As forecast yesterday, Chicago's temperatures today haven't even approached normal July levels. Right now O'Hare reports 16°C after a high at noon of just 18°C. That's normal for October 10th; for July 27th, the normal high is 29°C.
As it's unlikely the temperature will rise much due to the cloud cover and stiff wind off the lake, it looks like we've set a new record low maximum, two degrees below the previous record of 21°C.
Great walking and sleeping weather, though.
Remember, last July was the second-hottest on record for us.
