0152 PM CDT FRI MAR 25 2016
AREAS AFFECTED...SERN FL
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 251852Z - 252115Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...ISOLATED STRONG TO SEVERE STORMS ARE EXPECTED TO AFFECT
PORTIONS OF SERN AND E CNTRL FL LATER TODAY...WITH LARGE HAIL AND
LOCALIZED WIND DAMAGE POSSIBLE.
DISCUSSION...AN E-W BOUNDARY CURRENTLY EXISTS ACROSS SRN FL AND IS
GRADUALLY LIFTING/MIXING NWD WITH AN INFLUX OF NEAR 70 F DEWPOINTS.
MEANWHILE...TEMPERATURES CONTINUE TO WARM INTO THE 80S WHICH SHOULD
ALLOW FOR PARCELS TO EASILY REACH THE LFC GIVEN SUFFICIENT LIFT.
DEEPER CONVECTION IS ALREADY DEVELOPING ALONG THE E COAST SEA BREEZE
AND INTERSECTION OF THE MAIN FRONT. WITH TIME...A FEW RELATIVELY
HIGH-TOPPED STORMS WILL DEVELOP...SUPPORTED BY FAVORABLE LAPSE RATES
ALOFT AND MODEST MID TO UPPER LEVEL SHEAR. WEAK WINDS IN THE
LOW-LEVELS SUGGEST PERHAPS SPLITTING CELLS...AND HAIL WILL BE A
DISTINCT POSSIBILITY. COLD DOWNDRAFTS MAY ALSO YIELD LOCALIZED WIND
DAMAGE. AT THIS TIME...SEVERE COVERAGE IS EXPECTED TO BE TOO SPARSE
FOR A WATCH.
