   AREAS AFFECTED...SOUTHEAST GA...SRN SC...NRN FL
   
   CONCERNING...TORNADO WATCH 4...
   
   VALID 051930Z - 052115Z
   
   CORRECTED FOR STATE IDENTIFIER MA TO MS
   
   A NEW TORNADO WATCH...ENCOMPASSING PARTS OF SERN GA/NRN FL...AND
   PERHAPS SRN SC...MAY BE NEEDED IN ABOUT AN HOUR.
   
   WIDESPREAD DEEP CONVECTION PERSISTS FROM THE NERN GULF OF MEXICO
   INLAND ACROSS THE FL PANHANDLE AND SRN/CNTRL GA THIS AFTERNOON. THIS
   ACTIVITY WAS WITHIN A ZONE OF VERY STRONG DEEP-LAYER ASCENT AHEAD OF
   A VIGOROUS SHORT WAVE TROUGH EJECTING NEWD ACROSS MS/AL. NRN PART OF
   THE LARGER SCALE QLCS....FROM NERN GA INTO NWRN SC...HAS RACED NEWD
   AHEAD OF THE SRN AREA OF WIDESPREAD TSTM ACTIVITY OVER SWRN GA AND
   FL. THE STRONG CONVECTION ACROSS THESE AREAS HAS BECOME INCREASINGLY
   EMBEDDED WITHIN LARGER RAIN SHIELD AND HAS LOST SOME LINEARITY OVER
   THE PAST FEW HOURS. HOWEVER... ISOLATED CELLS ARE OCCASIONALLY
   DEVELOPING AHEAD OF THE MCS AND HAVE SHOWN A TENDENCY TO ROTATE. A
   COUPLE OF THE MORE INTENSE CELLS AHEAD OF THE MCS WERE NOTED IN
   HOUSTON COUNTY GA...AND SOUTH OF FRANKLIN COUNTY FL...IN THE
   GULF...OVER THE PAST HOUR.
   
   WHILE IT APPEARS THAT DEEP CONVECTION MAY HAVE TEMPORARILY OUTRUN
   STRONGER FORCING ASSOCIATED WITH THE EJECTING UPPER WAVE...THE
   STRONG DRY PUNCH NOTED ON WATER VAPOR WILL SOON BEGIN TO OVERRUN
   STRONGER DIURNAL DESTABILIZATION OCCURRING ACROSS NRN FL AND SRN 
   GA. SHEAR ACROSS THESE AREAS IS EXPECTED TO REMAIN SUFFICIENTLY
   STRONG TO SUPPORT DAMAGING WINDS AND POSSIBLE TORNADOES INTO THE
   EVENING. THUS...EXPECT A NEW TORNADO WATCH MAY BE NEEDED SHORTLY.
