   Areas affected...the Middle TX Gulf Coast

   Concerning...Severe Thunderstorm Watch 713...

   Valid 250738Z - 250915Z

   The severe weather threat for Severe Thunderstorm Watch 713
   continues.

   SUMMARY...Increasing potential for severe gusts is apparent through
   the pre-dawn hours along the Middle Texas Gulf Coast.

   DISCUSSION...The deepest convection with the coldest IR cloud tops
   within WW 713 has been slowly moving eastward across Victoria/Goliad
   counties over the past hour. Upstream convection may coalesce with
   this leading slow-moving complex during the next hour or so. This
   would likely result in an accelerating cool pool towards the coast.
   Ahead of the cluster, surface dew points remain from 67-70 F and are
   yielding MLCAPE around 1500 J/kg per modified 00Z CRP sounding and
   06Z RAP forecast soundings. The 06Z HRRR is insistent on upscale
   growth with a potential bowing structure approaching the coast
   during the next few hours. While severe wind has yet to be reported
   thus far, the VCT ASOS recently measured 53 mph at 0729Z. The
   potential exists for gusts of 60-70 mph through 10-11Z.
