The Federal Aviation Administration imposed temporary ground stops at Chicago's two major airports on Sunday, August 9, 2026, as severe weather moved through the region. O'Hare International Airport saw a halt to departures just before noon, while Midway Airport received a similar order shortly before 1 p.m.
The FAA lifted the O'Hare ground stop just after 3 p.m., allowing flights to resume after more than three hours of suspension. Despite the clearance, the airport continued to experience significant backlog, with an average delay of about 100 minutes reported for departing flights after the lift. Midway's ground stop remained in effect beyond the O'Hare clearance, extending the period of disruption for travelers using that facility.
The weather conditions prompting the stops included heavy precipitation and strong winds that affected the Chicago area throughout the afternoon. The FAA's decision to halt departures was a safety measure intended to keep aircraft on the ground while crews assessed the impact of the storms on runway and air traffic control operations. Once conditions improved sufficiently at O'Hare, the agency authorized the resumption of departures, though the lingering effects of the earlier stoppage kept delay times elevated.
Airlines and passengers at both airports faced extended wait times as the weather system moved through the region. The coordinated ground stops at O'Hare and Midway reflected the FAA's standard protocol for managing severe weather impacts on air travel, prioritizing safety while attempting to minimize overall disruption.
Travelers were advised to monitor flight status updates and remain prepared for further schedule changes as the storm continued to affect the area. The FAA's actions underscore the challenges that severe weather poses to the nation's busiest air travel hubs, especially when multiple airports are simultaneously impacted.
