Once in a while lake effect snow from Lake Ontario can stretch all the way into Connecticut. That’s happening tonight. Up to an inch of accumulation is possible in the towns of Torrington, Harwinton, Goshen, Cornwall, and Sharon.
All of this is being aided by a weak vort max enhancing lift and allowing the lake effect snow streamer to become longer than what we normally see.
More weak disturbances will slide through New England Monday and other batches of snow may pop up. Minimal accumulation is expected but some areas could see a coating or half inch.
Behind the low pressure that brought rain, freezing rain, and sleet to most of northern New England a much colder air mass has moved in. It’s plenty cold (and dry enough) to fire up the snow guns tonight and Mother Nature may have some tricks up her sleeve tomorrow.
Here’s the 18z GFS forecast of 500mb heights and vorticity valid at 1 p.m. Saturday. You can see an impressive vort max sliding through Vermont and New Hampshire. This will provide “lift” in the atmosphere and when coupled with a strong westerly wind upsloping over the Green Mountains I expect 1″-3″ of snow at the higher elevations, particularly for Killington on north. Jay Peak and Stowe could pick up 3″-5″ near the summit. It’s possible places like Mount Snow and Stratton get a quick inch or two if the atmosphere is able the moisten up enough.
It’s been a disappointing start to the winter up north but this is better than nothing!
