Areas affected...northeast Louisiana...central and southern
Mississippi...and southwest Alabama

Concerning...Severe Thunderstorm Watch 181...

Valid 292002Z - 292200Z

The severe weather threat for Severe Thunderstorm Watch 181
continues.

SUMMARY...The potential for more widespread wind damage is expected
to increase across portions of central and southern Mississippi into
southwest Alabama over the next 2-3 hours.

DISCUSSION...A west-to-east-oriented band of strong to severe storms
is ongoing just south of the I-20 corridor in MS and northeast LA as
of 20z. Occurrences of hail to 1" and thunderstorm wind damage have
been reported in the Jackson, MS vicinity within the past hour.
Additional elevated storms ongoing to the west of the watch area
across northern LA are expected to merge with the predominant band
of storms over the next hour, which should enhance overall cold pool
strength. That process may lead to an accelerated southeastward
motion of the convective band from central into southern MS and
southwest AL with an attendant risk for more widespread damaging
winds.

Isolated occurrences of large hail will remain possible, especially
on the western flank of the convective system where mid-level lapse
rates are steeper.
