...SUMMARY...
ISOLATED THUNDERSTORMS WILL REMAIN POSSIBLE INTO THIS EVENING ACROSS
PARTS OF THE WESTERN AND CENTRAL GULF COAST STATES.

...WRN/CNTRL GULF COAST...
LOW-AMPLITUDE SHORTWAVE TROUGH OVER E TX WILL RAPIDLY PROGRESS E/NE
TOWARDS THE SRN APPALACHIANS THROUGH EARLY SAT. WITH ONLY MODEST
LOW-LEVEL WAA ATOP A NEAR-SURFACE STABLE LAYER AND THE REINFORCEMENT
OF STATIC STABILITY WITH A BROAD STRATIFORM RAINFALL
SHIELD...QUASI-STATIONARY FRONT ACROSS THE NW/N-CNTRL GULF SHOULD
REMAIN OFFSHORE EXCEPT NEAR THE MOUTH OF THE MS RIVER AS A WEAK
CYCLONE MOVES ALONG THE FRONTAL ZONE.

TSTM COVERAGE HAS ALREADY SUBSTANTIALLY DIMINISHED COMPARED TO
EARLIER THIS MORNING. GIVEN THE MODEST LARGE-SCALE ASCENT AND DEARTH
OF ELEVATED BUOYANCY/INSTABILITY SAMPLED IN 12Z LCH/SHV/LIX
RAOBS...PROSPECTS FOR INLAND TSTM ACTIVITY APPEAR RATHER LIMITED.
RENEWED TSTM DEVELOPMENT WILL REMAIN POSSIBLE ALONG THE OFFSHORE
FRONTAL ZONE...WITH THE NRN PERIPHERY OF SCANT BUOYANCY SUPPORTING A
RISK FOR SPORADIC LIGHTNING STRIKES OVER PARTS OF THE COASTAL PLAIN.
