   SHORT WAVE TROUGH OVER OK AT 12Z MONDAY WILL TRANSLATE EWD ACROSS
   THE OH/TN VALLEYS ATOP A FLAT RIDGE EXTENDING FROM TX TO OFF THE
   SERN STATES.  UPSTREAM HEIGHT RISES FROM THE GREAT BASIN TO THE
   UPPER MS VALLEY WILL MAINTAIN CONFLUENT FLOW OVER THE CENTRAL
   PLAINS/LOWER MO VALLEY FOR SURFACE PRESSURE RISES TO DEVELOP SWD
   TOWARD TX.  ELEVATED THUNDERSTORMS ARE EXPECTED TO BE ONGOING AT THE
   START OF THE PERIOD ACROSS SRN/SERN TX WITHIN WEAK WAA REGIME. COLD
   FRONT WILL MOVE SEWD INTO THE NWRN GULF OF MEXICO TODAY...WITH THIS
   BOUNDARY NOT EXPECTED TO MOVE ESE OF BRO UNTIL LATE AFTERNOON. 
   THUNDERSTORMS ARE EXPECTED TO PERSIST THROUGH MUCH OF THE PERIOD
   ALONG AND NORTH OF THE COLD FRONT FROM S TX TO SRN LA...WITHIN
   CONTINUED ZONE OF WAA.
   
   50 KT OF SWLY MID LEVEL FLOW OVER THE TX COASTAL PLAIN TO LOWER MS
   VALLEY WOULD SUPPORT SUFFICIENT DEEP LAYER SHEAR FOR ORGANIZED
   STORMS IN THE WARM SECTOR.  HOWEVER...MODEST LAPSE RATES WILL TEND
   TO MINIMIZE AVAILABLE CAPE DESPITE SURFACE DEWPOINTS IN THE
   MID-UPPER 60S IN THE WARM SECTOR.  THUS...OVERALL POTENTIAL STORM
   INTENSITY/SEVERE THREAT IS EXPECTED TO BE LIMITED AS THE COLD FRONT
   MOVES SEWD ACROSS DEEP S TX BY LATE AFTERNOON.
