CHICAGO (CBS) — Conditions will be undeniably beautiful for the rest of the day Thursday, but break out the gym shorts and Gatorade this weekend, as steamy heat settles in.

As of 11:20 a.m., it was a comfortable 76 at O’Hare International Airport, 75 at Midway Airport, and 69 at the lakefront. A low-pressure system is hovering over downstate Illinois, and keeping conditions sunny and dry with an east wind of only 3 mph.

With the calmer wind, the lakeside cooling will be lesser compared with earlier in the week.

The high for the day is forecast at 71 in Kenosha, Wis., 72 in Waukegan, 76 in Gary, Ind., 80 in Crystal Lake, 82 in Naperville, and 85 in Peru and Morris. The official forecast high at O’Hare is 80, with the low dropping to 58 overnight.

The high pressure system moves to the mid-Atlantic states on Friday, making way for a mass of hazy, hot and humid air from the Deep South.

The temperature begins picking up on Friday, when a high of 85 is expected. The high for Saturday is 89 and Sunday 91, although suburban areas west of Chicago will likely see the 90s both days.

The high for Monday is 87, Tuesday 80, and Wednesday 79. While we need rain, the next chance of any coming is Monday, reports CBS 2 Meteorologist Mary Kay Kleist.
