   Concerning...Severe Thunderstorm Watch 238...

   Valid 132320Z - 140045Z

   The severe weather threat for Severe Thunderstorm Watch 238
   continues.

   SUMMARY...Strong/locally severe storms continue across Deep South
   Texas in/near WW 238.  Expansion area of the WW may be appropriate,
   given potential for storms to exit the WW.

   DISCUSSION...Latest radar loop shows strong storms crossing Deep
   South Texas, largely within WW 238.  However, a few storms -- which
   have produced hail up to golfball size recently -- may near/move out
   of the southeastern fringe of the watch.  With a favorably unstable
   environment near/south of the front, a focus for ascent, and
   deep-layer shear supporting rotating storms, expect risk for large
   hail and damaging winds to continue.  This suggests consideration
   for an extension of the WW to cover additional counties within the
   WFO Brownsville area along the river, not currently in the watch.
