Areas affected...Middle TX Coastal Plain

Concerning...Severe Thunderstorm Watch 57...

Valid 211408Z - 211545Z

The severe weather threat for Severe Thunderstorm Watch 57
continues.

SUMMARY...Thunderstorms capable of hail remain possible over the
Middle Texas Coastal Plain for the next few hours.

DISCUSSION...Elevated thunderstorms have persisted for the past few
hours over the Middle TX Coast amid continued warm-air advection and
modest buoyancy. Vertical shear is strong enough for rotating
updrafts, and a few stronger, more organized updrafts have been
noted embedded within the larger precipitation field. The best
environment is currently just offshore, as evidenced by the
supercell ongoing offshore about 40 miles south of Palacios. Even
so, potential still exists for a few updrafts strong enough to
produce hail over the next few hours.
