Champlain Valley Weather Discussion:

OVERVIEW
         Two areas of energy are forecasted to merge together near the Delmarva peninsula to spawn a single low pressure system that will push Northeast. The exact track of the low pressure system continues to remain unknown. Eitherway measurable snow will be seen across much of Vermont, and portions of Northern New York.

SNOW
         Currently weather models continue to diverge on the exact track of this system. The hi-res models are in the west camp, and the GFS and a couple other global models are in the East camp. The exact track will determine how far measurable snow will make it into Vermont, but either track will bring measurable snow to southern Vermont. At this point I will split the track pretty much down the center but just a hair further to the west. This results in significant snowfall across much of Vermont. With lesser amounts across Northern New York.

         Snow should spread across much of the region by tomorrow morning. Snow will be going heavy across southern Vermont where snowfall rates as high as 4 inches per hour are possible. Across central Vermont some heavy snowfall rates of 1-2 inches per hour are possible, and across norther VT and extreme eastern NY snowfall rates of a half to 1 inch per hour are possible for a brief time. Depending upon the exact track more or less snow could occur for central and Northern Vermont.

SNOW
         Winds will occasionally be rather gusty with gusts up to near 35MPH at times, especially across Southern Vermont. But at this point it should not fall under true Blizzard criteria. Stay tuned for further updates on this developing weather situation.
