...NO SVR TSTM AREAS FORECAST...
THE PERSISTENT UPPER LOW OVER THE TX/LA COAST WILL CONTINUE TO DRIFT
SLOWLY EASTWARD INTO THE WESTERN GULF OF MEXICO TODAY. THE PRIMARY
SURFACE BOUNDARY WILL ALSO CONTINUE IT SLOW EASTWARD PROGRESS ACROSS
SOUTHERN LA/MS/AL AND INTO WESTERN FL BY THU MORNING. SCATTERED
THUNDERSTORMS ARE OCCURRING ALONG THE BOUNDARY...WHERE SUFFICIENT
VERTICAL SHEAR IS PRESENT FOR TRANSIENT ROTATING STORMS CAPABLE OF
GUSTY WINDS. WEAK SURFACE-BASED CAPE AND POOR LAPSE RATES ARE
EXPECTED TO LIMIT THE THREAT OF ORGANIZED SEVERE STORMS.
LATER THIS AFTERNOON...BREAKS IN THE CLOUDS WILL PROMOTE MODEST
HEATING OVER SOUTHEAST LA. MARGINAL INSTABILITY IS EXPECTED TO
DEVELOP DESPITE WEAK LOW LEVEL DRY ADVECTION. ISOLATED
THUNDERSTORMS MAY DEVELOP IN THIS POST-FRONTAL ENVIRONMENT. COOLING
TEMPERATURES ALOFT WILL SUPPORT A RISK OF HAIL AND GUSTY WINDS IN
THE STRONGEST STORMS. SEVERE ACTIVITY IS NOT EXPECTED.
