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.
