   Areas affected...the central Gulf Coast into parts of GA

   Concerning...Tornado Watch 354...

   Valid 182255Z - 190100Z

   The severe weather threat for Tornado Watch 354 continues.

   SUMMARY...Locally damaging wind and brief tornadoes will remain
   possible into this evening.

   DISCUSSION...An extensive QLCS is ongoing as of 2255 UTC from
   western GA into southern AL. Rather strong low/midlevel flow remains
   in place along/ahead of this QLCS, in association with a midlevel
   shortwave trough and the remnants of TC Arthur. 0-1 km SRH of
   150-250 m2/s2 within the moist/tropical environment will continue to
   support brief-tornado potential, especially where the line has taken
   a more north-south orientation across western GA.  There is some
   evidence of a moderately strong westerly rear-inflow jet from the
   KEOX VWP, which will support damaging-wind potential along that
   portion of the QLCS as it moves eastward across southwest GA and
   southeast AL.

   Substantial convection persists farther southwest into southern MS
   and southwest AL. Some enhancement to low-level shear/SRH persists
   in this area, which could support a wind-damage and brief-tornado
   threat in this region as well. However, the QLCS has taken on a less
   favorable east-west orientation in this area, which may tend to
   limit a more organized severe threat. Trends will continue to be
   monitored in this area for an uptick in storm intensity and
   organization this evening.
