   AREAS AFFECTED...SRN AL AND EXTREME SW GA AND A PORTION OF THE FL
   PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 071832Z - 071915Z
   
   CORRECTED FOR WORDING IN FIRST PARAGRAPH
   
   THREAT FOR ISOLATED STRONG WIND GUSTS AND HAIL WILL EXIST THIS
   AFTERNOON FROM SERN AL...SWRN GA AND POSSIBLY EVENTUALLY INTO THE FL
   PANHANDLE. WW IS NOT ANTICIPATED AT THIS TIME...BUT AREA WILL
   CONTINUE TO BE MONITORED.
   
   A SMALL QUASISTATIONARY MCS PERSISTS ACROSS SERN AL. VERY HEAVY RAIN
   HAS BEEN THE PRIMARY HAZARD WITH THIS FEATURE THE LAST FEW HOURS.
   CONVERGENCE AND LIFT ASSOCIATED WITH MODEST 15 KT SWLY 0-2 KM FLOW
   INTERSECTING THE NW-SE ORIENTED OUTFLOW BOUNDARY HAS RESULTED IN
   PERSISTENT DEVELOPMENT OF STORMS THAT SUBSEQUENTLY TRAIN SEWD UNDER
   THE INFLUENCE OF 15-20 KT NWLY FLOW ALOFT. THE MCS APPEARS TO BE
   TRANSITIONING FROM THE QUASI STEADY STATE...AND IS BECOMING MORE
   PROGRESSIVE. AS THE BOUNDARY LAYER CONTINUES TO
   DESTABILIZE...POTENTIAL FOR ISOLATED DAMAGING WIND MAY INCREASE AS
   THE STORMS BEGIN TO PROPAGATE SWD. FORECAST SOUNDINGS AS WELL AS WV
   IMAGERY IMPLY LARGE SCALE MID-UPPER LEVEL SUBSIDENCE MAY BE
   INCREASING OVER THE AREA IN WAKE OF UPPER TROUGH EXITING THE ERN
   SEABOARD. HOWEVER...CONVERGENCE ALONG LEADING OUTFLOW BOUNDARY MAY
   BE SUFFICIENT TO SUSTAIN STORMS THROUGH SERN AL AND SWRN GA NEXT FEW
   HOURS. OTHER MORE WIDELY SCATTERED ACTIVITY MAY BECOME CAPABLE OF
   PRODUCING ISOLATED DOWNBURSTS AND HAIL.
