...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
SCATTERED THUNDERSTORMS MAY DEVELOP ACROSS PARTS OF THE CENTRAL GULF
COAST STATES SUNDAY.

...CENTRAL GULF STATES...

LOW-LATITUDE SHORT-WAVE TROUGH OVER THE BIG BEND REGION OF TEXAS IS
EXPECTED TO TRANSLATE EWD AND DE-AMPLIFY AS IT MOVES ACROSS THE
LOWER MS VALLEY INTO THE CNTRL GULF STATES.  THIS FEATURE...COMBINED
WITH WEAK WARM ADVECTION...SHOULD ENHANCE CONVECTIVE POTENTIAL FROM
THE LOWER MS VALLEY...NEWD ALONG/NORTH OF THE COLD FRONT INTO THE
SRN APPALACHIANS.  HOWEVER...BUOYANCY WILL BE QUITE LIMITED DUE TO
POOR LAPSE RATES AND MUCAPE WILL ONLY BE ON THE ORDER OF A FEW
HUNDRED J/KG.  GREATEST RISK FOR LIGHTNING WILL BE WITH CONVECTION
ASSOCIATED WITH FRONTAL ZONE AND PRIMARILY DURING THE FIRST 6-9HRS
OF THE PERIOD.
