SPC MESOSCALE DISCUSSION 1466 FOR CNTRL PORTIONS OF THE NRN/CNTRL
   PEN OF FL
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 251858Z - 252230Z
   
   TREND TOWARD GREATER TSTM COVERAGE THAN YESTERDAY IS UNDERWAY
   ACROSS PORTIONS OF FL.  COLLIDING BOUNDARIES WILL LIKELY AID IN
   ADDITIONAL INITIATION ACROSS INTERIOR PORTIONS OF THE NRN/CNTRL FL
   PEN AFTER 20 UTC.  A FEW STORMS WILL LIKELY PRODUCE DAMAGING
   WINDS/HAIL...BUT SPARSE COVERAGE WILL PRECLUDE WW ISSUANCE.
   
   RECENT RADAR/SATELLITE IMAGERY SHOWS TSTM CLUSTER DEVELOPING OVER
   ERN LEVY AND ERN CITRUS COUNTIES NEAR WEST COAST SEABREEZE. 
   OUTFLOW EMANATING FROM THIS CLUSTER WILL LIKELY SPREAD EWD AND
   COLLIDE WITH EAST COAST SEABREEZE LATER THIS AFTERNOON.  12 UTC
   TPA/JAX SOUNDINGS INDICATE COLDER THAN NORMAL 5H TEMPERATURES
   AROUND MINUS 10 ATOP VERY MOIST BOUNDARY LAYER.  THIS SUGGESTS A
   GREATER PROBABILITY OF ISOLD DAMAGING WINDS/HAIL WITH SUSTAINED
   UPDRAFTS.  THE MAJORITY OF THE TSTMS ARE LIKELY TO OCCUR NORTH OF
   WINTER HAVEN...RUNNING NWD TOWARD LEESBURG AND GAINESVILLE.
   ACTIVITY WILL PERSIST INTO THE EARLY EVENING HOURS BEFORE
   DIMINISHING AFTER SUNSET.
