ABC7 meteorologist Tracy Butler says high temperatures are expected to reach the 80s for the first time this month at O'Hare. After as much as a 40-degree separation in temperatures Wednesday, numbers around the area will be closer Thursday, even with a slight lake-breeze.
Our average high today is 68. While a warm front has brought the warmth and possibly a few showers during the day Thursday, a cold front will usher in a slight risk for strong thunderstorms, especially Thursday night.
Don't be surprised if you hear some hail along with the rain from the storms, Butler said.
