...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through tonight.

...01Z Update...
During the 08-12Z time frame, a subtle midlevel impulse (evident in
water-vapor imagery) will advance east-northeastward from MX to
South TX. In response, weak low-level warm advection and moistening
atop a cool/stable boundary layer may support a couple elevated
thunderstorms along the Middle TX Coast and vicinity.
