Areas affected...Southern Mississippi into southwest Alabama

Concerning...Severe Thunderstorm Watch 44...

Valid 080239Z - 080445Z

The severe weather threat for Severe Thunderstorm Watch 44
continues.

SUMMARY...A dying line of storms will progress east across
Mississippi and perhaps into southwest Alabama this evening. While a
few strong wind gusts are possible, a watch is not required.

DISCUSSION...A long-lived MCS continues to weaken this evening, with
a decrease in trailing STRATIFORM precipitation and a thinning of
the leading-edge convection.

00Z soundings into central MS and AL indicate that diurnal cooling
of the boundary layer will likely lead to a decrease in storm
coverage, both ahead of the line and within, as a capping inversion
exists around 700 mb. Instability levels are much weaker into the FL
Panhandle region, with nearly zero MLCAPE noted on the TLH sounding.
Thus, trends of the last hour are expected to persist.
