   ...SYNOPSIS..
   UPPER LOW NOW OVER NW MEXICO EXPECTED TO CONTINUE SOUTHEAST ACROSS
   NRN MEXICO LATER TONIGHT...REACHING THE REGION S OF ELP BY 12Z
   FRIDAY.  AT LOWER LEVELS...FRONT EXPECTED TO REMAIN MORE OR LESS
   STATIONARY FROM E OF LRD NEWD TO BETWEEN CLL AND HOU.  A SECOND
   BOUNDARY...ATTM EXTENDING E ACROSS THE GULF FROM NEAR GLS/HOU...
   SHOULD CONTINUE SLOWLY N INTO SE TX/SRN LA AND COASTAL MS/AL BY THE
   END OF THE PERIOD.   
   
   ...SW TX...
   ELEVATED THUNDERSTORMS EXPECTED TO CONTINUE ACROSS PARTS OF SW TX
   THROUGH EARLY FRIDAY.  STORMS WILL BE ASSOCIATED WITH LARGE SCALE
   ASCENT IN NERN FRINGE OF MEXICAN UPPER LOW.  GIVEN COLDER AIR ALOFT
   NEAR THIS FEATURE AND SUSTAINED NATURE OF ASCENT...SOME OF THE
   STORMS COULD YIELD MARGINALLY SEVERE HAIL ALONG THE RIO GRANDE EWD
   INTO THE DAVIS MOUNTAINS. 
   
   ...CNTRL TX INTO ERN/NE TX AND LA...
   FARTHER E...WATER VAPOR IMAGERY AND EVENING SOUNDINGS SUGGEST THAT
   A PLUME OF ELEVATED MIXED LAYER AIR IS OVERSPREADING PARTS OF S
   CNTRL TX ATTM.  THIS PLUME SHOULD CONTINUE NEWD LATER TONIGHT/EARLY
   FRIDAY...ENHANCING CAP OVER S CNTRL AND FAR S TX.  STORMS SHOULD...
   HOWEVER...CONTINUE TO DEVELOP IN WARM ADVECTION ZONE N AND E OF
   ADVANCING PLUME...I.E. FROM CNTRL TX EWD INTO E TX AND LA.  THIS
   ACTIVITY MAY ALSO BE ENHANCED BY WEAK IMPULSE NOW MOVING ENE FROM
   BWD/SJT AREA.  MODEST ELEVATED INSTABILITY/CLOUD LAYER SHEAR
   PRESENT OVER REGION WILL BE SUPPORTIVE OF HAIL IN THE MORE
   SUSTAINED STORMS. 
   
   ...S CNTRL AND SE TX...
   A CONDITIONAL THREAT FOR SEVERE SURFACE-BASED STORMS WILL EXIST
   THROUGH EARLY FRIDAY ACROSS S TX...ALONG AND E OF STALLED FRONT
   ALONG THE COASTAL PLAIN.  A FEW STORMS MAY ALSO CONTINUE TO FORM
   INVOF SECOND BOUNDARY EXTENDING E ACROSS THE GULF FROM NEAR
   GLS/HOU.  AMPLE LOW AND DEEP LAYER SHEAR WILL BE PRESENT FOR
   SUPERCELLS...AND LOW LCLS WILL BE FAVORABLE FOR TORNADOES.  BUT
   GIVEN SEWD TRACK OF MEXICAN UPPER LOW...AND CONTINUED NEWD SPREAD 
   OF ELEVATED MIXED LAYER PLUME...POTENTIAL FOR STORM INITIATION IN
   THIS REGION WILL BE LIMITED.  ATTM...BELIEVE THAT GREATEST
   PROBABILITY FOR DEVELOPMENT WILL BE INVOF BOUNDARY NEAR
   GLS/HOU...WHERE STRONGER LOW LEVEL FORCING WILL EXIST.
