   Areas affected...portions of far eastern Texas into central
   Louisiana and western Mississippi

   Concerning...Severe Thunderstorm Watch 225...

   Valid 100300Z - 100430Z

   The severe weather threat for Severe Thunderstorm Watch 225
   continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 225. Severe wind and hail should be the main threats over the
   next few hours. However, upscale growth into one or more MCSs is
   possible tonight, with severe winds becoming the primary threat.

   DISCUSSION...Multiple semi-discrete supercells and multicellular
   clusters persist across eastern TX into central MS amid a very
   unstable and highly sheared troposphere. As such, any storms that
   remain discrete will have the potential to continue producing severe
   hail in addition to damaging gusts. There is also some potential for
   upscale growth into one or more progressive, cold-pool-driven MCSs,
   as indicated by the 01Z run of both the HRRR and Warn-on-Forecast
   ensemble. Should this occur, focused corridors of severe winds could
   accompany these MCSs. At the moment, the best potential for upscale
   growth appear to be with the convective clusters in far eastern TX
   and perhaps with rapidly intensifying storms in north-central LA.
