I'll be looking for Killington, Sugarbush, and Mad River Glen to verify these higher amounts. The time frame is from tomorrow evening till Wednesday morning. I expect snow to overspread the region tomorrow evening between 7pm and 10pm with snow becoming heavy at times during the overnight hours. Snowfall rates of 1-2" per hour are possible for an extended period in the central Green Mountains with occasional 1"+ rates from I-89 northward. Needless to say, all of this snow will likely fall while the lifts are closed so Wednesday morning should be pretty sweet.

Warm air advection will be the main driver of the snowfall as warmer air between H8 and H7 overrides this arctic airmass currently in place. I'm seeing favorable snow growth for this system so will follow ratios of 12-14:1. Arctic air in the boundary layer should allow for immediate accumulation on all surfaces, too. Good upper level divergence and H7 frontogenesis is maximized across central Vermont back towards the southern Adirondacks. The 4km BTV WFR model is indicating two meso-scale bands possible...one across central Vermont and the other stretching from near Jay Peak to BTV to Oswego, NY. It'll be interesting to see if there is an enhanced area of snowfall removed to the north away from the heaviest precipitation across central/southern VT.

I'll have another update tonight but it this looks like a fun, quick hitting snowfall that'll add another layer of pow. Might want to make plans for Wednesday...
