...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not forecast through tonight.

...Discussion...
A fast moving surface low, associated with a strong mid-level jet
streak, will continue to move east-southeastward toward the western
Great Lakes this evening. Forecast soundings show some very weak
elevated instability within the warm sector, but it does not appear
instability will be deep enough for sufficient charge separation for
any thunderstorm activity. Elsewhere in the CONUS, thunderstorm
activity will be minimal without significant instability in place.
Some lightning has occurred south of the Florida Keys, in the
vicinity of the stalled surface front. However, the lightning
activity has remained well offshore and is expected to remain so.
