   Areas affected...West-central Texas

   Concerning...Severe Thunderstorm Watch 154...

   Valid 250320Z - 250500Z


   The severe weather threat for Severe Thunderstorm Watch 154

   SUMMARY...A severe threat will likely continue across parts of
   west-central Texas over the next few hours. Large hail and wind
   damage will be the primary hazards. The severe threat should
   gradually become more isolated late this evening. New watch issuance
   appears unlikely.

   DISCUSSION...The latest high-resolution radar from Del Rio has a
   small cluster of severe thunderstorms about 70 statute miles
   southwest of San Angelo. The storms are located along an
   east-to-west front where low-level convergence is maximized. Surface
   dewpoints in the lower 60s F to the south of the boundary are
   contributing to moderate instability, with the RAP estimating MLCAPE
   in the 2000 to 2500 J/kg range. In addition, an upper-level trough
   is evident on water vapor imagery over the southern Rockies
   extending southward into far West Texas. Large-scale ascent and
   moderate deep-layer shear associated with the trough will support
   continued thunderstorm development over parts of west-central Texas
   late this evening. The deep-layer shear combined with steep
   mid-level lapse rates will support large hail with storms that can
   maintain supercell structure. Wind damage will also be possible, but
   any threat should gradually become more isolated late this evening.
