Snow for Vermont, Wind for Connecticut

What a nor’easter! Though the impacts here in Connecticut won’t be terribly impressive, from a meteorological perspective this storm will be a monster. Given the projected strength of this thing it’s possible that enough strong upward vertical motion may cool the atmosphere enough to produce heavy snow over the Green Mountains.

The question becomes just how much forcing will exist on the backside of this low. The 12z NAM (as usual) is the most extreme with strong lift as the low spins north of Boston. This results in a heavy, windswept, accumulating snow above 2000 feet north of the Mass Pike with near blizzard conditions at mountain summits in Vermont (and probably even Mt. Greylock, MA). The 12z GFS probably has enough lift to produce a couple inches in Vermont (but not the foot or so the NAM is printing out).

It’s possible a few snowflakes will fall Friday afternoon across Litchfield County if this storm is indeed strong enough but no accumulation is expected.

What seems likely is that 1″-3″ of rain will fall across the state with gusty westerly and northwesterly winds as the storm passes. The winds could be strong enough to down some trees and powerlines depending on exactly how strong the storm is and where it winds up stalling.

My friends up at Mt. Snow and Killington should get ready to hike with their skis and boots since they may be able to get some early season turns in above 2000 feet.
