Berkshire County Forecast – Friday, January 27

Posted at 3:15 pm


Berkshire County will see a return to more typical winter weather for the foreseeable future. Temperatures will hover within several degrees of average, with some slight ups and downs over the next week or so. West-northwesterly breezes will bring mostly cloudy skies with a few, scattered lake-effect snow flurries for the next few days. On Monday we will likely see a bit more sun but it will be colder. An Alberta Clipper type low will slide by to our north and likely give us a little light snow Tuesday and/or Tuesday night, but will probably only drop a few inches at most. The next chance for a significant storm doesn’t look to be until late next weekend into early the following week.


A deep and broad trough in the polar front/jet stream wave pattern is covering most of the U.S. this afternoon. A deep and broad area of surface low pressure in the Canadian Maritime, along the northeastern margin of this trough is creating a steep pressure gradient that is generating strong west-northwesterly breezes across the Northeast. This wind is generating bands of lake-effect snow showers downwind of Lake Erie and Ontario. A few, but not many of these showers are making it into Berkshire County as a few flurries. The trough will propagate very slowly eastward and the surface low will track very slowly northeastward so our weather will not change much over the weekend. Expect mostly cloudy skies with a few scattered flurries with seasonable temperatures. We may see a little bit more sun on Sunday, but don’t count on it.

The trough will eventually amplify and narrow, becoming centered over the Northeast on Monday. This will make for a bit colder day on Monday but with more sunshine as surface high pressure briefly noses in from the south. A disturbance/short-wave will develop along the back edge of the trough and generate a weak, Alberta Clipper type low over south-central Canada on Monday. This low will track southeastward across the Great Lakes on Monday night and then slide by just to our north on Tuesday and Tuesday night. This low will likely generate a dusting to a few inches of snow in Berkshire County but I will update accumulation predictions in my next post on Monday afternoon.
