   Concerning...Severe Thunderstorm Watch 55...

   Valid 160441Z - 160645Z

   The severe weather threat for Severe Thunderstorm Watch 55
   continues.

   SUMMARY...A threat for large hail and wind damage is likely to
   continue for a few more hours across south Texas.

   DISCUSSION...The latest hi-resolution radar from Corpus Christi
   shows a large supercell to the southeast of Laredo. This storm is
   located along the northern edge of a pocket of moderate to strong
   instability, where the RAP has MLCAPE in the 2000 to 3000 J/kg
   range. The storm appears to be supported by a large-scale ascent
   associated with a subtle shortwave trough evident on water vapor
   imagery. Lift associated with the trough, steep mid-level lapse
   rates, and moderate deep-layer shear will likely continue to be
   favorable for a severe threat as this storm moves eastward across
   south Texas, and with additional cells that develop within the small
   cluster. A potential for large hail and wind damage is expected to
   persist for a few more hours.
