   NWS STORM PREDICTION CENTER NORMAN OK

   AREAS AFFECTED...PORTIONS EXTREME SERN AL...SWRN GA...AND
   N-CENTRAL/NERN PANHANDLE OF FL.
   
   CONCERNING...HEAVY RAINFALL 
   
   VALID 061006Z - 061200Z
   
   HEAVY RAIN RATES 2-3 INCHES/HOUR ARE LIKELY TO CONTINUE FROM CORES
   IN MCS THAT SHOULD MOVE ESEWD FROM SERN AL ACROSS ADJACENT PORTIONS
   SWRN GA AND NRN/ERN FL PANHANDLE.
   
   TRAILING SEGMENT OF COMPLEX IS ELONGATING ALONG ITS AXIS OF
   MOTION...WHICH WILL LEAD TO PROLONGED TRAINING OF SUCH CORES.  THIS
   IN TURN WILL ENHANCE PRIMARY HAZARD OF HEAVY RAINFALL FROM
   COVINGTON/GENEVA COUNTIES AL...ESEWD ALONG PROJECTED MCS PATH ACROSS
   FL/GA BORDER REGION N OF TLH.  ADDITIONALLY...MCS MERGERS WITH
   MULTICELL TSTMS TO ITS S AND SE ARE LIKELY TO OCCUR OVER AREAS
   BETWEEN MAI...BGE AND TLH...FURTHER CONTRIBUTING TO RAINFALL THREAT.
    PROJECTED INFLOW LAYER AIR MASS IS VERY MOIST THROUGH DEEP
   LAYER...WITH PW 2-2.25 INCHES NEAR AND N OF I-10...BASED ON GPS DATA
   AND MODIFIED RUC SOUNDINGS.  SOME DRYING ALOFT IS EVIDENT  CLOSER TO
   IMMEDIATE COASTAL AREAS...HOWEVER.  MLCAPE 1000-1500 J/KG WILL BE
   MAINTAINED BY HIGH THETAE IN AND JUST ABOVE BOUNDARY LAYER...THOUGH
   BUOYANCY DOES APPEAR TO DIMINISH MARKEDLY FROM TLH AREA EWD.
   
   A FEW BRIEF/LOCALIZED DAMAGING GUSTS ALSO MAY OCCUR WITH BOW
   COMPOSING LEADING SEGMENT OF MCS...APEX REGION OF WHICH PRODUCED
   MEASURED GUSTS ONLY IN 26-36 KT RANGE AT SFC STATIONS OZR...HEY AND
   DHN.  THIS PORTION OF COMPLEX IS EXPECTED TO MOVE INTO PROGRESSIVELY
   STRONGER MLCINH EVIDENT OVER SWRN GA AND N-CENTRAL/NERN PANHANDLE OF
   FL.
