   Concerning...Severe Thunderstorm Watch 156...

   Valid 291005Z - 291200Z

   The severe weather threat for Severe Thunderstorm Watch 156
   continues.

   SUMMARY...A wind damage and hail threat will likely continue over
   the next few hours across parts of the Texas Hill Country and Texas
   Coastal Plains.

   DISCUSSION...A squall line continues to move southward across the
   Texas Hill Country extending eastward to near the Gulf Coast in the
   Beaumont/Port Arthur area. South of the line of storms, the airmass
   is strongly unstable with MLCAPE estimated in the 3000 to 4000 J/kg
   range by the RAP. The line is being supported by a shortwave trough
   diving southeastward through the central and southern Plains evident
   on water vapor imagery. In addition, southwesterly low-level flow of
   30 to 40 kt is feeding into the linear MCS helping to sustain strong
   updrafts. The squall line has been producing 60 to 70 mph wind gusts
   over the last hours and is expected to remain severe for a little
   while longer. As the line continues to move southward to the middle
   and upper Texas Coast, wind damage will be possible along the
   leading edge of the squall line. Hail may also occur with the
   stronger cells embedded in the line.
