...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are possible across portions of the Midwest, the Upper
Midwest, and the northern High Plains, though severe storms are not
expected.

...Synopsis and Discussion...
A midlevel trough will amplify as it advances southeastward from the
northern Plains into the Midwest on Wednesday, while a surface low
will develop over Missouri and moves into the Lower Ohio Valley. A
cold front will extend southwestward from this surface low with a
warm front to the northeast. 

Despite limited boundary-layer moisture, steep midlevel lapse rates
will yield sufficient instability (albeit weak) for isolated
thunderstorms along the warm front during the evening/overnight
hours. Some thunderstorms may develop along the cold front where
slightly greater instability is forecast. Locally strong gusts
cannot be ruled out, but the weak instability should limit storm
intensity. 

Isolated thunderstorms are expected across the northern Plains and
Upper Midwest as a mid-level trough amplifies and moves south and a
mid-level jet streak overspreads the region.
