50/50 weather weekend for the Western Carolinas...

Good Saturday to everyone across the Foothills and Western Piedmont…

 

Quite a bit to go over here in the short term of the forecast and we’ll do that in this discussion. Later on today we will dig into the extended portion of the forecast and the all-important Thanksgiving Holiday.

 

A frontal boundary is steadily marching into the Tennessee Valley as of this morning and will charge eastward across the Appalachians and east of our area by early Sunday morning, This front will be a shot of cold air to the region and it looks to hit-and-hold rather than a quick retreat. The daytime hours of Saturday should not be top bad overall, we will see a gradual increase of clouds and an increase in southwest winds ahead of the front. High’s will top out close to the 60 degree mark.

 

A line of showers and even a few thunderstorms will accompany this front. Our western counties could see a few showers ahead of the main line, those may begin as early as sunset… regardless, conditions will deteriorate as we go through the evening as the front makes its approach. Showers will become more widespread and the wind will increase. Right now frontal passage looks to fall in the range of 10-11 pm in our Western Counties and between 1-2 am east of US 321.

 

Behind the front, winds shift around to the northwest and cold air gradually floods in dropping temperatures down into the 30’s and 40’s by Sunday sunrise. One thing of concern is that post-frontal winds have the potential of getting quite strong in the overnight/early morning hours of Sunday. Winds at about 5000 ft  could be in the 60-70 mph range so the high country looks to have a good chance of a high wind event. Here in our local area those favored sections of the Foothills could see wind gusts exceed 40 mph at times early Sunday and that could bring down a few trees outside the Blue Ridge gusts to 30+ may occur.

Those northwest winds will help create enough downslope to where Sunday afternoon temperatures may get up close to 50 degrees. That will serve as just a brief interruption in the cold air advection. Once the sun sets on Sunday evening temperatures will begin to drop off in a big way with low’s first thing Monday morning getting at or below freezing for most locations in our coverage. In the High Country temperatures will be much colder (teens and lower 20’s) which for ski country is great news for snow-making going into the Thanksgiving Week.

The very high peaks may even get some assistance from mother nature as the northwest flow could wring out scattered snow showers. That would be most likely occur early on Sunday.

With cold air firmly in place the start to Thanksgiving week will be on the chilly side. After the frigid start Monday morning temperatures by afternoon will only reach the lower 50’s area-wide under partly cloudy skies.

 

Have a great day...
