Meteorologists Phil Schwarz and Cheryl Scott said strong storms could produce large hail and damaging winds. There is a low tornado threat, and flooding is possible.

Several rounds of scattered, strong storms began hitting the Chicago area after 10 p.m. Monday.

Areas north of the city are at highest risk for severe storms.

More storms are possible overnight and into early Tuesday before the area gets a break in activity.

Dry and warm conditions are expected for most of Tuesday before the second round of strong storms arrives after 4 p.m.

The main threat will shift south of the city on Tuesday night, with storms continuing through midnight.

This comes as temperatures reached 80 degrees on Monday afternoon, breaking the daily record of 79 degrees set back in 1998. It will also be the warmest day of the year so far.

But temperatures will fall sharply late Tuesday as the front moves in.

Looking ahead, temperatures Wednesday will be about 30 degrees colder than Tuesday. More rain and storms are expected on Thursday and again on Saturday.
