   AREAS AFFECTED...FAR SERN MS/THE SRN HALF OF AL/THE WRN FL PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 111536Z - 111700Z
   
   SHOWERS CROSSING SERN MS...SRN AL...AND THE WRN FL PANHANDLE MAY
   INTENSIFY SLOWLY OVER THE NEXT COUPLE OF HOURS...POSSIBLY REQUIRING
   TORNADO WATCH ISSUANCE.
   
   CURRENT RADAR IMAGERY REVEALS SEVERAL BROKEN LINES OF SHOWERS MOVING
   QUICKLY EWD ACROSS SERN MS/SRN AL AND THE FAR WRN FL PANHANDLE. 
   WHILE MORNING SOUNDINGS REVEAL WARM MID-LEVEL AIR WHICH IS HINDERING
   DEEPER CONVECTION/LIGHTNING...VERY STRONG LOW-LEVEL SHEAR IS
   PROMOTING UPDRAFT ROTATION PER LATEST VWPS.  
   
   CLOUD COVER SHOULD LIMIT HEATING...AND THUS THE POTENTIAL FOR
   DESTABILIZATION.  HOWEVER...AS MID-LEVEL COOLING SPREADS
   EWD...DEEPER CAPE -- SUFFICIENT FOR TALLER AND PERHAPS EVEN
   LIGHTNING-PRODUCING UPDRAFTS -- COULD EVOLVE.  WHILE LITTLE THREAT
   FOR ANY MORE THAN A BRIEF/WEAK TORNADO SPIN-UP EXISTS ATTM...WE WILL
   CONTINUE TO MONITOR THIS AREA FOR SIGNS OF DESTABILIZATION AND
   CORRESPONDINGLY DEEPER/MORE INTENSE CONVECTION WHICH WOULD THEN
   REQUIRE TORNADO WATCH ISSUANCE.
