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.
