Biggest snowfall of this season on it's way...lots of ice to our south and east...could be bad!


Biggest snowfall for the season on the way. It’s a Nor’easter that wants to track into New Hampshire while injecting some warmer air aloft and causing some sleet to mix in, and even an ice storm across portions of southern and far eastern Vermont and New Hampshire. Those areas will not see the kind of snow that should fall from 10 to 18” starting Thursday night and lasting into the most of the day before pulling away late Friday.

There no doubt about these storms having been the worst to forecast since I’ve been doing this in the 80s. The Computer weather modeling of the tracks have “shifty” causing the trends to keep pulling westward instead of staying on or a little off the coast. These storm become more of a hybrid and the closer they are to the region, the more the chance for precipitation other than just fine dendrites and stellar’s .

See storm track but also the blue area showing modeled precipitation. Freezing rain may get as far north as the far Northeastern Kingdom of VT, but I’m expecting it as far west as Mad River Glen.

As the storm departs, the weekend should be an outstanding one for enjoying about a foot of new powder with bright sunshine courtesy of higher pressure.

On Sunday, this high pressure system will bring us warmer air aloft as it exits to the east. The next system might again fall in the form of rain for a time, before changing back to all snow Monday night and Tuesday morning. High pressure builds across the region Tuesday night followed by another impulse with a brief shot of 2 to 5” of more snow for Wednesday. Colder air behind that system should be god for snow making conditions and also preserve the snow.

Bottom line around a foot of new powder with excellent conditions to play in the snow for the weekend.
