   AREAS AFFECTED...SE FLORIDA COAST
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 121936Z - 122030Z
   
   PROBABILITY OF WATCH ISSUANCE...5 PERCENT
   
   SUMMARY...SOME GUSTY WINDS ARE POSSIBLE WITH THUNDERSTORMS ACROSS
   THE SOUTHEAST FLORIDA COAST THE REMAINDER OF THE AFTERNOON.
   WIDESPREAD/ORGANIZED SEVERE THREAT IS NOT EXPECTED.
   
   DISCUSSION...THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON IN THE
   VICINITY OF A SEA BREEZE FRONT ACROSS SE FL. A MOIST AIRMASS
   CHARACTERIZED BY DEWPOINTS IN THE LOW TO MID 70S AND WARM
   TEMPERATURES IN THE MID TO UPPER 80S HAS RESULTED IN WEAK TO
   MODERATE INSTABILITY. POOR MIDLEVEL LAPSE RATES AND WEAK LOW TO MID
   LEVEL FLOW SHOULD LIMIT ORGANIZATION. HOWEVER...STEEP LOW LEVEL
   LAPSE RATES AND PW VALUES APPROACHING 1.75 INCHES COULD ALLOW FOR A
   FEW STRONGER GUSTS. ANY STORMS THAT DO DEVELOP WILL MOSTLY PRODUCE
   HEAVY RAIN AND SHOULD QUICKLY SHIFT OFFSHORE. THE LACK OF ORGANIZED
   CONVECTION AND SHORT TERM/LOW END THREAT WILL LIKELY PRECLUDE THE
   NEED OF A WW.
