The city of Chicago has officially tied a record for warmest heat index in recorded history, and also has hit 100 degrees for the first time in more than a decade.
As of 2:51 p.m. at O’Hare International Airport, the air temperature had reached 100 degrees, according to the National Weather Service.
That temperature not only ties a record for Aug. 24 that has stood since 1947, but also marks the first 100-degree day in Chicago since July 2012, according to officials.
Earlier in the day, O'Hare had registered a temperature of 79 degrees and a dew point of 79 degrees, according to the National Weather Service.
That combination made for a heat index of a staggering 118 degrees, tying July 13, 1995 as the warmest heat index ever recorded at the airport.
The 100-degree readings marks just the 66th recorded instance of triple-digit heat in the city, and the first 100-degree day in the city since July 6, 2012, according to NWS records.
