...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms remain possible along parts of the central
Gulf Coast tonight.

...01z Update...

Early-evening water-vapor imagery depicts a low-amplitude short-wave
trough progressing northeast along the middle TX Coast. This feature
will lose its identity as it ejects into the central Gulf States
later tonight. Scattered, shallow convection is noted ahead of this
feature from the northwestern Gulf basin, extending northeast along
the LA Coast into southern AL. Buoyancy is limited inland as surface
dew points are only in the lower 50s along the coast due to easterly
boundary-layer flow. Elevated instability should gradually increase
overnight and forecast soundings suggest ample buoyancy for
lightning discharge with updrafts rooted near 900mb. Isolated
thunderstorm potential continues.
