   Areas affected...from the Laredo area eastward toward the middle to
   upper Texas Coast

   Concerning...Severe Thunderstorm Watch 233...

   Valid 200450Z - 200615Z

   The severe weather threat for Severe Thunderstorm Watch 233
   continues.

   SUMMARY...Isolated wind gusts over 50 kt remain possible across
   parts of southern into southeast Texas, within the broader zone of
   30-40 kt outflow.

   DISCUSSION...Within a broad W-E zone of thunderstorms, a few wind
   gusts over 50 kt have been measured, most recently at Kerrville TX
   with 56 kt. While most of the outflow as produced gusts of 30-40 kt,
   several larger/more organized storm clusters exist near intersecting
   outflow boundaries. The air mass remains quite moist, with modest
   southerly winds just above the surface aiding inflow (elevated above
   the outflow in some cases). 

   At this time it appears the overall severe risk will remain isolated
   across the entire region, with most gusts below 50 kt. However,
   trends will continue to be monitored as the system as a whole
   develops southeastward tonight.
