The filming of the “Chicago Fire” television show that was scheduled for Thursday in Elmhurst was canceled after forecasts predicted thunderstorms throughout the day.

The roads that were supposed to be closed Thursday for filming are open, according to the City of Elmhurst. It is not clear if filming will be rescheduled.

The National Weather Service issued a hazardous weather outlook Thursday morning for DuPage, Cook and other counties, as rain and thunderstorms move though Illinois.

The greatest threat of severe thunderstorms Thursday is between 2 and 9 p.m., according to the National Weather Service, and thunderstorms may continue through the evening.

Some thunderstorms could produce:

• Locally heavy rainfall resulting in localized flooding
• Hail up to the size of half dollars
• Damaging winds up to 70 mph
• Frequent cloud-to-ground lightning
• Possibly an isolated tornado

The streets department performed a full sweep of Elmhurst city streets, checked low-lying areas and cleaned inlets in preparation for the storm, according to the city.
