Low Pressure continues to dump snow across interior New England this evening, with up to a foot possible along the mountains of interior Oxford/Franklin/Somerset/Piscataquis cntys. Rain and sleet will mix in at times across the valleys, with rain along the coast. Winds will also be gusting quite high along the immediate coast as low pressure moves inland. Bottomline... expecting a nasty night across western Maine with snow...heavy at times... and very blustery conditions lasting into the day on Wednesday.

Lake Effect Potential...
Off Lake Ontario... as winds continue to back from the west, and eventually southwest, lake effect plumes should develop east/northeast of Lake Ontario overnight lasting into the morning. A general 2-6" is expected before the snow diminishes. However... expecting to see redevelopment by Wednesday evening, with significant snows possible. Greatest impacted area appears to be the Tug Hill region of northern Oswego/central Lewis into southern Jefferson cnty. Potential exists for up to a foot by early Thursday morning, with snow continuing into the better part of Thanksgiving Day. When all is said and done, totals will likely exceed a foot across the Tug Hill region. Have expanded accumulations into the northern Adirondacks cntys of Herkimer/Hamilton where locally 6-12 possible... with lighter advisory amounts to the east. Will re-assess this potential with next update.

Western PA update...
Lake effect and upslope snows continue in the Laurel Highlands as a result of the backlash effects of the storm that continues to affect the Northeast. Winter weather advisories in the Laurel Highland counties of Cambria, Somerset, and Fayette counties have been upgraded to winter storm warnings. The highest total amounts for this event are to occur to the west of US 219, where 8-12 inches with isolated higher amounts are possible in the ridges. Additional snowfall is possible thru Wednesday into Thursday morning in these areas as well, so more updates to come.
