...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for severe thunderstorms is low across the U.S. through
tonight.

...Gulf Coast...
A highly amplified large-scale pattern will persist through tonight,
including a slow eastward evolution of a currently closed trough
over the Ozarks toward the Mid-South through tonight. In association
with richer moisture, scattered thunderstorms are expected to be
most common over the open Gulf of Mexico waters off of
Louisiana/Mississippi/Alabama and eventually off the Florida
Panhandle tonight, but a few thunderstorms will also be possible
over inland areas of the region this afternoon and tonight in
vicinity of a northward-extending surface trough. Organized severe
storms are unlikely. While a stronger storm or two could conceivably
occur near coastal Louisiana (Plaquemines Parish) or near coastal
parts of Mississippi/Alabama this evening into the overnight, latest
thinking continues to be that inland destabilization will be limited
and that the stronger/more organized storms will likely remain
offshore through late tonight.
