Champlain Valley Weather Discussion:

OVERVIEW
         Low pressure over the open waters of the Atlantic is pushing moisture down upon the region resulting in accumulating snow.

SNOW
         An update from Jericho, VT indicates 10.5 inches of snow has fallen. This tells me the Warning for the Western slopes is well needed, and an update on snow accumulations is needed as well. Above is an updated map, basically to indicate an area of 12-18 inches of snow along the Western slopes of the Green mountains primarily in Eastern Chittenden county where the snow has not stopped today. Moderate to heavy snow is ongoing at this time. Further west in the immediate Champlain Valley either no snow, or only flurries have been occurring today, with minimal accumulation. As the main forcing mechanism swings through the area later this evening, this should help squeeze out moisture into the Valley as well. Stay tuned for further updates on this developing storm.
