Damaging storms are sweeping through the Midwest, disrupting flights at Chicago airports and knocking out power to hundreds of thousands of customers. The National Weather Service issued tornado warnings Wednesday across Illinois, Kansas, northern Missouri, and southern Iowa. There were also severe thunderstorm watches in place for parts of the Great Lakes. Storms moved into the Chicago area in the afternoon, causing downed trees and some building damage. Elsewhere, barns collapsed in Wisconsin, buildings were crushed in rural northern Missouri and some large trees and power lines were downed in other areas across the Midwest.
