Morning Update: Previous forecast remains in tact overall. Most noticeable difference was to pull back on accums. across western/central/southeastern Pennsylvania. Precipitation associated with primary low has been very disorganized overnight here producing only very minor accums, so feel threat of seeing anything more than 2 or 3" has diminished.
As for the main show set to unfold later this afternoon thru Monday morning. Latest model guidance suggest the coastal will take shape and develop a bit further east than previous runs. With this in mind...have cut back on the sig snow accums across the western Catskills and relegated any chance to receiving wrng snow to far eastern portions of Delaware/Otsego cntys in NY.
In turn, this slight eastward shift will likely bring higher totals into the immediate Boston metro area. Therefore, have bumped totals up here a bit to 3-6". Have also brought heaviest axis of snowfall closer to the coast along downeast Maine. More on this area in a moment.
Last area of adjustment... have increased totals across the Tug Hill/northern Adirondacks due to expected lake enhancement/effect from Ontario...especially tonight as winds increase out of the west/northwest as low pressure bombs out along the New England coast.
Across central/northern New England... buckle up and make sure your tray tables are in their upright and locked positions. A classic Nor' Easter will be affecting our weather over the next 36 hours in the form of heavy snow/high winds/dangerous wind chills with blizzard conditions likely later this evening/overnight as the storm reaches the Gulf of Maine. Along the coast...the Low Pressure may track just close enough to bring the chance of sleet across the immediate coastline. This will limit accumulations somewhat...but on average still expecting 8-12". Across interior...10-20" is likely stretching from northern VT thru most of NH/ME...with highest totals in the northern mtns. of NH/interior ME. Localized accumulations could exceed this amount. Winds will only throw fuel on the fire as system really begins to crank up as it chugs off to the northeast into the Canadian Maritimes. Widespread blowing snow will continue well into Monday even after snow has ended. This will make travel extremely difficult if not impossible...especially on secondary roads. Power outages also expected...especially across Maine. Bottomline... any outdoor activity would be strongly discouraged. Best advice would be to stay inside, fetch a bowl of New England Clam Chowder, and keep warm by the fireplace!
