Strong to severe thunderstorms may produce damaging wind gusts up to 70 mph and hail up to 1.5 inches. Storms will move east across northern Illinois this afternoon, with additional development possible farther south.
Friday, July 3 discussion: A slow-moving frontal boundary will remain draped across the Midwest throughout the race weekend, bringing periodic opportunities for showers and thunderstorms to the Chicagoland area. While much of each day should remain dry, daytime heating, mid-level disturbances, and abundant humidity will support scattered thunderstorms with activity becoming more numerous during the afternoon and evening early hours.
Any storm that develops could produce frequent lightning, heavy downpours, gusty winds, and localized ponding of water. The exact timing and placement of thunderstorms will be difficult to predict, so teams and fans should remain alert for changing conditions. Outside of thunderstorms, expect warm, humid weather with light winds and no prolonged washout currently anticipated.

More about Chicagoland Speedway
Chicagoland Speedway is a 1.5-mile tri-oval located in Joliet, Illinois, that became a fixture on the NASCAR calendar after opening in 2001. The track features progressive banking in the turns, allowing multiple racing grooves to develop and encouraging side-by-side competition as drivers search for grip and clean air.
Known for its worn asphalt surface, Chicagoland often produces significant tire falloff, placing an emphasis on long-run speed and tire management. As rubber builds and laps accumulate, drivers are forced to move around the track, creating dynamic racing conditions and frequent lead changes.
The speedway gained a reputation for dramatic finishes and highly competitive racing, including several close battles in its later years on the schedule. Its combination of aging surface, variable lines, and strategic complexity made it a favorite among drivers and fans despite its recent absence from the NASCAR calendar.
