   MESOSCALE DISCUSSION 0401
   NWS STORM PREDICTION CENTER NORMAN OK
   0329 PM CDT MON APR 20 2015

   AREAS AFFECTED...CNTRL AND ERN FL

   CONCERNING...SEVERE THUNDERSTORM WATCH 87...

   VALID 202029Z - 202230Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 87
   CONTINUES.

   SUMMARY...LOCALIZED SEVERE WIND AND HAIL THREAT TO PERSIST FOR A FEW
   MORE HOURS.

   DISCUSSION...NUMEROUS STORMS PERSIST ACROSS THE ERN HALF OF THE FL
   PENINSULA NEAR A LOW PRESSURE TROUGH. GIVEN THE VEERING LOW-LEVEL
   WINDS AND UPSTREAM CLEARING/HEATING...THESE STORMS CONTINUE TO
   REFORM AND ARE EXPECTED TO PERSIST FOR SEVERAL MORE HOURS GIVEN
   AVAILABLE MOISTURE AND INSTABILITY. STRONG MID TO UPPER LEVEL WINDS
   ARE LIKELY AIDING IN PARTICLE EVACUATION AND MAY BE MINIMIZING COLD
   POOLS WHICH ORDINARILY WOULD LIMIT STORM LONGEVITY.

   MEANWHILE TO THE W...OTHER STORMS WERE APPROACHING THE TAMPA AREA
   WITH RECENT INDICATIONS OF NEAR-SEVERE WINDS. HOWEVER...THE SEVERE
   THREAT HERE IS EXPECTED TO BE LOCALIZED.
