Chicago, IL – A surge of powerful winds could sweep across northern Illinois and northwest Indiana late this week, potentially causing travel disruptions and isolated power outages from Thursday night into Friday.
Gusts may exceed 45 mph across the Chicago region, creating hazardous driving conditions on open highways and elevated roadways as the system strengthens overnight.
According to the National Weather Service in Chicago, the winds are not expected to be thunderstorm-driven but instead tied to a tightening pressure gradient behind a departing weather system. The strongest gusts are most likely late Thursday night through Friday afternoon.
Drivers along Interstate 90, Interstate 94, Interstate 80, and the Dan Ryan Expressway may notice sudden crosswinds, particularly high-profile vehicles such as trucks and buses. Communities from Rockford and DeKalb through Chicago, Joliet, and northwest Indiana could experience scattered tree damage if gusts approach the upper range.
Loose outdoor objects, trash bins, and temporary structures should be secured before the winds increase Thursday night. Commuters should allow extra travel time Friday morning as gusty winds may slow traffic across bridges and lakefront routes.
Conditions are expected to gradually calm Friday evening, though breezy weather could linger into the weekend.
