...Gulf Coast states...
Low-amplitude southern-stream shortwave trough currently located
over southeast TX will move through the lower MS Valley and
Southeast States tonight. 00Z RAOB data near and inland from the
Gulf Coast show weak surface-based instability (200-500 J/kg MLCAPE)
in a corridor east of a slow-moving cold front that extends from
northern AL into southwest LA. A modest southwesterly low-level jet
will evolve within the marginally unstable warm sector, and forcing
for ascent will remain sufficient for thunderstorms, though coverage
should gradually decrease as the surface layer stabilizes.
Are we talking next Saturday for the Tennessee Valley? I have plans to go on a day trip to outside Chattanooga with some friends.Looks like the next two weekends have a low traveling in just the right spot to put most of Dixie in line for some rough weather. I’m a newbie at reading maps so maybe someone with more knowledge can verify. Still 7 and over 14 days out so lots of time to speed up slow down or disappear completely.
