A Winter Weather Advisory has been issued for much of central and western North Carolina for today and tomorrow. As usual, computer models are all over the place with regards to the amount and form of precipitation the region will receive from this developing winter system. There is the potential for a significant snow in western North Carolina and significant ice in the foothills and Triad. The foothills and Triad may also see accumulating snow in addition to ice and sleet. This is a very complex and difficult storm to predict, and residents should prepare for the possibility of some power outages in central and western North Carolina. The biggest uncertainty is where a band of heavy, wet snow will develop tomorrow and how large that band will be. It could develop in the foothills or the Triad along the deformation band, but there is virtually no way to know now where it will occur.

From Meteorologis WxSouth:

WxSouth
Overall, I'm sticking with my map from yesterday. This is playing out about like this. Snow in northwest NC turns to sleet. Several inches of snow from Asheville to Boone to southwest VA mountains but the max snow should be near Boone to the middle NC foothills where most moisture arrives when its cold enough aloft. The worst part will be in Greensboro and just west of the Triangle down to middle NC, Salisbury, Hickory, Statesville to Forest City Marion areas where temps will fall into upper 20's during the night and freezing rain and sleet is falling hard. The high pressure remains inland all the way up until 7 am Friday morning, then we lose that tap of dry cold dewpoint air, and that allows temps at the surface to finally go above freezing.
For southern and middle Virginia, it depends on when the moisture comes that far north, while the high is still in position. It looks like the best moisture is arriving in Lynchburg to Richmond just around 7 to 10 am, and by then, the time of day and the fact the high is pulling out means less ice and snow threat there, so you see a tight graident on how this evolves. For upper SC, the models may not be quite cold enough. I don't trust the surface temps just yet when it shows the 32 line stopping at the GSP area, but it could.Its always looked close there.
For northeast GA, same..the sub 32 degree air could come into that region tonight and lock in at the surface. Its very close, adn that could mean a big ice storm there as well. don't let your guard down. This will come down to watching radars and temps, observations tonight, not the models anymore.
Bottom line is this looks pretty bad for the middle and western part of NC because of perfect timing and evolution of the storm. I expect some power outages by dawn tomorrow somewhere in the tarheel state and possibly for southern tier of counties in VA as well, possibly even northeast GA and upper SC too..
Map issued yesterday.

We've got 2-3 inches of snow at the foot of Grandfather Mountain and it still laying it down. The official weather report is calling it "wintry mix." When it first started around 6:00 pm, it was snow and sleet mixed, but it's been all snow for the past 2-3 hours. It's covering everything including pavement.
