 40s in the elevated terrain and hilltowns. However, temperatures should begin falling during the afternoon, reaching the mid 30s by nightfall in Pittsfield, Adams, North Adams and Williamstown, upper 30s in Great Barrington and Sheffield, and upper 20s to low 30s in the elevated terrain and hilltowns.
