CHICAGO (CBS) — You may be planning to enjoy some sizzling Chicago blues this weekend in Grant Park, but you ought to take precautions to make sure you’re not sizzling and singing the blues yourself.

CBS 2 Meteorologist Mary Kay Kleist reports the heat will be ratcheting up for the rest of the day Friday and on Saturday, and conditions will be steamy and sweltering come Sunday.

And while the winds over the water have kept conditions cooler by the lake for most of the past week, don’t look for that to happen this weekend. The wind is from the south-southwest, and the heat wave will affect everybody in the Chicago area.

In point of fact, as of 11:20 a.m. Friday, the lakefront was the warm spot at 83 degrees. It was 82 at O’Hare International Airport and 81 at Midway.

The ridge of high pressure that kept light and variable winds blowing over the lake has made its way off to the southeast. That steamy air from the Deep South is taking its place.

The forecast high for Friday is 85, with the upper 80s for the suburbs. Warm south winds will blow at 10 to 15 mph.

When the White Sox throw out their first pitch at 7:10 p.m. against the Houston Astros, look for a temperature of 80 degrees at U.S. Cellular Field. Sunset will come around at 8:26 p.m., and the overnight low drops to a comfortable 65.

On Saturday, the high climbs to 90, and on Sunday 92. And the humidity on Sunday will be thick and sticky, making for heat indices that will make it feel even hotter than it actually is.
The next rain chance is on Monday as a cool front comes in, but the chance is only 30 to 40 percent.

The high for Monday is 88, Tuesday 81, Wednesday down to 74, and Thursday 77.
