CHICAGO (CBS) — Near-triple-digit heat is returning to the Chicago area yet again Monday, but a round of thunderstorms in the afternoon might help cool things off – at least a little.

CBS 2 Meteorologist Ed Curran pointed out what you’ll feel if you step outside – as of 11:20 a.m., it was already 91 degrees at O’Hare International Airport, 90 at the lakefront, and 93 at Midway Airport.

The southwest winds were bringing up the heat, but if there’s any good news, the dew points were only in the 60s – 64 at O’Hare and 66 at Midway – rather than in the 70s, which is enough to produce New Orleans-style humidity.

The heat index at 11:20 a.m. was 90 degrees at the lakefront, 95 at O’Hare, and 96 at Midway.

The high for the day was forecast at 99 degrees, which will tie a record for the day. The heat index might make it feel like 105.

But as the afternoon progresses, cloud cover will increase and isolated thunderstorms may pop up. Showers and storms were already seen in the Kankakee area before noon.

Overnight, the risk of showers and thunderstorms continues, including the possibility of a storm producing heavy rainfall in the afternoon. The overnight low drops to 74 degrees.

Beyond the storms, a cold front drops down, and the high for Tuesday is a comparatively comfortable 87. The high for Wednesday jumps to 91, Thursday back to 86, Friday 87, Saturday 86 again, and Sunday 84.
