   Areas affected...Central/Southern LA...Far Southeast TX

   Concerning...Tornado Watch 100...

   Valid 251024Z - 251130Z

   The severe weather threat for Tornado Watch 100 continues.

   SUMMARY...Threat for damaging wind gusts and a tornado or two
   continues across far southeast TX and central/southern LA. This
   threat will likely extend past 11Z and a local watch extension may
   be needed.

   DISCUSSION...Multicellular storms along and just ahead of an
   eastward moving cold front have gradually intensified over the past
   hour with several now exhibiting supercellular characteristics. 06Z
   LCH sounding sampled a very moist and moderately unstable airmass
   amidst strong deep-layer shear. Wind speeds aloft have increased
   since that time, with the KPOE VAD wind profile now showing winds
   over 60 kt at 5kft. This favorable environment will likely lead to
   the persistence of the ongoing storms, with at least some potential
   for the development into another convective line like the one
   farther north in central MS (discussed in MCD 441). Given that the
   threat will likely extend pass the watch expiration time of 11Z, a
   local extension in time and perhaps area may be required.
