The Northeast is preparting for their biggest dump of the season so far. The big snow pushing into the Pacific NW is nothing new this season.
The storm is just starting to get going over the Northeast and will really start to crank up tonight as a low strengthens off the coast of New England. There is some warm air coming up ahead of the low moving across Northern New York so there will be a mix of rain in Southern VT, NH, and ME before it changes back to snow overnight. Northern NY across to Northern Maine we should see a general 6-12 inches of snow by Saturday.
Below is the snowfall forecast through Saturday. With the wrap around upslope snow showers continuing through the day on Saturday in Northern VT I would not be surprised to see over 18 inches on top of Jay and Stowe by Saturday night. Stowe could actually hit 2 feet if the upslope snow goes long enough Saturday. You can see the purple dot over that area. Less amounts of 4-8 inches will fall in the Southern half of the states due to the rain mixing in to start. I would still expect higher amounts on top of the mountains even down to Mt. Snow.
Here is a look at the snowfall forecast from the NAM forecast model off of wintercast.tripod.com. The legend is kind of small but green is 4-6 inches, grey 6-8, dark blue 8-10, light blue 10-12, pink 12-15, and red 15-18 inches. This will be the biggest snow to fall on Northern VT and NH so far this season.
Behind the storm plenty of cold air with a chance for more snow Tuesday and again Thursday of next week.
The Pacific NW will be getting dumped on simultaneously as another storm moves into the Pacific NW. The snow levels have bumped up to around 4000 ft. in the Washington Cascades but they will fall tonight with mainly a snow even for Mt. Baker South down to Mt. Bachelor in Oregon. The snow will fall through the day on Saturday before tapering off by Sunday.
Total snowfall from this storm should be 1-2 feet down the Cascades above 3000 ft. from Mt. Baker to Mt. Bachelor. Mt. Baker should pick up the heaviest amounts of snow with 2-3 feet possible up top by Sunday and Mt. Hood above 6000 ft. should pick up similar amounts. Mt. Baker already has a 15-19 foot base!
Here is the snowfall forecast from TWC. Once again off the chart for the Pacific NW and missing the boat over Mt. Hood and Mt. Bachelor.
There will be plenty more snow next week for the Pacific NW as more storms arrive by Tuesday. The snow on Saturday will progress East into the Northern Rockies where Jackson is expected to pick up 5-10 inches by Sunday. BA
