Sunny today; snow tonight

After a nice bit of fluffy snow for Christmas Day, we’re looking at a real storm coming into the area tonight.  Today will begin with sunshine, increasing high afternoon clouds, with highs 25-28, a bit warmer down south. Light, variable wind becoming East around 5 mph.

For Tonight and Beyond:

Tonight: Thickening clouds. Snow developing after midnight. Lows 19-22. E-NE wind increasing to 8-15 mph.
Thursday: Snow, may be heavy at times, and may briefly mix with sleet in the upper Connecticut River Valley. Highs 27-32. East-NE wind 10-20 mph.

The forecast discussion:A center of high pressure over central Quebec has ridges that nose into the northeast U.S. and wrap southwestward across the western Great Lakes then south through Texas.  The Quebec HIGH will bring settled weather to us today.  But a powerful, moisture-rich storm centered north of Nashville is pushing northeast and will bring snow to us starting late tonight and continuing into Thursday evening over southern Vermont, and into Friday morning over the northern half of the state.  The low will redevelop near the mouth of the Chesapeake Bay this evening and track to a little south of New York City by Thursday morning, then plow over the Cape Cod Canal to the vicinity of Cape Ann by Thursday evening, and to just west of Yarmouth NS by Friday morning.  There will be some shadowing immediately west of the White Mountains, and there may be a little mixing of the snow with sleet in far southern Vermont, but this will be a major storm: 8-16” should fall in general; locally greater along some high ridge lines, and perhaps 6-8” in the core of the shadow region along the far upper Connecticut Valley.
