   GEN TSTMS ARE FCST TO THE RIGHT OF A LINE FROM 20 ESE CRP 40 SSW ALI

   ...NO SVR TSTM AREAS FORECAST...
   
   ...TX TO WRN LA...
   SHORT WAVE TROUGH LOCATED OVER NM WILL WEAKEN OVERNIGHT AS IT SHEARS
   ENEWD ACROSS THE SRN PLAINS.  THE LACK OF SIGNIFICANT HEIGHT FALLS
   EXPECTED ACROSS THE ERN HALF OF TX WILL RESULT IN LOW LEVEL WAA
   REMAINING THE MAIN FORCING MECHANISM FOR ELEVATED THUNDERSTORMS THIS
   FORECAST PERIOD.  EARLY EVENING SURFACE ANALYSIS SHOWED THE PRIMARY
   SYNOPTIC BOUNDARY EXTENDED FROM DEEP S TX NEWD INTO THE NWRN AND NRN
   GULF...WHILE AN INVERTED TROUGH WAS ANALYZED ALONG AND NEAR A LINE
   FROM MFE TO AUS TO PRX TO SERN OK.
   
   DESPITE AN EXTENSIVE AREA OF CONVECTIVE CLOUDS EXTENDING FROM DEEP S
   TX NNEWD TO ERN OK PER LATE AFTERNOON VIS IMAGERY...EMBEDDED TSTMS
   WERE CONCENTRATED IN AN AREA WHERE THE 35 KT SLY LLJ INTERSECTED AN
   E-W ORIENTED 850 MB THERMAL GRADIENT OVER NRN TX.  THIS LOW-LEVEL
   BOUNDARY AND THE INVERTED SURFACE TROUGH ARE EXPECTED TO SETTLE
   SSEWD OVERNIGHT...WITH THE LLJ VEERING TO SWLY AS THE UPPER TROUGH
   TRANSLATES ENEWD.  THUS...THUNDERSTORM POTENTIAL SHOULD DEVELOP
   SSEWD TOWARD THE MIDDLE TX COAST AND WRN LA WITHIN STRONGEST WAA.
   
   ...WEST CENTRAL TX...
   A COUPLE OF STRONG TO SEVERE STORMS DEVELOPED AFTER 23Z NEAR THE
   NM/TX BORDER.  THESE STORMS DEVELOPED AHEAD OF THE SHORT WAVE TROUGH
   WHERE UVVS WERE MAXIMIZED AND THE COMBINATION OF WEAK LOW LEVEL
   WAA...COLD MID LEVEL TEMPERATURES...SUFFICIENT DEEP LAYER SHEAR AND
   VERY LOW WET-BULB ZERO TEMPERATURES RESULTED IN GOLF BALL SIZE HAIL.
   THE LOSS OF DAYTIME HEATING CONTINUING TO STABILIZE THE BOUNDARY
   LAYER THIS EVENING AND DECREASING WAA ARE EXPECTED TO LIMIT THE
   POTENTIAL FOR ADDITIONAL DEEP CONVECTION AFTER 02Z.  GIVEN THE SMALL
   COVERAGE AREA AND SHORT DURATION OF A SEVERE AND GENERAL TSTM
   THREAT...SEVERE PROBABILITIES FOR HAIL AND A CATEGORICAL
   THUNDERSTORM OUTLOOK WILL NOT BE ADDED FOR THIS AREA.
