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.
