A SHORTWAVE TROUGH OVER THE LOWER RIO GRANDE VALLEY WILL EJECT NEWD
TO THE LOWER MS VALLEY AND LOSE AMPLITUDE...AS AN UPSTREAM LOW OVER
THE NRN INTERMOUNTAIN WEST DIGS ESEWD. A SURFACE LOW JUST OFF THE
MIDDLE TX COAST AND AN ASSOCIATED BOWING MCS BOTH APPEAR TO HAVE
PASSED PEAK. THE LOW SHOULD CONTINUE TO SLOWLY WEAKEN DURING THE
DAY AND INTO TONIGHT AS THE MIDLEVEL TROUGH NO LONGER PHASES WITH
THE COASTAL FRONT. THE SEVERE STORM THREAT IS ENDING ALONG THE TX
COAST...BUT THERE WILL BE A SMALL WINDOW OF OPPORTUNITY FOR DAMAGING
GUSTS AND EMBEDDED ROTATING STORMS ALONG THE SE LA COAST LATER THIS
AFTERNOON/EVENING WITH CLOSEST APPROACH OF THE LOW AND SURFACE WARM

STRONG WAA REGIME COULD SUPPORT A FEW ELEVATED THUNDERSTORMS WITH
MIXED WINTER PRECIPITATION TONIGHT AS FAR N AS THE I-20 CORRIDOR
FROM MS INTO GA.
