   STRONG SURFACE COLD POOL ON SOUTHERN FLANK OF LINEAR MESOSCALE
   CONVECTIVE SYSTEM IS NOW SURGING SOUTH SOUTHEASTWARD INTO THE LOWER
   RIO GRANDE VALLEY.  STRONGEST SYSTEM RELATIVE INFLOW/CONVERGENCE IS
   FOCUSED ACROSS THE LAREDO AREA...BUT COOLER MORE STABLE BOUNDARY
   LAYER EAST OF THE RIVER...ACROSS MUCH OF DEEP SOUTH TEXAS...SEEMS
   LIKELY TO PRECLUDE MAINTENANCE OF VIGOROUS CONVECTIVE DEVELOPMENT.

   POOL INTO THE BROWNSVILLE AREA BY 06Z...BUT THE MOST SIGNIFICANT
   THUNDERSTORM ACTIVITY ALREADY APPEARS TO BE IN THE PROCESS OF
