Temperatures are expected to start dropping heading into the evening hours Wednesday, the lows falling into the mid-30s inland and mid-40s along the lakefront.

The drop is forecast to happen quickly, with the first widespread frost of the season likely in parts of north central Ilinois late in the evening.

The frost risk continues into Thursday, with counties including Winnebago, Boone and Ogle under a frost advisory from 2-9 a.m.

Scattered thunderstorms were expected across parts of the Chicago area, some of which could produce strong winds.

Thursday is expected to stay most sunny and cool, with highs only reaching into the low- to mid-50s.

The week ends on a mostly sunny and cool note, though temps will start to rebound with afternoon highs in the low-60s Friday.

The weekend is expected to stay in the low-70s with a chance for showers and thunderstorms.
