   Areas affected...Parts of central into southeast Texas

   Concerning...Severe Thunderstorm Watch 352...

   Valid 012037Z - 012200Z

   The severe weather threat for Severe Thunderstorm Watch 352
   continues.

   SUMMARY...The risk of large hail and severe wind gusts continues
   across Severe Thunderstorm Watch 352.

   DISCUSSION...A couple semi-discrete supercells continue to track
   southeastward along the stationary boundary from central into
   southeast TX -- along the east/southeastern periphery of around 2500
   J/kg MLCAPE. While these storms are generally becoming removed from
   this stronger instability, they will still pose a risk of isolated
   large hail and locally severe gusts in the near term. To their
   northwest, fresh updrafts are evolving along the stationary boundary
   near Waco TX. Given that these evolving storms will track
   southeastward through the strongest instability amid 40 kt of
   effective shear, gradual intensification into semi-discrete
   supercells is also possible -- posing a risk of large to very large
   hail and severe wind gusts.
