A large area of low pressure is currently moving through the center of the country, bringing with it a large area of heavy rain and severe weather. It is making its way towards the Carolinas, and it will be affecting your weather soon.
Tornado watches were issued before midday Saturday across portions of the deep south, and this system is making its way towards the Carolinas. Some good news is by the time the storm makes it to the Carolinas Saturday night and Sunday morning, it will be in the process of weakening; however, we can not rule out severe weather, including an isolated tornado, in the Carolinas.
The greatest impact this storm will have on us will be the heavy rain. A narrow band of heavy rain will set up across the Carolinas Sunday night through Monday. The greatest question is where will this band set up. It will only be around fifty miles wide; however, it will result in 3-4 inches of rain where it sets up.
Right now, models show the area setting up just east of the mountains in the foothills and western piedmont of North and South Carolina. Charlotte, Greenville-Spartanburg, Hickory, Winston-Salem, and Greensboro would be affected if this solution was to verify. This can always change, so we will need to continue to watch and see where the rainband sets up.
After the storm moves off the coast Tuesday morning, we see a big push of cold air. Snowflakes are possible in the mountains; however, accumulations will be light.
For the rest of us, it will be cold for Christmas Eve and Day. Temperatures will be five degrees below average.
