VALID 091803Z - 091930Z
THUNDERSTORMS EXPECTED TO INCREASE IN NUMBER AND INTENSITY ACROSS
SRN MS...SWRN AL...EXTREME WRN FL PANHANDLE AND SERN LA THROUGH THE
AFTERNOON HOURS. SOME STORMS MAY BRIEFLY PRODUCE STRONG/SEVERE WIND
GUSTS...BUT SHORT LIVED NATURE OF THE INDIVIDUAL STORMS INDICATES A
WATCH IS UNLIKELY.
STORMS OVER THE CENTRAL GULF COAST STATES ARE LOCATED WITHIN AN AXIS
OF VERY STRONG INSTABILITY...WITH MLCAPE VALUES IN EXCESS OF 3000
J/KG. HIGH PRESSURE CENTER ALOFT IS LOCATED ACROSS LA... RESULTING
IN THE NLY MID LEVEL WINDS...WHICH SHOULD PUSH STORMS SLOWLY SWD.
GIVEN THE STRONG INSTABILITY...VERY MOIST BOUNDARY LAYER AND
TEMPERATURES IN THE 90S...STRONG TO SEVERE WIND GUSTS WILL BE
POSSIBLE WITH THESE STORMS. DEEP LAYER SHEAR IS WEAK...SO ANY SEVERE
WIND GUSTS SHOULD BE SHORT LIVED. THE WIND THREAT SHOULD DIMINISH BY
EARLY EVENING AS THE STORMS MOVE OFFSHORE AND STORM OUTFLOWS
STABILIZE THE BOUNDARY LAYER.
