...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL GULF COAST...

...SUMMARY...
Thunderstorms with isolated severe wind gusts will be possible this
evening into tonight along the central Gulf Coast.

...Discussion...
Thunderstorm activity will continue across portions of the central
Gulf Coast this evening. While the more favorably unstable air mass
remains mostly offshore, occasional strong cells/clusters may track
inland with potential for damaging winds as large scale ascent
increasing through the evening/overnight period. Closer to the front
offshore, a few transient supercells and a tornado may be possible.
Overall, the threat inland remains isolated and a Marginal risk was
maintained this evening to account for this potential.
