Chicago Weather: Cooler And Less Humid

CHICAGO (CBS) -- Look for partly cloudy skies Thursday night with upper 60s.

High waves on the lake continue to make for dangerous swimming conditions – the waves will crest at 4 to 7 feet. The risk is in place through Friday evening.

Friday and Saturday will see quiet weather with partly sunny conditions and temperatures in the lower 80s.

Sunday involves an increasing chance of showers and storms as we move into the afternoon.
