Temperatures cool down overnight in Chicago

CHICAGO (CBS) — A cold front will cross the Chicago area, and a cooler wind flow will develop overnight.

After a steamy day with highs well into the 80s, Sunday will feature many hours in the 60s — topping off in the lower 70s away from the lake.

The northerly wind tonight and Sunday will generate high wave action and dangerous rip currents. Active waves crashing onshore will flood some of the lakefront path.

A Beach Hazard statement will be in effect tonight through Sunday. A Small Craft Advisory will also be in place.
