...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms may persist for few more hours this evening
across parts of central Florida and late tonight over portions of
coastal Washington, but organized severe thunderstorms are not
expected.

...Discussion...
A few storms remain this evening along and slightly north of the
cold front in central Florida. Weak to moderate instability remains
across this region and could support these storms for a few more
hours. However, as the boundary layer continues to cool, expect the
storms to weaken over land.

Some lightning is possible late tonight near the Washington coast as
cooling temperatures aloft result in weak instability over the
relatively warm waters off the Washington coast.
