CHICAGO -- A heat wave might soon come to an end, but it had one more record to break on Tuesday as the temperature hit 91 at Chicago's O'Hare International Airport, marking the seventh day in a row of unprecedented heat, CBS Chicago reports.

The official temperature for Chicago continued climbing to 92 Tuesday afternoon, according to the National Weather Service, which announced the news on Twitter. The previous record for Sept. 26 was 90 degrees, set in 1998.

In addition to 90°+ stats, #Chicago hit 92° today, 7th consecutive day of 92°+. Only 10th time on record overall with 7+ days of 92°+. #ilwx — NWS Chicago (@NWSChicago) September 26, 2017

It was the seventh consecutive day of temperatures in the 90s in Chicago — the longest such stretch this year. All seven days were record highs for their respective dates:

Monday's high of 92 beat the Sept. 26 record of 90 set in 1933



Sunday's high of 93 beat the Sept. 24 record of 91 set in 1891



Saturday's high of 95 beat the Sept. 23 record of 91 set in 1937



Friday's high of 94 beat the Sept. 22 record of 92 set in 1956



Thursday's high of 94 beat the Sept. 21 record of 92 set in 1970



Wednesday's high of 92 beat the Sept. 20 record of 91 set in 1931



By comparison, there was only one day in all of August when the temperature reached 90 in Chicago, only two in July, and only six in June. Before this past week, the longest streak of 90-degree days in 2017 was a three-day stretch in early June.
