   Concerning...Severe Thunderstorm Watch 129...

   The severe weather threat for Severe Thunderstorm Watch 129
   continues.

   SUMMARY...The severe weather threat for weather watch 129 continues.
   Strong winds and large hail are the main threats through this
   evening.

   DISCUSSION...Scattered thunderstorms have developed across the Texas
   and Oklahoma Panhandles late this afternoon underneath a shortwave
   trough. Mesoanalysis indicates the storms are ongoing in an
   environment characterized by MLCAPE of 500-1000 J/kg and 50-60 kt of
   effective bulk shear. While still high based due to surface 
   temperature dewpoint spreads of 25-30 F, these storms should
   continue to pose a threat for strong damaging wind gusts and large
   hail. Hi-res forecast guidance shows storms will continue to develop
   and move east southeast along the warm front corridor into western
   Oklahoma where the environment remains favorable for severe weather.
   A conditional, more isolated threat exists along the dryline where
   cumulus have become more agitated over the last hour. Some hi-res
   members show storm development in this corridor where surface
   moisture and instability are higher.
