The Union of Concerned Scientists has a new report out:
Heat in the Heartland
60 years of warming in the Midwest

They chose several states across the midwest as examples in the report. Here's
what NOAA's Climate at a Glance shows for maximums temperatures May through
October for Missouri, Illinois, Indiana and Ohio:

Minnesota only shows cooling summertime max temps since 1930
Here's a map of what that all looks like:
