The severe weather has caused significant disruptions, including flight delays and cancellations at Chicago O'Hare International Airport, where delays averaged 90 minutes. Flash flooding has been reported in northwest Indiana, and slick roads contributed to accidents, such as a car entering a retention pond in Mundelein. Emergency crews responded to incidents caused by the storms, and heavy rain led to delays at Rate Field during a White Sox game. Residents in affected areas should remain vigilant as additional storms could bring gusty winds, hail, and further flooding risks.
