...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated to scattered thunderstorms are possible on Thursday across
coastal portions of the western and central Gulf Coast vicinity.
Severe potential appears low at this time.

...Western and Center Gulf Coast vicinity...

Broad upper troughing will envelop much of the CONUS on Thursday.
Strong surface high pressure will be in place over the Rockies/Great
Basin, as well as across the Midwest. Meanwhile, a cold front will
be draped along/just offshore the TX coast, while a warm front
extends eastward near the LA coast, then southeast across the
eastern Gulf.

As an upper shortwave trough moves across the Plains, a weak coastal
low will develop along the Upper TX Coast/LA coast late in the
period. This may allow richer Gulf moisture to move into far
southeast LA and coastal MS/AL in the 09-12z time period. Midlevel
warm advection and increasing ascent atop a cool boundary layer will
support elevated thunderstorm activity along portions of the
western/central Gulf coast through the period. While some
surface-based instability could move inland very late in the period,
this is uncertain and may remain over immediate coastal areas of
southeast LA. Overall, severe potential is expected to remain
limited given Gulf moisture will mostly remain offshore through the
period, though trends will be monitored for some increasing
potential late in the Day 3 (early Friday morning) time frame.
