   Areas affected...southwest Texas

   Concerning...Severe Thunderstorm Watch 99...

   Valid 102352Z - 110145Z

   The severe weather threat for Severe Thunderstorm Watch 99
   continues.

   SUMMARY...Storms capable of hail remain the primary severe concern
   this evening. Southwestern areas of the watch may be able to be
   cleared prior to watch expiration.

   DISCUSSION...A cluster of cells currently exist over northern
   portions of watch #99, with left splits gradually moving north
   across I-20. The cells are aided by long, straight hodographs, steep
   lapse rates, and sufficient moisture with an influx of 50s F
   dewpoints out of the southeast. 

   As peak heating passes, there is unlikely to be any additional
   forcing mechanism for additional storms, other than outflows of
   existing cells. Visible satellite imagery shows decreasing CU fields
   over southern and western parts of the watch over the past few
   hours. Otherwise, existing cells will likely last an hour or two
   longer prior to capping increasing this evening.
