...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms remain possible across the Midwest and Ohio
Valley this evening. Severe thunderstorm threat is low.

...01z Update...

Low-amplitude short-wave trough is ejecting across the Ohio Valley.
Large-scale forcing ahead of this feature is primarily responsible
for scattered convection that currently extends from western PA,
arcing southwest along the Ohio River into southeast MO. While much
of this activity is not producing lightning, isolated thunderstorms
are noted along a corridor of somewhat stronger instability that
extends into central OH. However, 00z sounding from ILN does not
exhibit appreciable buoyancy, though lapse rates are fairly steep
and moist. Deepest updrafts will continue to produce lightning for
the next few hours, but overall thunderstorms should remain mostly
isolated.
