CHICAGO (CBS) -- Temperatures at Midway International Airport on Tuesday reached 100°, the first time Midway has seen triple-digit temperatures since July of 2012. 

With the humidity factored in, it felt like 106° at Midway this afternoon.

The city's official temperature records are measured at O'Hare, so it's not an official record for this date in Chicago, which was 99°, set in 1987. 

O'Hare saw temperatures hit 96° by 3 p.m., with a heat index of 103°.

The normal high temperature for June 14 is 80°, which will be the approximate low temperature overnight.

Those sweltering temperatures have virtually all of the Chicago area under an excessive heat warning until 8 p.m. Wednesday, except in Lake and McHenry counties, which are under a heat advisory.

The intense heat comes as cleanup efforts continue in the wake of Monday's storm, which brought a lot of straight-line wind damage. The National Weather Service is also continuing to study the damage to determine if there is evidence of a brief tornado or two. 

Wind gusts reached 84 mph at O'Hare on Monday.

Wednesday's high will reach around 97°, with feels-like temperatures a little over 100°. 

Storms at night on Wednesday. 

Thursday will be just over 90°.

Relief comes Friday, Saturday and Sunday, with cooler conditions. 

Temperaturess are back in the 90s by Monday.

Tonight- Clear, warm and muggy. Low of 81.

Wednesday- Sunny, hot and humid. High of 97. Feels-like temp around 100. 

Wednesday Night- T-storms.

Thursday- 91 for a high.
