Chicago Weather: Near Record Heat Midweek

CHICAGO (CBS) -- We hit 97 degrees on Monday, making it the hottest day of the year.

A record was not set though. The record for this date is 100 degrees set in 1947.

There is an isolated storm chance at daybreak, especially near the Wisconsin line. Most storm activity stays over Wisconsin and Michigan.

It will be back to the 90s on Tuesday afternoon. But a small lake breeze may keep shoreline temps slightly cooler.

As a hot southwesterly wind flow takes shape midweek, as temps soar to record levels. The record high for both Wednesday and Thursday is 97 degrees, both set in 1973.

A cold front arrives Thursday night into Friday with rain chances and seasonable temps for the weekend.
