12/09/17 Noon Winter Weather Update: Snow coming to an end, next blast of cold to move in tonight.

Good Saturday afternoon, the first winter storm of the season is winding down and weather will begin to improve this afternoon…however the threat of re-freeze will emerge as we have a reinforcing shot of arctic air set to invade the Western Carolinas tonight.

 

As of the noon hour one final band of snowfall is moving through the Foothills and Western Piedmont. This will being a brief uptick in the snow activity from west to east but it will be on the move and out of the region by mid afternoon. Behind that we may even see hints of a break in the cloud cover.

The powerful jet that helped spawn out winter storm is located off the Mid-Atlantic Coastline this afternoon and is moving up the coastline, meanwhile northwest flow is about to take over driving another piece of energy into the Appalachians. The upper low centered over Illinois will cross to our north tonight and early tomorrow but it won’t spare the region from getting a blast of cold air straight from the northern latitudes.

Once this low passes by tonight expect winds to start turning out of the northwest and for our friends in the high country, they may get additional snow from northwest flow. Here locally, a couple flurries might break containment into parts of Burke, Caldwell and McDowell Counties but no additional snow fall of significance is expected.

 

The big story here locally will be the cold air advecting in on a freshly laid down snowpack. The end result is going to be a very cold night with temperatures likely to plummet down into the upper teens in the foothills, with 20’s everywhere else. This cold air is going to result in a re-freeze of current snow and water on the ground which could lead travel issues beginning tonight and lasting through Sunday morning. The most prone areas will be on secondary roads, driveways, etc. Keep this in mind as you head out to Sunday morning services. With the cold weather coming it would also be encouraged to get that snow off the automobiles since temperatures are still at or above freezing.

Sunday looks to be quite chilly with high’s likely staying in the 30’s in the foothills and a few low 40’s in the Piedmont.
