...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected, but isolated thunderstorms
may occur near the Gulf Coast tonight.

...Middle Gulf Coast...
Longwave troughing and prevalent cyclonic upper flow will persist
over the CONUS with cold/stable conditions remaining prevalent from
the Rockies eastward. Weak cyclogenesis is expected to occur over
the western to northern Gulf of Mexico tonight, with increasing
warm/moist advection toward the middle Gulf Coast. Richer low-level
theta-e will approach areas such as coastal southeast Louisiana late
tonight, although the potential for inland surface-rooted
destabilization should remain limited, with thunderstorms tending to
focus offshore.
