South of Chicago, an ice jam in the Kankakee River broke apart, triggering flash flooding in the Wilmington area. Authorities told residents to immediately move to higher ground.

In Illinois, a foot of snow fell in Manito, in the central part of the state, the Weather Prediction Center said late Thursday. In Kansas and Missouri, snowfall totals reached 10 inches.
