...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible in the vicinity of the Lower
Texas Coast later tonight.

...01z Update...

Low-amplitude short-wave trough is embedded within the southern
stream over deep South TX. This feature is shearing east toward the
northwestern Gulf basin where it is expected to encourage isolated
thunderstorm development, primarily off the south TX Coast later
tonight. 00z sounding from BRO was notably capped with strong
inhibition around 2km. Latest model guidance suggests inhibition
will gradually weaken which may allow isolated offshore convection
to gradually approach the coast later tonight. Even so, this
activity should remain weak with the greater concentration holding
offshore.
