   Areas affected...northeast Louisiana into much of central
   Mississippi

   Concerning...Severe Thunderstorm Watch 80...

   Valid 092314Z - 100215Z

   The severe weather threat for Severe Thunderstorm Watch 80
   continues.

   SUMMARY...The threat for damaging straight-line winds may increase
   over the next few hours, from northeast Louisiana into central
   Mississippi.

   DISCUSSION...A broken line of storms extends from near the AR/MS
   border into northeast LA. The most intense of these storms was over
   northeast LA, with an east/northeast effective motion.

   The air mass ahead of these storms is very unstable, with MLCAPE
   over 3000 J/kg. Wind speeds in the lower levels are not particularly
   strong, but veering from the surface to 3 km will support updraft
   propagation.

   Recent radar trends show new cells developing south of the more
   organized LA/AR structures, near the outflow boundary. With time,
   upscale growth and organization of this cluster may occur as the
   system propagates into MS. Damaging winds will be the primary risk,
   though sporadic large hail is expected as well due to ample
   instability and steep lapse rates aloft.
