After temperatures hit 90 earlier today, the National Weather Service is saying we'll have a chance of storms tonight, perhaps as soon as 9 p.m.
The weather service has issued no warnings this evening, and rain is not certain.
The weather service expected the highest temperatures of the year today. It did hit 90 degrees at 2:55 p.m. at O'Hare, with winds gusting to as high as 30 mph.
But it'll be a different story Wednesday and the rest of the week, when we return to the perfect mid-70s, and maybe we'll hit the 80s over the weekend. The chance of rain increases as the week goes on.
