...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorm potential appears negligible tonight.

...Discussion...
With the surface cold front having recently pushed off the FL
Peninsula/Keys, dry/stable conditions will mitigate
lightning-producing convection across the CONUS tonight. Isolated
thunderstorms are possible offshore across the FL Straits as the
boundary slows/stalls.
