   Areas affected...Central and Southeast Texas

   Concerning...Severe Thunderstorm Watch 166...

   Valid 242228Z - 250030Z

   The severe weather threat for Severe Thunderstorm Watch 166
   continues.

   SUMMARY...The threat for damaging straight line winds continues
   across WW 166 in portions of central and southeastern Texas. Trends
   will continue to be monitored for whether or not local watch
   extensions or re-issuance may be needed later this evening.

   DISCUSSION...A linear bowing convective complex is ongoing across
   east-central Texas, currently moving east-southeast towards the
   Louisiana border and the Gulf Coast. While surface observations from
   behind the convective outflow have generally remained below severe
   criteria, MLCAPE of 15000-2000 and 40 kts of deep-layer shear will
   continue to support storm organization and longevity into this
   evening. As the convective complex reaches the edge of WW 166, local
   watch extensions southeastward may be necessary. New WW issuance
   could be needed if the bowing segment continues to maintain its
   intensity into the evening, but this scenario remains uncertain at
   this time.
