While the Northeast has already had a couple of big, snow-producing synoptic storms so far this season (one on October 27th, and another on October 29th), for Northern Vermont these events were fairly minor because the area was really on the fringe of the precipitation. A storm is developing now however, which is expected to bring more substantial accumulations to the northern part of the state. This storm is expected to head into the Ohio Valley later today, and then track east across Southern New England overnight. This storm may have some mixed precipitation with it, but the current forecasts do not indicated much mixing in the northern areas, and the chance is there for greater than 6 inches of snowfall. For a few more details, part of my morning report to the New England Regional Forum at American Weather is added below:
It was 17.6F and dropping when I left the house this morning around 6:00 AM, so this will certainly come in as the coldest morning of the season at our location thus far. I flipped on The Weather Channel before I left the house, and was surprised to see that the local forecast called for 6 to 10 inches at the Winter Weather Advisory level, but after reading the BTV forecast discussion, they spoke of the potential for mixing keeping totals down. The current point and click for our area down in the valley calls for 4 to 9 inches of snow, but doesn’t mention any mixing at this point.
Today: Sunny, with a high near 34. Calm wind.
Tonight: Snow, mainly after 1am. Low around 24. South wind at 6 mph becoming north. Chance of precipitation is 90%. New snow accumulation of 1 to 2 inches possible.
Wednesday: Snow, mainly before 4pm. High near 35. North wind between 3 and 8 mph. Chance of precipitation is 100%. New snow accumulation of 3 to 7 inches possible.
Wednesday Night: A chance of snow showers, mainly before 7pm. Partly cloudy, with a low around 20. North wind around 6 mph becoming calm. Chance of precipitation is 30%.
I didn’t really see much of a bump in the point forecasts for the local mountains, so we’ll have to see if that gets refined for the higher elevations. I’ve added the projected snow accumulations map from National Weather Service Office in Burlington below:

This evening, Matt Noyes posted his latest snowfall prediction map for this storm, and he’s pretty bullish on some of the totals in Northern New England, including parts of Northern Vermont. I’ve added his map below:
