Model data continues to roll in and we are pouring over every single bit of it. The theme since last nights update is the idea of higher than projected snowfall totals. Many models now indicate that 2”-4” of snowfall will be possible for most all of Buncombe County. Surrounding counties also have the opportunity to see accumulating snowfall, and as you progress toward the NC/TN border, 6”-8”+ could be found. Below you can see our updated projected snowfall totals for this event on the map that Evan has produced. A widespread 2”-4” is possible in Buncombe Co. through Christmas Night. This will be a prolonged event, so even if you don’t see snowfall on the first round, there will be several chances through Christmas Day.
New Model Data
Below ill show several model solutions for you to observe. Each is a precipitation depiction forecast, and then the ensuing photo will be of the snowfall map associated with that model. This will give you an idea of where our forecast is based.

Flash Freeze Possible
As temperatures crash this evening right as the sun is setting, there will be a chance for a Flash Freeze around WNC. Roadways will not have enough time to dry up as temperatures plummet into the 20’s in only a short amount of time. Below you can see the sounding from the Nam 3km for Asheville at 8pm tonight. The temperature in the sounding at 5pm is around 50 degrees, so a 20+ degree temperature drop in 3 hours is likely. Fascinating stuff!!
Cold Hammer To Follow
The cold will really push into WNC on Christmas Day, and high will only be in the upper 20’s. Winds will be gusting over 20mph at times around Asheville, and it will be a bitter day to be outside. Wind chills will be close to negative on Saturday morning in the valleys and -10 degrees above 3500’. This is the coldest temperatures we have seen in a couple of years here in WNC. Bundle up, let those facets drip, & stay warm!!
