Over 400 flights have been canceled Thursday at O'Hare and Midway international airports as potentially severe thunderstorms and high winds threatened the Chicago area.
As of 6 p.m., over 400 flights at O'Hare had been canceled, and 23 were canceled at Midway, according to the Chicago Department of Aviation.
Strong thunderstorms rolled through the area on Thursday afternoon, packing high winds and heavy rains. Areas south of Chicago received some hail, and a tornado warning was issued in northwest Indiana as the system moved through the area.
A Wind Advisory took effect for most of northern Illinois and northwest Indiana beginning at 10 a.m. DeKalb, Kane, DuPage, Cook, LaSalle, Kendall, Grundy, Will, McHenry and Kankakee counties are all under the advisory in Illinois, as are Lake, Porter, Newton, Jasper, and Benton in northwest Indiana.
The advisory will remain in effect through Thursday evening, according to the National Weather Service. Wind speeds in excess of 50 mph are expected in the southern part of the advisory area, including Kankakee, Will, and Grundy counties, and wind gusts between 45 and 50 mph are expected elsewhere in the advisory area.
In the late evening hours on Thursday, temperatures will begin to drop as the low pressure system continues its push, transitioning any lingering rain to snow showers. By the time Friday rolls around, high temperatures likely won’t reach 40 degrees, as unseasonably cool weather takes hold for several days.
Over the weekend, sunny skies Saturday will give away to potential drizzle or light snow on Sunday, and temperatures will remain in the high-30s or low-40s over the two days.
