   Areas affected...East Texas...North-central Louisiana...Western and
   Central Mississippi

   Concerning...Severe Thunderstorm Watch 387...

   Valid 040223Z - 040430Z

   The severe weather threat for Severe Thunderstorm Watch 387
   continues.

   SUMMARY...An isolated wind-damage threat will be possible as a
   linear MCS moves into the central Gulf Coast states during the
   overnight period. The ongoing severe thunderstorm watch has been
   extended in area into south-central Mississippi, and may also need
   to be extended in time over parts of far eastern Texas and far
   western Louisiana.

   DISCUSSION...Mosaic radar imagery over the lower Ohio and Sabine
   River Valleys shows two organized line segments. The first is a
   larger-scale line associated with an MCS that is moving into western
   Mississippi. The second is a relatively small-scale bowing line
   segment over northeast Texas. These two features are located within
   a moderately unstable airmass, with the RAP analyzing MLCAPE in the
   2000 to 3000 J/kg range. In addition, the WSR-88D VWP at Fort Polk,
   LA and 00Z sounding at Jackson, MS have 0-6 km shear near 35 knots,
   and gradually veering winds with height in the lowest 3 km. This
   wind profile will be continue to be favorable for linear
   organization, associated with an isolated wind-damage threat late
   this evening into the overnight period. The threat should be
   greatest from eastern Louisiana and western Mississippi, although a
   secondary threat area will exist near the Sabine River in western
   Louisiana.
