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

Summary: The surface high pressure system that has been sitting on top of us for almost a week will continue to dominate the forecast into the coming week. The jet stream is way up in Canada, about where you’d expect it to be if this was August and not November.  That means the fair weather is going to continue.  However, the temperatures overnight will continue to be seasonably cold with conditions ideal for radiational cooling (clear and calm at the center of the high pressure system) and daytime highs will only be slightly above normal as the sun is so low on the horizon and the winds so weak that we will be unable to break the temperature inversion that develops during the overnights.

Monday night  

Tonight will be calm, cold and mostly clear, with only some thin high clouds.

Temperatures will drop to the low 20s (near the dewpoint) so expect to scrape more ice off your car again tomorrow.

Calm winds.

Tuesday

There will be increasing clouds due to a weak warm front moving through as we transition from the high pressure system presently over our region to a somewhat warmer high pressure system to our south and west. However, the clouds will be relatively thin and high to mid-level so the sun should be able to shine through them most of the day.

Expect another pleasant, seasonably cool day in the Berkshires. High temperatures will be near where they have been almost every day for the past week, slightly above normal, with highs in the mid to upper 40s for Pittsfield, upper 40s for Adams, North Adams and Williamstown and near 50 in South County. With the temperature inversion it will not be much cooler over the elevated terrain with high temperatures in the mid 40s.

Winds will be light and variable.

Tuesday night

There will continue to be considerable thin, mid and high cloud cover. However, there is no threat of precipitation.

The cloud cover will keep it just a tad warmer than the last few nights – with low temperatures in the mid 20s.

Calm winds.

Wednesday 

Most of the East coast will be under a broad ridge of high pressure going into Wednesday as the two surface high pressure systems merge and strengthen as the weak warm front and its associated mid and high clouds dissipate and it becomes mostly sunny.

High temperatures will be unchanged with highs in the mid to upper 40s in Pittsfield, upper 40s in Adams, North Adams and Williamstown, near 50 in South County and mid 40s over the elevated terrain and hilltowns.

Winds will be E-NE  at 5-10 MPH.

Looks like it will be a really nice day for people who are traveling on Wednesday to spend Thanksgiving with relatives.
