Episode Narrative A hot air mass settled over southern Wisconsin to start the month of July, bringing 100-degree heat to many locations for multiple days between July 2nd and July 6th. While humidity levels were relatively low considering the temperatures, maximum heat indices still climbed to between 100 and 115 during the hot spell. Milwaukee and Madison each recorded two of the top-ten hottest days on record on July 4th and July 5th. An elderly woman in Rock County and an elderly man in Dane County died due to the heat. Additionally, as of 09/30/12, there were other possible heat-related cases still pending: 6 in Milwaukee County, 1 in Columbia County, 1 in Waukesha County, and 2 in Rock County. Dozens of people across southern Wisconsin were brought to hospitals with heat-related illnesses, however, the exact number is unknown.

The counties surrounding Dane had 4 days of 100 degrees or higher, while counties toward Lake Michigan had 2 or 3 days. The cites of Janesville, Kenosha, Middleton, Sullivan, and Paddock Lake topped out at 106 degrees, which was Wisconsin's highest temperature for the 2012 summer season. Numerous new daily record highs were set as well as record high minimums. The long duration of this excessive heat period makes this probably one of the four most dangerous heat waves to strike southern Wisconsin in recorded history.
