The following forecast is provided by Joe Kravitz, the  instructor for the Introduction to Meteorology course, since there are no classes at BCC today due to Veteran’s Day:

Summary: A cold front will move through late tonight into the morning hours with a band of rain and showers that will end our spell of unseasonably mild weather. As colder air moves in behind the front, the precipitation may end as a brief burst of snow, snow “pellets” (graupel), or sleet during the mid to late morning, particularly over the higher terrain. However, accumulations will be limited as the ground is warm from our recent warm weather, surface air temperatures will be above freezing and any frozen precipitation will only fall for a brief period, although it may come down fairly hard for a time. Behind the front, a very large area of surface high pressure will build into the region. This will result in a prolonged period of fair and seasonably cool weather, with those stable weather conditions prevailing for the remainder of the week and possibly into next weekend.

Monday Night

Increasing clouds with rain and showers developing around 3 am. Probability of precipitation near 100%. Rainfall totals near 0.25 inches in most locations.

Temperatures remaining very mild, holding in the 50s, for most of the night, but dropping precipitously through the 40s after 4 am as the cold front moves through. Temperatures will be in the upper 30s in most locations by morning.

South-southwesterly winds at 10-15 mph, backing to west-northwesterly around 4 am with passage of the cold front.

Tuesday

Rain and rain showers early, possibly ending as a brief period of snow, snow pellets (graupel) or sleet in the mid to late morning, particularly over the higher terrain. All precipitation should end by noon or 1 pm at the latest. Probability of precipitation near 100%. Total melted liquid equivalent will generally be between 0.15 and 0.25 inches. Any snow/sleet accumulations will be mostly on grassy surfaces and mostly over elevated terrain and should measure one inch or less. Skies will begin to clear about an hour or two after precipitation ends and it will become mostly sunny by mid-afternoon.

Temperatures will continue to fall into the mid 30s in lower elevations and low 30s over elevated terrain through the morning hours. As precipitation ends and the sun comes out during the afternoon, temperatures will rise several degrees. High temperatures will be near 40 in Pittsfield, near 40 to the low 40s in Adams, North Adams and Williamstown, low 40s in South County and mid to upper 30s in the elevated terrain and hilltowns, depending on elevation.

Northwesterly winds at 10-15 mph in the morning, diminishing during the afternoon and becoming light by evening.

Tuesday Night

Clear and seasonably cold.

Low temperatures in the low 20s in most locations.

Light (less than 5 mph) northwesterly winds.

Wednesday

Mostly sunny and seasonably cool.

High temperatures in the low 40s in Pittsfield, low to mid 40s in Adams, North Adams and Williamstown, mid 40s in South County and upper 30s to near 40 over elevated terrain and the hilltowns, depending on elevation.

Light north-northwesterly winds.
