   CORRECTED FOR WATCH TYPE IN HEADER
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 79 CONTINUES.
   
   ORGANIZED QLCS AND ATTENDANT MESOLOW /ANALYZED APPROXIMATELY 25 NW
   GNV/ HAVE SHIFTED ONSHORE THE W COAST OF FL. EMBEDDED CIRCULATIONS
   HAVE OCCASIONALLY BEEN OBSERVED WITHIN THIS LINE...BUT RECENT SFC
   OBSERVATIONS INDICATE SFC WINDS HAVE VEERED TOWARDS THE SW ACROSS
   THE CNTRL/NRN FL PENINSULA. THIS HAS RESULTED IN NEARLY
   UNIDIRECTIONAL AND WEAK LOW-LEVEL SHEAR PROFILES /GENERALLY 10-15
   KTS IN THE 0-1 KM LAYER PER VWP DATA/...AND COMBINED WITH
   PROPAGATION SPEEDS GENERALLY BETWEEN 35-45 KTS AND QUASI-LINEAR
   CONVECTIVE MODE...FAVORING A PRIMARY THREAT FOR DAMAGING WINDS.
   HOWEVER...A THREAT FOR BRIEF TORNADOES SHOULD PERSIST ALONG THE LINE
   BENEATH EMBEDDED STORM-SCALE CIRCULATIONS.  ALTHOUGH LOW-LEVEL
   CONVERGENCE HAS WEAKENED SOMEWHAT...AMPLE SOLAR INSOLATION ACROSS
   THE CNTRL PENINSULA HAS ALLOWED THE ENVIRONMENT TO SUFFICIENTLY
   DESTABILIZE /MLCAPE VALUES EXCEEDING 2000 J/KG/...AND SHOULD
   CONTINUE TO MAINTAIN DEEP CONVECTION AS IT PROPAGATES EWD ACROSS THE
   TOWARDS THE ERN FL PENINSULA.
