   FLORIDA AND THE FL PANHANDLE

   CONCERNING...SEVERE THUNDERSTORM WATCH 247...

   VALID 070156Z - 070330Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 247

   SUMMARY...STORMS MAY REMAIN STRONG TO SEVERE INTO THE FLORIDA BORDER
   AREA... PERHAPS THE INTERSTATE 10 CORRIDOR...THROUGH 03-04Z...BEFORE
   DIMINISHING MORE RAPIDLY.

   DISCUSSION...RECENT LIGHTNING AND WDSS-II CAPPI DATA SUGGEST A
   WEAKENING TREND TO THUNDERSTORM ACTIVITY MAY NOW BE UNDERWAY ALONG A
   SOUTHWARD ADVANCING CONGLOMERATE SURFACE COLD POOL.  HOWEVER...A
   RISK FOR STRONG WINDS AT LEAST APPROACHING SEVERE LIMITS MAY
   CONTINUE ALONG THE GUST FRONT FOR ANOTHER HOUR OR TWO...UNTIL IT
   PROGRESSES ACROSS THE FLORIDA BORDER INTO THE INTERSTATE 10 CORRIDOR
   OF NORTHERN FLORIDA DURING THE 03-04Z TIME FRAME.  THEREAFTER...AS
   THE GUST FRONT BEGINS TO ENCOUNTER COOLER BOUNDARY LAYER AIR /AND
   THE TEMPERATURE GRADIENT ACROSS THE GUST FRONT DECREASES/ THIS
   THREAT SHOULD DIMINISH.  AS INHIBITION ALSO BEGINS TO INCREASE WITH
   BOUNDARY LAYER COOLING...INTENSITY OF THUNDERSTORM ACTIVITY PROBABLY
   WILL DIMINISH AS WELL.
