...SERN TX...SRN LA...

MODIFYING GULF AIR WILL CONTINUE RETURNING NNEWD THROUGH TX AND THE
LOWER MS VALLEY TONIGHT ALONG LOW LEVEL JET. THE MOISTURE TRANSPORT
ABOVE THE COOL STABLE SURFACE MAY RESULT IN A SHALLOW CONVECTIVE
LAYER BETWEEN 900 AND 750 MB. ISENTROPIC LIFT AND MOISTURE
TRANSPORT ALONG THE LOW LEVEL JET WILL CONTINUE TO SUPPORT
SCATTERED SHOWERS TONIGHT OVER SERN TX INTO THE LOWER MS VALLEY.
HOWEVER...PRESENCE OF MID LEVEL INVERSION WILL INHIBIT THE
DEVELOPMENT OF DEEP CONVECTION. DEEPER ASCENT MAY DEVELOP LATER
TONIGHT AS SHORTWAVE TROUGH OVER NM APPROACHES THE AREA. THIS COULD
HELP WEAKEN THE CAP AND DESTABILIZE ATMOSPHERE THROUGH A DEEPER
LAYER. THOUGH AN ISOLATED ELEVATED STORM OR TWO COULD DEVELOP VERY
LATE TONIGHT...COVERAGE IS NOT EXPECTED TO BE SUFFICIENT TO WARRANT
INCLUDING IN AN OUTLOOK.
