   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 100
   CONTINUES.
   
   STORMS HAVE DEVELOPED ALONG THE RESIDUAL OUTFLOW BOUNDARY/
   DIFFERENTIAL HEATING ZONE ACROSS THE CENTRAL/NRN FL PENINSULA IN THE
   PAST 1-2 HOURS.  MODERATE INSTABILITY /MLCAPE OF 1500-2000 J/KG/ IS
   FEEDING THE CONVECTION ALONG THE BOUNDARY FROM THE SSW...WHILE
   LOW-LEVEL AND DEEP LAYER SHEAR REMAIN SUFFICIENT FOR SUPERCELLS
   ALONG THE BOUNDARY.  THE LARGER SCALE REGIME FAVORS LARGE HAIL AND
   DAMAGING WINDS AS THE PRIMARY SEVERE THREATS.  ON THE STORM
   SCALE...SUPERCELL INTERACTIONS WITH THE OUTFLOW BOUNDARY AND SEA
   BREEZE WILL ALLOW A SMALL WINDOW OF OPPORTUNITY FOR A TORNADO IN THE
   AREA IMMEDIATELY W OF CAPE CANAVERAL.  OTHERWISE...OTHER STORMS
   FORMING FARTHER WNW ALONG THE OUTFLOW BOUNDARY COULD DEVELOP
   SUPERCELL STRUCTURES IN THE NEXT COUPLE OF HOURS.  THE CLUSTER OF
   STORMS NEAR CTY COULD ALSO BEGIN TO PROPAGATE EWD/ESEWD ON THE COOL
   SIDE OF THE BOUNDARY...THOUGH WEAKER INSTABILITY WITH NWD EXTENT
   BRINGS THE SEVERE POTENTIAL WITH THESE STORMS IN QUESTION.
