...THERE IS A SLGT RISK OF SVR TSTMS UPPER TX COAST ENEWD ACROSS THE
GULF COAST STATES...

...UPPER TX COAST EWD ACROSS THE GULF COAST STATES...
BAROCLINIC ZONE CURRENTLY EXTENDS FROM THE WRN CAROLINAS WSWWD
ACROSS NRN GA/CENTRAL AL/SRN MS AND INTO CENTRAL LA -- WHERE WEAK
WAVE HAS DEVELOPED ALONG FRONT.  WIDESPREAD CONVECTION -- INCLUDING
BOTH ELEVATED STORMS N OF SURFACE FRONT AND SURFACE-BASED STORMS
NEAR AND S OF BOUNDARY -- CONTINUES TO INCREASE IN COVERAGE FROM
SERN TX ENEWD INTO NRN GA.

WHILE INSTABILITY REMAINS LIMITED N OF FRONT SUGGESTING ONLY A
MARGINAL HAIL THREAT ACROSS THIS PORTION OF THE REGION...WARM MOIST
BOUNDARY LAYER ALONG AND S OF FRONT IS CONTRIBUTING TO AROUND 500
J/KG MEAN-LAYER CAPE.  DEGREE OF INSTABILITY -- COUPLED WITH
DEEP-LAYER SHEAR NEAR 60 KT ABOVE FRONTAL ZONE -- WILL CONTINUE TO
SUPPORT SEVERE/SUPERCELL STORMS THROUGH AT LEAST EARLY EVENING.

LOW-LEVEL VEERING/SHEAR REMAINS FAIRLY WEAK ACROSS THIS
REGION...SUGGESTING THAT ANY TORNADO POTENTIAL SHOULD REMAIN LOW. 
ATTM...IT APPEARS THAT HAIL SHOULD REMAIN THE PRIMARY SEVERE
THREAT...THOUGH LOCALLY-DAMAGING WINDS REMAIN POSSIBLE --
PARTICULARLY IF ORGANIZED/SMALL-SCALE LINE SEGMENTS OR BOWS CAN
FORM.  THIS SCENARIO WOULD APPEAR TO BE MOST LIKELY ACROSS CENTRAL
AND SRN LA...WHERE MOST WIDESPREAD CONVECTION -- AND THUS POTENTIAL
FOR COLD POOL DEVELOPMENT -- IS ONGOING ATTM INVOF WEAK SURFACE
WAVE.  THIS THREAT SHOULD SPREAD ACROSS PARTS OF SRN MS/SRN AL
THROUGH THIS EVENING...ALONG AND S OF FRONT.
