   Areas affected...A small part of south central and southeast TX

   Concerning...Severe potential...Watch unlikely 

   Valid 022215Z - 022345Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A low-end supercell environment will persist the next few
   hours as storms spread slowly eastward near and just north of I-10
   between San Antonio and Houston.

   DISCUSSION...Storms have developed some weak supercell structures
   the past 1-2 hours to the east of San Antonio, along the east edge
   of modest surface-based buoyancy.  The storms are being driven
   largely by low-level warm advection, which will persist into the
   evening, and contribute to sufficient deep-layer vertical shear and
   hodograph curvature for supercells.  However, with eastward extent,
   the storms will likely become more elevated with time on the east
   edge of the richer low-level moisture.  While some hail cannot be
   ruled out in the short term, the longer-term threat for severe
   weather will be limited by the weakening buoyancy with eastward
   extent and the more elevated nature of the storms in time.
