MADISON, Wis. (WMTV) - Today was a scorcher and for some of us, these high temperatures broke the previous daily record. Here are a few of the newest records for August 23rd: Prairie du Chien hit 104F (102F), Milwaukee 101F (98F) and Baraboo hit 101F (94F). But it wasn’t just the temperatures, heat index values were well above 115F with Janesville topping off at 123F real feel.

It will continue to stay sweltering overnight, and temperatures will slowly make their way down, but only into the high 70s. These temperatures coupled with the high humidity will make the overnight and morning hours very muggy and very uncomfortable.

What’s Coming Up...

Expect Thursday to be a very similar day to today with temperatures only slightly lower. Many of us will be at 95F or above with some still reaching over 100F. Heat index values will also be back in the triple digits. The Excessive Heat Warning continues for most of our counties through 7 pm Thursday evening.

Looking Ahead...

Early Friday we’ll be changing gears as a weak front pushes south and helps to cut temperatures by 10 degrees on Friday and then another 10 degrees into the weekend, giving us mild and slightly below-average highs in the mid-70s. Temperatures going into next week will stay on track, near 80.
