   MODELS INDICATE LOW/MID-LEVEL CIRCULATION WILL CONTINUE TO DEVELOP
   IN THE VICINITY OF THE LOWER COLORADO VALLEY LATE THIS AFTERNOON AND
   TONIGHT.  AS THIS OCCURS...DOWNSTREAM MID-LEVEL FLOW REGIME IS
   PROGGED TO BECOME INCREASINGLY CONFLUENT/CONVERGENT OVER THE SOUTH
   CENTRAL PLAINS...WHERE SURFACE RIDGE WILL GRADUALLY BUILD.  THIS
   WILL BE ACCOMPANIED BY WEAK LOW-LEVEL FRONTOGENESIS BY THE EVENING
   HOURS FROM PARTS OF THE LOWER MISSISSIPPI VALLEY INTO SOUTH CENTRAL
   TEXAS AND THE RIO GRANDE VALLEY.
   
   FRONT WILL PROVIDE A ZONE OF ENHANCED LIFT...WHICH COULD BECOME
   FOCUS FOR WEAK THUNDERSTORM ACTIVITY.  BEST CHANCE FOR CONVECTION
   APPEARS TO BE EAST OF SAN ANTONIO/AUSTIN INTO THE LUFKIN/FORT POLK
   AREAS DURING THE MID/LATE EVENING HOURS.  MODELS SUGGEST
   LOWER/MID-LEVEL WARM ADVECTION JUST AHEAD OF BUILDING UPPER RIDGE
   MAY BRIEFLY CONTRIBUTE TO UPWARD VERTICAL MOTION ACROSS THIS
   REGION...BEFORE WEAKENING/SHIFTING EASTWARD OVERNIGHT.
