   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

   WEAK CONVECTIVE DEVELOPMENT IS UNDERWAY ACROSS INTERIOR INTO EAST
   CENTRAL COASTAL SECTIONS OF THE FLORIDA PENINSULA.  THIS IS
   GENERALLY OCCURRING ALONG AND EAST OF A PRE-FRONTAL SURFACE TROUGH
   ...AS BOUNDARY LAYER HEATING AND MOISTENING CONTRIBUTES TO WEAKENING
   MID-LEVEL INHIBITION.  AS A SIGNIFICANT SHORT WAVE IMPULSE CONTINUES
   TO LIFT NORTHEASTWARD TO THE LEE OF THE APPALACHIANS...VEERING OF
   LOW-LEVEL FLOW FIELDS IS EXPECTED TO FOCUS LOW-LEVEL CONVERGENCE
   NEAR/EAST OF LAKE OKEECHOBEE INTO THE VERO BEACH AND PALM BEACH
   AREAS BY 20-22Z.  IN THE PRESENCE OF MODERATELY STRONG
   DESTABILIZATION...WITH MIXED LAYER CAPE NOW INCREASING IN EXCESS OF
   1000 J/KG...THIS MAY BECOME SUFFICIENT TO SUPPORT THE DEVELOPMENT OF
   ISOLATED TO SCATTERED THUNDERSTORMS.  IF THIS OCCURS...RELATIVE COOL
   MID LEVEL TEMPERATURES AND SHEAR BENEATH 30+ KT 500 MB FLOW COULD
   PROMOTE THE RISK FOR HAIL.  ALTHOUGH PROBABILITIES ARE LOW...THE
   POTENTIAL THAT SOME OF THIS ACTIVITY COULD AT LEAST BRIEFLY EXCEED
   SEVERE LIMITS MAY NOT BE COMPLETELY NEGLIGIBLE.
