A tornado watch that was initiated Thursday in counties across central and northern Illinois has expired, according to the National Weather Service.
The watch was set to be in effect until 5 p.m., but expired by 2:45 p.m. Thursday.
The following counties were affected:
Boone, Champaign, Cook, DeKalb, DeWitt, DuPage, Ford, Grundy, Iroquois, Kane, Kankakee, Kendall, Lake, LaSalle, Livingston, McHenry, McLean, Piatt, Vermilion and Will.
The service issued a hazardous weather outlook just before 12:30 p.m. Wednesday, warning of an elevated risk of quarter-size hail, winds up to 60 mph and tornadoes.
Scattered severe thunderstorms are expected ahead a strong cold front.
"There is a risk for tornadoes, damaging winds and hail with the most intense thunderstorms, with the higher threat over the Chicago metro along and east of Interstate 55," the warning said.
