   Areas affected...South TX

   Concerning...Severe Thunderstorm Watch 297...

   Valid 290241Z - 290345Z

   The severe weather threat for Severe Thunderstorm Watch 297

   SUMMARY...Isolated severe threat continues in the short term across
   the northwestern half of WW297.

   DISCUSSION...Thunderstorms have been slow to advance east across
   Webb/La Salle Counties this evening.  However, additional convection
   upstream is approaching this nearly stationary activity and some
   southeastward movement may occur over the next hour or so. 
   Considerable moisture/instability reside across south TX and an MCS
   may ultimately evolve across this region.
