   AREAS AFFECTED...SRN FL PENINSULA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 282149Z - 282245Z
   
   ISOLATED STRONG STORMS WILL BE POSSIBLE ACROSS PORTIONS OF THE SRN
   FL PENINSULA THROUGH 00Z. A WW IS NOT NECESSARY.
   
   PERSISTENT NUMEROUS CONVECTION OVER THE CNTRL FL PENINSULA HAS
   RESULTED IN AN EXPANSIVE COLD POOL THAT FOLLOWS A SWWD-MOVING
   OUTFLOW BOUNDARY THAT EXTENDS FROM 35 MILES NW OF FMY TO MIA.
   MODERATE SWLY FLOW ATOP THIS COLD POOL IS INDUCING ISENTROPIC
   ASCENT...WITH SCATTERED CONVECTION CONTINUOUSLY REGENERATING ALONG
   AND JUST BEHIND THE OUTFLOW BOUNDARY. DEEPER/MORE PERSISTENT CORES
   HAVE BEEN NOTED ACROSS BROWARD COUNTY...AND THIS ACTIVITY WILL
   LIKELY TRANSLATE FARTHER SOUTH TOWARD METRO MIAMI IN CONJUNCTION
   WITH THE MOTION OF THE OUTFLOW BOUNDARY. RUC OBJECTIVE ANALYSIS
   INDICATES A MODERATELY UNSTABLE AIR MASS /MLCAPE VALUES FROM 1000 TO
   2000 J PER KG/ NEAR AND AHEAD OF THE OUTFLOW BOUNDARY...WITH STRONG
   MID-LEVEL FLOW PROMOTING CLOUD-BEARING SHEAR MAGNITUDES OF 50 TO 60
   KT. THESE PARAMETERS COULD PROMOTE OCCASIONALLY ORGANIZED STORM
   STRUCTURES...WITH THE POTENTIAL FOR STRONG WIND GUSTS AND POSSIBLY
   SMALL HAIL...ESPECIALLY AS THE OUTFLOW BOUNDARY MERGES WITH THE SEA
   BREEZE GENERATED OFF THE SWRN FL COAST. WHILE AN ISOLATED SEVERE
   STORM CANNOT BE ENTIRELY RULED OUT...THE ABSENCE OF STRONGER
   DEEP-LAYER FORCING WILL LIKELY PRECLUDE A GREATER THREAT FOR
   ORGANIZED SEVERE STORMS...AND THUS A WW IS NOT NECESSARY. AFTER
   00Z...STORMS WILL LIKELY WEAKEN AS DIABATIC COOLING COMMENCES.
