Barotropic Upper Low Situated Over The Mid Ms Valley Drifting Very
Slowly Ewd. An Occluded Front Will Stretch From A Weak Sfc Low Over The Md Ms Valley Through The Oh And Tn Valleys...Then Swd As A Cold Front Into The Wrn Gulf. Farther West An Upper Low Is Forecast To Retrograde From The Nrn Rockies Swwd Into Nev And Nrn Ca.

Fl Through A Portion Of The Sern States...

Greatest Potential For Thunderstorms Will Likely Exist Across The Fl

Unstable As Diabatic Warming Commences...And A Few Thunderstorms May Redevelop In Association With Seabreeze Circulations.
