   Concerning...Severe Thunderstorm Watch 315...

   The severe weather threat for Severe Thunderstorm Watch 315
   continues.

   SUMMARY...Cluster of severe thunderstorms should spread east this
   evening. New severe thunderstorm watch may be warranted.

   DISCUSSION...Scattered strong/severe thunderstorms have evolved over
   the TX Panhandle into northwestern OK within steep low-level lapse
   rate environment. Surface dew points are also holding just ahead of
   this activity despite surface temperatures in the mid-upper 90s.
   Satellite imagery suggests storm-top evacuation is beginning to
   increase over the northeast TX Panhandle, and if clustering
   continues there is a greater propensity for this activity to
   propagate downstream into western/northern OK. Additionally, LLJ is
   expected to strengthen across the southern Plains after sunset and
   this should contribute to forward propagation as well.
