   Concerning...Severe Thunderstorm Watch 179...

   Valid 050345Z - 050515Z

   The severe weather threat for Severe Thunderstorm Watch 179
   continues.

   SUMMARY...Risk for large hail and damaging winds continues over
   portions of southern Texas.

   DISCUSSION...Latest radar loop shows a cluster of strong/severe
   convection just west of the Hondo, TX vicinity at this time -- i.e.
   crossing portions of WW 179.  The strongest storms are ongoing over
   northwestern Medina County, and northern Zavala/far southern Uvalde
   Counties at this time.  The Medina county convection is particularly
   well-organized, and has exhibited small-scale bowing with dual
   book-end vortices within recent radar imagery -- suggestive of
   damaging wind potential.

   An axis of 2000 J/kg mixed-layer CAPE resides across the area at
   this time, and with southeasterly low-level winds veering to
   southwesterly aloft, shear favors both storm organization as well as
   a continued east-northeasterly advance, that will allow the
   convection -- and accompanying severe risk -- to approach the San
   Antonio metro area over the next 1 to 1 1/2 hours.
