Sunday snow?

As I write, ACA is not under even a winter weather advisory, though I expect that to change either tonight or early Sunday.  NE of Asheville, from the Black Mountains north into VA, there is already a Winter Storm Warning for 3-5".  The GFS has us at only 1", with the much larger snow north. the NAM as us 1-3" by the time all is said and done.

Temps only slowly drop all night, in the upper 30s by Sunday morning...and temps then slowly drop through the day.  Precip will cross over to a wintry mix, ultimately over to all snow in the afternoon, with temps closing in on freezing by late afternoon.  In that scenario, even though we start 'warm' here in ACA, snow could fall hard enough to accumulate regardless, and make for potentially poor travel conditions by late afternoon.  Snow chances continue into the night hours, but really tail off after midnight.

 I'll look things over in the morning and update as necessary.
