If outdoors, consider seeking shelter inside a building. Torrential rainfall is also occurring with these storms and may lead to localized flooding. Do not drive your vehicle through flooded roadways.

Pockets of dense fog, locally reducing visibilities to under one half mile, will be possible through about 8 to 9 AM. The lowest visibilities will be in the vicinity of river valleys, including parts of the Kankakee, Illinois and Iroquois rivers. Motorists should be prepared for rapid changes in visibilities across short distances and allow extra following distance with the vehicle ahead of you.
