...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
General thunderstorms are possible Sunday from southern Texas into
southern Louisiana. Severe weather is unlikely.

...Synopsis...
A shortwave trough with cyclonically curved speed max will move east
across TX and toward the lower MS Valley on Sunday, providing strong
winds aloft and large-scale lift. Ahead of this trough,
east/northeast surface winds will maintain a cool/stable air mass
with high pressure, preventing any appreciable destabilization along
the Gulf Coast. Models clearly show the surface low remaining over
the Gulf of Mexico, with little if any SBCAPE over land. Despite
this, southerly winds and moisture advection above the surface will
likely result in weak elevated instability, supporting at least
isolated elevated thunderstorms across much of southern and eastern
TX and perhaps southern LA.
