   AREAS AFFECTED...SOUTH FL
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 302028Z - 302200Z
   
   THE THREAT FOR A FEW STRONG STORMS...AND POSSIBLY A SVR STORM OR TWO
   WITH DMGG WIND GUSTS...WILL PERSIST INTO LATE AFTERNOON ACROSS SOUTH
   FL.
   
   WITH GPS PW DATA DEPICTING ABUNDANT DEEP-LAYER MOISTURE ACROSS THE
   FL PENINSULA -- I.E. PWAT VALUES OF 2.0 TO 2.2 INCHES -- SCATTERED
   TO NUMEROUS STRONG TO SVR CONVECTION DEVELOPED ACROSS PORTIONS OF
   SOUTH FL EARLIER THIS AFTERNOON. ONE OUTFLOW BOUNDARY...EXTENDING
   FROM ERN PALM BEACH TO NWRN BROWARD TO SERN COLLIER COUNTIES...IS
   SURGING NWWD...WHILE ANOTHER OUTFLOW BOUNDARY OVER SRN MIAMI-DADE
   COUNTY IS SURGING SOUTHWARD. NEAR AND AHEAD OF THESE FEATURES...SFC
   CONVERGENCE COMBINED WITH A MODERATELY UNSTABLE AIR MASS WILL
   MAINTAIN A THREAT FOR STORMS WITH GUSTY WINDS TOWARD THE LAKE
   OKEECHOBEE AREA AND TOWARD THE SRN TIP OF THE FL PENINSULA THROUGH
   2200Z. THE THREAT FOR A DMGG WIND GUST OR TWO WILL PERSIST OWING TO
   WATER LOADING PROCESSES...WITH DMGG WINDS ALREADY HAVING BEEN
   REPORTED AROUND POMPANO BEACH IN BROWARD COUNTY. MEANWHILE...ONGOING
   CONVECTION BETWEEN THE AFOREMENTIONED BOUNDARIES WILL LIKELY BECOME
   INCREASINGLY ELEVATED ATOP THE CONVECTION-REINFORCING COLD
   POOL...WITH INCREASING SFC-BASED CONVECTIVE INHIBITION LIKELY
   MITIGATING THE THREAT FOR STRONG SFC WINDS. CONVECTIVE OVERTURNING
   IS EXPECTED TO HAVE LARGELY DIMINISHED THE THREAT FOR STRONG TO SVR
   STORMS BY 00Z PER CONSENSUS AMONGST CONVECTION-ALLOWING MODEL
   GUIDANCE.
