...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A few thunderstorms are expected near/along the northern Gulf Coast
tonight.

...01z Update...

Low-amplitude short-wave trough is advancing east-northeast across
the lower MS Valley early this evening. A corridor of weak
convection is noted ahead of this feature from southeast LA into
southwest AL. The deepest, more robust updrafts over southeast LA
are generating a few flashes of lightning. Surface-based buoyancy is
not expected to materialize inland through sunrise, and any
thunderstorm activity near the Gulf Coast will be driven in large
part by warm advection, and should remain elevated. Midlevel
instability appears too weak to warrant any meaningful risk for
severe.
