Ugh... I had to spend all my time forecasting for Yankee Territory today. It's a good thing things are relatively quiet in the South. Cold, but mostly quiet. How cold is it? Well, the afternoon temperatures in Virginia and the Carolinas are running mostly in the 40s and low 50s, more typical of December and January. Also, it did indeed snow for a while today in the mountains in West Virginia, and at lower elevation than I thought, down to 3500 feet. I suspect the higher peaks around there have a couple of inches on them.
In general, the chilly air mass is going to hang on for another day or so in the Southeast, but temperatures are going to moderate. Later this week, one front after another will move through, spaced out every couple of days. The air masses behind the fronts won't be as cool as the one we're dealing with now, but cool enough to knock temperatures back for a while. The farther east you are, the cooler it can get. But, the cool will only last a day before warmth surges northward ahead of the next front. So, temperatures will be on a roller coaster. The fronts won't have much moisture returning in front of them, so don't expect much rain.
Most of the area west of the Mississippi will miss out on the fronts, which will stall near the Arklatex. So, it will get progressively warmer and more humid back in Texas. Eventually, it will get summery again by the end of the week. The warmth and humidity will fuel some big-time thunderstorms when the next significant storm reaches the area over the weekend. The storm in question is an upper low west of California now. It looks as though it will cause storms later Friday or Friday night in West Texas, then into Oklahoma and North Texas on Saturday. Of course, the timing is uncertain this far out. But, the computer models are showing enough shear to be worried about a tornado outbreak. For now, I don't see another big shot of cold coming for a while, in fact, the end of the month looks pretty warm.

The storm we're dealing with now will pass by to the north, so the South won't see snow from it except in the Appalachians. Maybe it's a different story with the next storm coming late next week.
A storm coming out of the Southwest will pass north of us, meaning the South mostly sees rain. Rather cold air briefly hits behind it. An interesting situation is setting up for later next week.
Two separate storms will affect the South through Monday then there is a potential big storm to deal with right before Christmas.
The weather pattern is turning to a wetter and stormier one. Eventually, it will get colder, too, but not for another week or so.
The situation is complicated and there is uncertainty but it look as though some good rain and even some snow late this week and this weekend for much of the South.
A storm moving into Texas and Oklahoma tomorrow will cause thunderstorms and some may be severe. There is a slight concern for severe weather Tuesday in the lower Mississippi Valley, too.
