This is a historic storm for Mississippi and points westward. TWC just said that the Dallas/Ft Worth NWS issued a wind chill warning for the first time ever. And the entire state of Texas is under a winter storm warning. That also has never happened before.
Here, in north central Alabama, the cold air has pretty much stayed to our west. It's cold, but nothing highly unusual. The high today was 31, 15-20 degrees warmer than Memphis. We have a winter storm warning too, but I'm thinking we in Huntsville/Madison will stay just to the east of most of it and nothing terribly unusual will happen here.
We'll see how it looks tomorrow morning.
