June 11 Midwest storms kept rattling U.S. travel on June 16

A June 11 severe-weather outbreak across northern Illinois and northwest Indiana grounded flights, knocked out power to hundreds of thousands of customers, and left travelers dealing with lingering schedule problems days later. National Weather Service Chicago said in a June 14 update that at least 17 tornadoes had been confirmed in its area of responsibility, with several rated strong to intense and additional damage surveys still underway.

The travel impact was immediate. AP reported ground stops at Chicago O’Hare, Midway, and New York’s JFK at various points on June 11 and 12, along with more than 1,000 delayed or canceled flights going into and out of Chicago. The same report said the storms also triggered outages across the Midwest and Northeast, while Commonwealth Edison expected most of its northern Illinois system to be restored by late Saturday.

Chicago reporting from the Sun-Times said O’Hare logged 844 cancellations between 9 p.m. Wednesday and 9 p.m. Thursday, while Midway had 39. It also said the South Shore Line briefly halted service and the White Sox postponed a game, underscoring how airport disruptions spilled into commutes and events around the region.

By Tuesday evening, June 16, the FAA listed O’Hare as on time. That was a recovery snapshot, not proof that every airline schedule was back to normal elsewhere. Airline alerts and airport-status pages remain the best same-day tools for passengers rerouted through a major hub like Chicago.
