The Chicago National Weather Service Forecast Office has issued a Frost Advisory from 4AM CDT to 8AM CDT Thursday morning covering the areas away from the City of Chicago (blue-shaded counties on the headlined map). Temperatures are expected to drop into the lower and middle 30s creating a widespread frost, killing sensitive uncovered plants. A Frost Advisory also extends into northwest Indiana as well as north into southeastern Wisconsin and south into east-central Illinois.

However clouds spreading south out of Wisconsin are expected to inhibit  a much further drop-off of temperatures.
