12z GFS is interesting at the 500mb level with the trough going negative tilt with the second wave at hour 144 (12z Sun, Jan. 3rd) at the Bama/Georgia border. This pops a strong coastal low that heads up the Carolinas and then out to sea. Mountains get a few inches as most the precip shield stays to the southeast which is fine for now. At least there is a signal at the 500mb level. I’m interested in the 12z Euro now that it showed this wave last night.
