Tinley Park at 'Slight Risk' of Severe Weather Throughout Tuesday

Serious storms may be headed our way, warns the National Weather Service. 

The storm system that dropped large hail and tornadoes on parts of Iowa, Kansas and Oklahoma is now headed toward Illinois. The National Weather Service has placed most of Illinois—including Will and Cook County—in the "slight risk" category for severe weather on Monday and Tuesday. 

The main threats on both days consist of damaging winds and large hail. The National Weather Service's Storm Prediction Center noted in its technical discussions that isolated tornadoes are also possible on Monday and Tuesday.

"The most violent storms will ignite during the afternoon and evening hours as daytime heating causes instability," Accuweather.com Meteorologist Meghan Evans wrote in her forecast. "Plenty of humid air will be in place to fuel the severe storms."

Thunderstorms continue into Wednesday with temperatures in the low- to mid-60s, dropping significantly for Thursday and throughout the weekend.
