Also the 12z UKMET looks half decent to my eyes. Doesn't go out far enough to see what happens. However, closed off 500mb low, over central MS/AL, neutral (going neg soon maybe) on the last panels on pivotal. Some CAD in place but not super cold in the mid-atlantic. One thing I'm trying to learn about. How does one predict what will happen to the cold air in place based on 500mb charts?
