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 heat wave will go on in Oklahoma and parts of Texas for several more days but it will ease some in the Southeast next week. Florida, the Gulf Coast and Texas will see more typical summer heat and humidity. The East Pacific tropics remain very active but the Atlantic is still quiet for now. Maybe there will be signs of life in the Atlantic at the end of the month.
For most of the South, there will be no real break from the intense heat for the next week. A few areas, such as Florida, the Gulf Coast and South Texas will see more typical summer heat. Also, a front will affect a part of the Southeast with thunderstorms and slightly cooler air next week.
Intense heat will cover the South through this weekend. Some will see the heat ease early next week, but not many. The Atlantic tropics remain quiet, the East Pacific very busy.
The extreme heat now building over the middle of the nation will spread into more of the Southeast through this weekend. It looks as though the heat will ease early next week in some areas.
Extreme heat will be setting up for many areas east of the Mississippi this week with widespread triple digits. Meanwhile, many in the Southeast will see the heat ease this week, but it will stay some flavor of hot in the Deep South.
Intense heat will build anew in most areas west of the Mississippi the next few days while fronts pushing into the Southeast will ease the heat in some areas. Close to the East Coast, there will be some more noticeable cooling around the middle of next week.
