...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Threat for lightning is limited tonight.

...01z Update...

Notable mid-level short-wave trough is digging southeast across the
OH Valley early this evening. Seasonally cool, lower/mid-
tropospheric profiles are resulting in steep lapse rates in the
lowest 3-4km across much of the Great Lakes. While this is proving
favorable for lake convection, lightning within the deeper, most
robust updrafts has been limited. While a few strikes can not be
ruled out with this activity, the probability for thunderstorms is
less than 10% tonight, and for this reason probabilities have been
lowered.
