Valid 081200Z - 091200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Very isolated thunderstorms will be possible Wednesday night across
parts of west Texas.

...West Texas...

A closed mid/upper low will migrate slowly across northwest Mexico
on Wednesday. Deep-layer southwesterly flow ahead of this feature
will result in a warm advection regime atop a sub-freezing
boundary-layer across portions of Texas Wednesday night into early
Thursday. Meager elevated instability may develop within the 750-500
mb layer amid increasing moisture, cold temperatures aloft, and
steepening midlevel lapse rates. This may be sufficient for a few
lightning flashes after midnight local time.
