Rain and lake wind will prevent a repeat of yesterday's heat

There will be no repeat of yesterday’s heat and humidity here in Chicago as rain cooled air is teaming up with a lake wind to keep temperatures in check this afternoon.  Thermometers along Chicago’s lakefront are hovering in the 60s,  almost 25 degrees cooler than yesterday.   In addition to the cooler air, humidity levels have also dropped substantially.

At 12:30PM, a cluster of showers and thunderstorms over northeast Illinois continues to weaken and fade away. 

Additional storms are likely later today, especially along and south of Interstate 80. 

Storms weaken as they approach Chicago; damage reported in DeKalb
