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.

One front moving in is causing some rough weather in the Southeast today. Look for more big storms as another cool front moves in early next week, leading more unusual cool south.
High heat has a foothold west of the Mississippi but will struggle to surge east. Eventually, the heat will get beaten down even in much of Texas.
We're returning to more typical summertime weather with Texas hot and the Southeast steamy with spotty thunderstorms. The tropics remain quiet except for Wali's remains affecting Hawaii.
As the wet weather shifts east, the heat will build back west of the Mississippi again ... not that it won't warm back up in the Southeast, too. The tropics remain quiet except out by Hawaii.
The unusually nice weather in the Southeast won't last long. Meanwhile downpours will lead to flooding problems farther west the next few days.
It will get hot and steamy this weekend but we still expect to see cooler air arrive next week. The front leading the cooler air south will bring some areas active weather for several days.
