   ...CENTRAL/SRN TX...
   SHORTWAVE TROUGH WHICH HAS AIDED THUNDERSTORM DEVELOPMENT LAST
   NIGHT/THIS MORNING ACROSS CENTRAL TX WILL CONTINUE TO WEAKEN AS IT
   SHIFTS EWD INTO THE MID-SOUTH TODAY.  LEADING EDGE OF CONVECTION NOW
   MOVING INTO THE TX COASTAL PLAIN WILL MOVE OFFSHORE...THOUGH 
   OUTFLOW/SURFACE FRONT ASSOCIATED WITH THIS ACTIVITY WILL LIKELY
   REMAIN STALLED IN AN E-W FASHION FROM THE COASTAL BEND REGION INTO
   THE RIO GRANDE VALLEY. SRN STREAM REMAINS ACROSS SOUTH TX WITH
   MODEST WLY MID/UPPER LEVEL FLOW...WHILE WEAK SRN STREAM IMPULSE NOW
   MOVING ACROSS NRN MEXICO MAY BE ABLE TO AID DEVELOPMENT OF A FEW
   THUNDERSTORMS LATER TODAY AND THIS EVENING.  MITIGATING FACTOR FOR
   RENEWED DEVELOPMENT THIS AFTERNOON WILL BE THE MARGINAL
   INSTABILITY...GIVEN THE EXTENSIVE CLOUDINESS AND ONLY MODEST GULF
   MOISTURE RETURN.  HOWEVER...SHEAR WILL REMAIN SUFFICIENT FOR A LOW
   PROBABILITY THREAT OF SEVERE THUNDERSTORMS SHOULD NEW STORMS
   DEVELOP.
