   Areas affected...central TX

   Concerning...Severe potential...Watch unlikely 

   Valid 280837Z - 281000Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Strong gusts and hail are possible with a cluster of
   strong storms moving east over the central TX.

   DISCUSSION...A cluster of storms has intensified to the west of the
   I-35 corridor/greater San Antonio area early this morning. This
   activity is occurring within a moderately unstable airmass amid 40
   kt effective shear magnitudes. Radar trends have shows some
   indication of strong outflow gusts associated with this cluster,
   though KERV only gusted to around 27kt as the core of these stronger
   velocity signatures passed just south of the observation site.
   Nevertheless, some strong gusts and perhaps hail will be possible as
   the cluster approached the I-35 corridor over the next hour or so.
   Given a lack of stronger forcing, and the absence of a low-level
   jet, it is unclear how long this cluster may maintain its current
   intensity. Overall, severe potential should remain limited and a
   watch is not expected.
