   Areas affected...South Texas and Texas Coastal Plains

   Concerning...Severe Thunderstorm Watch 224...225...

   Valid 250423Z - 250630Z

   The severe weather threat for Severe Thunderstorm Watch 224, 225
   continues.

   SUMMARY...A wind damage and isolated large hail is expected to
   continue into the overnight period across south Texas and the middle
   Texas Coastal Plain.

   DISCUSSION...Latest radar imagery shows a well-developed linear MCS
   from near the Rio Grande extending northward into eastern sections
   of the Texas Hill Country. The large-scale bow and associated cold
   pool is moving into a strongly unstable airmass with the RAP
   estimating MLCAPE along the lower to middle Texas Coast in the 2500
   to 3000 J/kg range. The line is being forced by an upper-level
   trough and associated mid-level speed max moving through southwest
   Texas. The line will continue eastward the Texas Coast and should
   affect far south Texas where the instability and moderate deep-layer
   shear should keep a wind damage threat going. An isolated tornado
   and large hail threat will also be possible within rotating cells
   embedded in the line.
