....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms may be noted early this evening.

....01z Update...

Low-amplitude short-wave trough is ejecting across the Great
Lakes/Ohio Valley region early this evening. Primary corridor for
large-scale ascent is now focusing across the upper OH Valley into
the northern Middle Atlantic, as LLJ strengthens ahead of the short
wave. Widespread precipitation is noted within the warm advection
zone but elevated convection is gradually weakening, and only a few
flashes of lightning may be noted for the next few hours along the
nose of the LLJ.  Additionally, shallow weak convection is currently
observed along the trailing cold front across KY into TN, but this
activity has struggled to attain heights necessary for lightning.
This activity will likely remain too shallow the rest of tonight for
any meaningful risk for thunderstorms. 01z adjustments will reflect
lower confidence in lightning, thus severe probabilities will be
removed.
