Berkshire County Forecast-Tuesday, September 24

Summary: There is not much change to the weather scenario or forecast since yesterday’s discussion. Our weather will be primarily influenced by a ridge of high pressure (full atmosphere) building over the region and its attendant surface high pressure system through at least the weekend. This will gives us dry, generally fair weather and seasonable temperatures for the foreseeable future. As stated yesterday, low level moisture rotating around a cut-off low pressure system over the Canadian Maritime will result in a buildup of clouds during the day Wednesday through Friday, mostly during the afternoon as the atmosphere destabilizes a bit. Aside from some patchy early morning fog, skies should be mostly sunny during the morning with a mixture of clouds and sun during the afternoons. We should see a return to mostly sunny skies over the weekend with high temperatures near 70 (lets hope!!).

Tuesday Night

Mostly clear and seasonably cold. Patchy fog developing toward morning.

There is no significant risk of frost tonight. Low temperatures generally near 40, with some upper 30s over the elevated terrain and in wind sheltered valleys.

Northwesterly winds at 5-10 mph this evening, becoming light after midnight.

Wednesday

After any fog burns off it  will be mostly sunny early, with some build up of low clouds as the day progresses, primarily during the afternoon. There will be a mixture of clouds and sun during the afternoon.

High temperatures in the mid to upper 60s in Pittsfield, North Adams, Adams and Williamstown; upper 60s in Great Barrington and Sheffield and; low to mid 60s over the elevated terrain and hilltowns, depending on elevation.
