   AREAS AFFECTED...CNTRL/SRN FL PENINSULA
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 69...
   
   VALID 121133Z - 121300Z
   
   DAMAGING WIND POTENTIAL CONTINUES ACROSS ERN AND SRN PORTIONS OF WW
   69.
   
   REGIONAL RADAR MOSAIC INDICATES THAT BOWING SQUALL LINE HAS
   INTENSIFIED OVER THE PAST HALF HOUR AS IT MOVES EWD INTO THE CNTRL
   PENINSULA. LEADING EDGE OF COLD POOL CURRENTLY STRETCHES FROM 5N AGR
   TO 50E FMY TO 55SSE FMY WITH A CONTINUED EWD SYSTEM MOTION OF
   45-50KTS. LATEST RUC ANALYSIS FIELDS SUGGEST THAT CONVECTIVE LINE IS
   CURRENTLY MOVING INTO A PROGRESSIVELY MORE UNSTABLE AIRMASS IN PLACE
   ACROSS THE ERN PENINSULA WITH SBCAPES OF 1500-2500 J/KG.
   ADDITIONALLY...RUC FORECAST SOUNDINGS AND MIA VWP INDICATE
   SUFFICIENTLY STRONG LOW TO MID-LEVEL SHEAR PROFILES TO SUPPORT
   SMALLER-SCALE BOWS AND/OR EMBEDDED SUPERCELLS. GIVEN THE FAVORABLE
   SHEAR AND INSTABILITY PRESENT IN THE PRE-STORM ENVIRONMENT...EXPECT
   A CONTINUED THREAT OF PRIMARILY DAMAGING WINDS ACROSS THE ERN
   PENINSULA OVER THE NEXT HOUR OR TWO.
