   ...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF CENTRAL AND SRN
   TX EWD INTO SRN LA...
   
   ...SYNOPSIS...
   VORT MAX MOVING ACROSS WRN AND INTO CENTRAL TX ATTM -- WITHIN
   BROADER SHORT-WAVE TROUGH OVER THE SRN PLAINS / NRN MEXICO -- WILL
   CONTINUE EWD ACROSS TX TOWARD THE WRN GULF.  ASSOCIATED LARGE-SCALE
   UVV AND PRESENCE OF STALLING FRONT ACROSS CENTRAL TX WILL CONTRIBUTE
   TO SEVERE CONVECTIVE DEVELOPMENT THIS AFTERNOON AND EVENING.  
   
   ...S TX / THE HILL COUNTRY ENEWD INTO SRN LA...
   INITIAL CLUSTER OF STRONG / SEVERE STORMS HAS DEVELOPED JUST S OF
   JCT...WITH STORMS FORECAST TO INCREASE EWD / SEWD ACROSS PARTS OF
   SRN / SERN TX THIS AFTERNOON AHEAD OF UPPER SHORT-WAVE TROUGH. 
   HEATING OF BOUNDARY-LAYER AIRMASS SHOULD CONTINUE...WHICH ALONG WITH
   COMBINATION OF DEWPOINTS GENERALLY IN THE LOW 60S AND STEEP
   MID-LEVEL LAPSE RATES SHOULD SUPPORT A LARGE AREA OF 1000 TO 2000
   J/KG MEAN-LAYER CAPE ACROSS MUCH OF THIS REGION INTO THIS EVENING.
   
   THOUGH FAIRLY WEAK LOW-LEVEL FLOW SUGGESTS THAT TORNADO THREAT WILL
   REMAIN LIMITED...DEEP-LAYER SHEAR IS SUFFICIENT FOR ORGANIZED /
   SUPERCELL STORMS.  RESULTING POTENTIAL FOR STRONG UPDRAFTS WITHIN
   RELATIVELY COOL LOWER TO MID TROPOSPHERE SUGGEST THAT LARGE HAIL CAN
   BE EXPECTED -- INCLUDING SOME POTENTIAL FOR HAILSTONES IN EXCESS OF
   2" IN DIAMETER.  LATER THIS AFTERNOON / EVENING...STORMS MAY EVOLVE
   INTO AN MCS OVER SERN TX -- POSSIBLY ACCOMPANIED BY LOCALLY DAMAGING
   WINDS IN ADDITION TO ONGOING HAIL THREAT.  THOUGH LESSER CHANCE FOR
   SEVERE STORM DEVELOPMENT EXISTS ACROSS PARTS OF SRN LA THIS
   AFTERNOON...MCS ALONG WITH SOME SEVERE THREAT SHOULD SPREAD EWD
   ACROSS THE SABINE RIVER INTO SRN LA OVERNIGHT.
