   The severe weather threat for Severe Thunderstorm Watch 293

   SUMMARY...Strong/severe thunderstorms will continue across WW293.

   DISCUSSION...An elongated corridor of robust convection persists
   from near DRT-25N AUS-TYR.  This activity has evolved along a
   pronounced cold front that should gradually sag southward over the
   next few hours.  In addition, water vapor imagery suggests an upper
   shortwave-trough is oriented southwest-northeast along this axis of
   convection and as this trough shifts east veering deep-layer flow in
   its wake should encourage storms across south-central TX to
   propagate south.  Large hail is the primary risk with this activity.
