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.

Here's my memories of Hugo, which hit South Carolina 25 years ago yesterday and today.
Brief weekend warmth in the Southeast will be replaced by cooler air again next week. Thanks to the fronts bringing the cool air south, Florida will stay wet.
Cool air nosing into the south will give some a nice and cool weekend, while others will be stuck under a front and get soaked. There are a few things to watch in the tropics but no imminent threats.
Some tropical features will affect the South in the coming days. I don't expect anything too serious except that moisture from them will lead to some soaking rains, especially where they interact with the front moving in.
A front will move into the South and stall, bringing rain and storms for many but those fortunate enough to be north of the front this weekend will have enjoyable weather.
Wind and rain will continue in eastern Virginia and Delmarva through tomorrow. Meanwhile, heat building again in Texas will be carried east ahead of the next cool front, which will cause some heavy thunderstorms.
