   VALID 241517Z - 241615Z
   
   THUNDERSTORMS ARE ONGOING OVER THE SERN PENINSULA...BUT WILL BECOME
   MORE WIDESPREAD ACROSS THE REMAINDER OF THE PENINSULA BY EARLY
   AFTERNOON. PRIMARY THREATS OF MARGINAL HAIL/WIND AND HEAVY RAINFALL
   CAN BE EXPECTED. DUE TO THE DISORGANIZED/MARGINAL NATURE OF THE
   CONVECTION...A WW IS NOT CURRENTLY ANTICIPATED.
   
   CU FIELD HAS BEEN INCREASING ACROSS FL THIS MORNING...WHILE A WEST
   COAST SEA BREEZE HAS BEGUN TO PUSH INLAND...PRIMARILY FROM NEAR
   TAMPA SWD. ALONG THE EAST COAST...THE SEA BREEZE HAS BEEN SOMEWHAT
   MODIFIED FROM OFFSHORE CONVECTION. HOWEVER...GIVEN HOT
   TEMPERATURES/DEW POINTS IN THE LOWER 70S BEHIND THE OUTFLOW...THE
   SEA BREEZE WILL ONLY BE SHORTLY DELAYED. 12Z SOUNDINGS APPEAR VERY
   FAVORABLE FOR WIDESPREAD CONVECTION...WITH -10 TO -11 C AT 500
   MB...AND RELATIVELY STEEP LOW AND MID LEVEL LAPSE RATES. AS AMPLE
   HEATING ERODES REMAINING CINH...THE ATMOSPHERE WILL QUICKLY
   DESTABILIZE...WITH 1500 TO 2000 J/KG MLCAPE PER 12Z SOUNDINGS
   COMMON. ALTHOUGH CONVECTION WILL PRIMARILY BE FOCUSED OVER INLAND
   PORTIONS OF THE PENINSULA...OUTFLOW BOUNDARIES WILL BE CONDUCIVE TO
   RENEWED DEVELOPMENT ELSEWHERE. LIGHT FLOW AND HIGH PWATS WILL BE
   FAVORABLE FOR HEAVY RAINFALL IN NEARLY STATIONARY STORMS. MARGINAL
   HAIL/WIND AND ISOLD SEVERE CAN BE ANTICIPATED.
