A part of the latest AFD out of Tallahassee on the GOM mess.... this probably will prove to be much needed rain for the panhandle... LATEST SURFACE ANALYSIS SHOWS A WEAK SURFACE TROUGH JUST SOUTH OF THE CWA EXTENDING FROM EAST TO WEST ACROSS THE NORTHERN PORTION OF THE GULF OF MEXICO. THE SUBTROPICAL RIDGE EXTENDS EAST TO WEST ACROSS THE SOUTHERN PORTION OF THE GULF. TONIGHT THROUGH FRIDAY...EXPECT THESE TWO SYNOPTIC FEATURES TO SLIDE NORTHWARD OVER AND TOWARD THE CWA. A WEAK LOW-LEVEL CIRCULATION CENTER EMBEDDED WITHIN THE TROUGH JUST WEST-NORTHWEST OF TAMPA WILL CONTINUE TO TRACK NORTHEASTWARD TOWARD THE BIG BEND TONIGHT AND TOMORROW. WILL SHOW LIKELY POPS OVER THE EASTERN PORTION OF THE CWA DURING THE OVERNIGHT HOURS TONIGHT AND INTO TOMORROW MORNING. TOMORROW AND TOMORROW NIGHT...MODELS ARE BEGINNING TO COME INTO BETTER AGREEMENT WITH ANOTHER DEVELOPING WEAK LOW-LEVEL CIRCULATION SOUTH OF MOBILE AND TRACKING IT NORTHWARD TOWARD PANAMA CITY. THEREFORE...WILL LEAVE POPS IN THE LIKELY CATEGORY THROUGH THIS TIME PERIOD. FOR SATURDAY...EXPECT MAINLY SOUTHERLY FLOW ACROSS THE CWA AND PLENTY OF LOW/MID LEVEL MOISTURE WHICH WILL KEEP POPS NEAR CLIMO. ...Part of the TAE AFD @ 9:15pm...
