...NO SVR TSTM AREAS FORECAST...
...SE LA AND VICINITY TODAY...
THE CLOSED MIDLEVEL LOW OVER THE UPPER TX COAST WILL DRIFT
ESEWD/SEWD OVER THE NW GULF TODAY AND GRADUALLY EVOLVE INTO MORE OF
AN OPEN WAVE TONIGHT...AS AN UPSTREAM WAVE AMPLIFIES OVER THE GREAT
LAKES. A WEAK SURFACE CYCLONE ASSOCIATED WITH THE TX MIDLEVEL LOW
WILL LIKEWISE MOVE ESEWD FROM SE LA TO THE NE GULF MEXICO BY
TONIGHT. PRIOR TO THE LOW MOVING OFFSHORE...A NARROW SURFACE WARM
SECTOR /BENEATH THE MIDLEVEL DRY SLOT/ WILL BE MAINTAINED OVER SE LA
AND NEAR THE MS/AL/WRN FL PANHANDLE COASTS. GRADUALLY COOLING
MIDLEVEL TEMPERATURES...CONDITIONALLY UNSTABLE LAPSE RATES...AND
DAYTIME HEATING IN CLOUD BREAKS WILL CONTRIBUTE TO DESTABILIZATION
AND THE GENERATION OF MLCAPE VALUES OF 1000-1500 J/KG OVER SE LA IN
PROXIMITY TO THE MIDLEVEL COLD POOL. DEEP-LAYER SLY VERTICAL SHEAR
WILL ALSO SUPPORT SOME ORGANIZED/SUPERCELL STORM STRUCTURES...WHICH
COULD PROMOTE HAIL AND PRODUCTION IN THE STRONGER STORMS TODAY.
