Minnesota and the Dakotas are very similar culturally, and everyone agree that Minnesota is upper midwestern. Wisconsin has to go with Minnesota and if you include Wisconsin you should include Michigan as well. Iowa is a hybrid of Minnesota and Nebraska but in my opinion belongs more with Minnesota. Northern Illinois belongs in the upper Midwest. Central Illinois, most of Indiana, parts of Nebraska, Northern Missouri, and parts of Iowa form their own band of pretty similar culture. Southern Illinois, southern Indiana, large parts of Missouri, as well as parts of Kentucky have a hybrid lower Midwest upper south culture that is still primarily midwestern.
