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.

Thanksgiving through the weekend look wet, cold and generally nasty for many places west of the Mississippi; a surge of tropical moisture from Sandra will likely lead to some flooding.
The convergence of multiple weather features over the southern Plains will result in a soaking rain; as cold air arrives parts of Texas and Oklahoma will see some ice and snow!
True arctic air coming into the South will give many places the chilliest stretch of the season so far. But, the weekend and early next week look mostly dry. Will that hold for Thanksgiving?
A storm coming out of the Four Corners will cause high winds, tornadoes and flooding rains through at least Tuesday, perhaps even later, as it marches across the eastern two-thirds of the nation. The long range is looking colder.
We'll be dealing with another intense storm early next week, this one having more of an impact on the weather down south. Severe storms and flooding rains both look to be threats.
Caveat emptor: It's November.
