CHICAGO (CBS) — Evening storms with threaten the area, with the highest chance just south of I-80. Storms in the area could include hail up to a quarter in size and wind gusts up to 60 mph.

The highest storm threat will be along that front, mainly for central Illinois.

Closer to Chicago there will be a chance for isolated showers and thunderstorms after dark, but those chances increase closer to 2 a.m.

The Thursday morning rush will probably have showers and thunderstorms around.
