Potentially severe thunderstorms could pass through the area as afternoon temperatures are expected to near 100 degrees, weather officials said.
An upper atmospheric disturbance heading toward southern Wisconsin and northern Illinois could bring storms to the area this morning or by the early afternoon, according to the National Weather Service.
If the disturbance does produce showers, there is a "fairly high probability" that they will become severe, generating damaging winds and flash flooding conditions, according to the weather service's Romeoville office.
Despite the storms, temperatures are expected to reach the 90s by noon, with a high temperature near 100 degrees, according to WGN-TV's meteorologist Tom Skilling.
