The south of Vermont is still digging out after more snow came Monday, but things should be relatively quiet this week, apart from scattered snow showers. Glare ice was reported across the northern parts of the state last night, with accidents on Interstate 89 near Montpelier, and warnings from police about dangerous driving conditions in . This morning Route 78 up in Alburg is closed due to a tractor trailer accident, and likely to be shut for a few hours more.

If you scroll down to the forecast description, you’ll see the inherent uncertainty in weather forecasting – this weekend the possibilities range from ‘light snow’ to ‘a blockbuster snowstorm.’ That’s quite a range…

In the northeast, snow showers are likely over hilly terrain, with scattered snow showers on valley floors. Possible accumulation of a trace to 2 inches, with highs 32-37. W-SW wind 10-15 mph becoming WNW at the same speed.
In the south, mostly cloudy mountains, partly cloudy valley floors. Good chance for a passing snow shower mountains, accumulation of a trace to 2 inches possible. Just scattered snow or rain showers on valley floors, mainly west of the Green Mountains. Highs 37-42. SW wind 10-15 mph gradually shifting to W-WNW during the PM.

Tonight: Scattered evening flurries, otherwise gradual clearing. Lows near 20.  West wind 10 mph or less.
Wednesday:  Mostly sunny. Highs 35-40.  Northwest wind 5-15 mph

Extended Forecast:
Wednesday Nt: Becoming mostly cloudy. Slight chance for light snow along the Massachusetts border. Lows 20-25.
Thursday: Becoming mostly sunny. Highs 37-41.
Thursday Nt: Increasing clouds. Slight chance for snow showers. Lows 20-25.
Friday: Mostly cloudy. Slight chance for snow or rain showers. Highs 35-40.
Friday Nt:  Variable clouds, slight chance for snow showers.  Lows 13-18.
Saturday: Partly cloudy. Highs 30-35.

Forecast Discussion:
A mid-level cyclone passing just to our north, good low-mid level moisture, and a westerly flow off the Great Lakes are promoting snow showers over northern Vermont today. In southern Vermont only scattered snow showers are being noted, limited primarily to the Green and Taconic Mountains. As is usual in these kinds of situations, snow amounts are highly tuned to the topography, with the greatest amounts over high terrain, and lesser amounts on valley floors.  Colder air will follow the passage of the mid-level cyclone tonight, but temperatures the next few days will run at or slightly above normal, with no true arctic air tapped.  The weather will be fairly quiet from later this evening through Thursday.  Heading into the weekend, a deep trough will be carved out over the eastern US, and somewhere within that trough significant low pressure will form.  But it’s still way too early to know just where that will take place.  Possible results at this point range all the way from scattered snow showers or a period of very light snow, to a blockbuster snow storm.
