CHICAGO (CBS) — The summerlike weather Tuesday is giving way to storms.
A severe thunderstorm watch is in effect throughout the Chicago area until 11 p.m. A severe thunderstorm warning has also now been issued for Lake and McHenry counties until 7:45 p.m.
It was a super mild Tuesday with temps already running a good 20 degrees above average in spots.
But a cold front arrives Tuesday evening and with that comes a possible storm threat, according to CBS 2 meteorologist Mary Kay Kleist.
The cooler weather is expected anytime between 6:00 p.m. and 10:00 p.m. It’ll be felt southeast of Chicago into northwest Indiana.
Any storms that form could create large hail and damaging winds.
The highest storm coverage is southeast of Chicago into northern Indiana and southern lower Michigan into the Detroit metro area.
Much of northern Illinois can expect isolated storm chances as a layer of warm air aloft may limit storm formation.
