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.
