CHICAGO (AP) — As a heat wave stretched into a second day this week, residents in more than half a dozen states are looking for ways to beat the heat amid hot soupy temperatures approaching triple digits. The National Weather Service has issued excessive heat warnings and advisories Tuesday in large patches of Illinois, Iowa, Missouri, Wisconsin, Michigan, Indiana, Ohio and Pennsylvania. Cities in multiple states opened cooling centers in response, including Chicago where temperatures were expected to close in on 100 degrees. Some schools dismissed students early. But relief was expected soon, with cooler temperatures expected starting Wednesday.
