I’m reducing snowfall totals based on an analysis of all new data. It seems highly likely there will be a layer of warm air aloft that makes it to us overnight. So, while surface temperatures will be in the mid 20s, it will be above freezing at 10,000 feet. So...
Asheville: 4-8" of snow and 1-2" of sleet, no ice
Hendersonville: 3-7" of snow and 2-4" of sleet, some minor glazing possible
Now, if the warm nose fails to materialize (possible, but seems like it will), then the forecast is unchanged from yesterday:
AVL: 10-15"
HEND: 15-20"
So you see what a huge deal this layer of warm air is aloft. I will make another update/revision this evening.
