Day 1 Convective Outlook

Valid 130100Z - 131200Z



...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.
