   Areas affected...far southeast TX into southwest LA

   Concerning...Severe Thunderstorm Watch 162...

   Valid 290911Z - 291045Z

   The severe weather threat for Severe Thunderstorm Watch 162

   SUMMARY...The damaging wind risk will increase across far southeast
   Texas into southwest Louisiana over the next 1-2 hours. A tornado
   also may be possible with this activity.

   DISCUSSION...Some increase in intensity has been noted in radar
   imagery over southeast TX into southwest LA in the last 30 minutes
   or so. Reflectivity cores have deepened/intensified on 7 km CAPPI
   and some increase in velocity signatures are also noted. Convection
   will continue to move into an uncapped airmass close to the coast
   characterized by SBCAPE around 1500 J/kg. Furthermore, increasing
   low-level rotation has been noted in cells over southeast TX ahead
   of the convective line. Tornado potential may be somewhat increased
   as these more cellular elements merge with the line in the near
   term. HGX and LCH VWP data show favorable low-level hodographs
   supporting rotation and a brief tornado or two may occur in addition
   to damaging gusts associated with the southeastward surging bow into
   southwest LA.
