You're going to want to swap that pumpkin spice latte for an iced coffee this week.

The first day of October saw the mercury hit a high of 87 degrees in Chicago — and that had nothing to do with folks getting hot under the collar over the Bears' fourth-quarter collapse against the Denver Broncos. 

The unseasonable weather may have felt like August, but was still well below the record for Oct. 1 of 92 degrees set in 1971.

The forecast calls for temps to continue topping out in the mid-80s at the start of the week until a cold front swings through late Wednesday, according to the National Weather Service.

The scorching start to the month follows a September that was warmer than normal. 

National Weather Service data shows the average temperature for September in Chicago was 69.5 degrees, which is 3.2 degrees above normal. Even with the warmer average, no record highs were recorded in September. The highest average temp for September, by the way, was 71.2 in 1931.

For those who prefer their fall weather to deliver a crisp chill in the air, you'll get your wish by the weekend, when high temperatures are expected to drop to the 50s.
