CHICAGO  (CBS) –Welcome to a mid-summer scorcher, Chicago.

Of course it’s not close to mid-summer.  As of 3:02 p.m. on Friday, summer officially becomes fall.

Yet, Chicago is in the middle of a record-setting heat wave.

Late September is seeing near-record or record warmth across the Midwest, including northern Illinois and Indiana.

Chicago set a record for daily heat on Wednesday, Thursday and Friday and could set more through the weekend, according to the National Weather Service.

Wednesday’s high of 92, broke an 86-year-old record by one degree.  Thursday was even hotter, with a high of 94, breaking a 47-year-old mark by two degrees. And while the low temperatures for those days were a bit sticky, no records were set.

As of 2:30, Friday’s mark topped the old record by two degrees.

Here are the current records for high and high “low” temperatures for the next four days.

Sept. 22: 92 (1956) 73 (1895)
Sept. 23:  91 (1937) 71 (1891)
Sept. 24: 91 (1891) 71 (1930)
Sept. 25: 90 (1933) 76 (1931)

It had been 10 years since Chicago has experienced 90 plus degrees this late in the year, the NWS said.

The latest 90-degree reading on record?  Oct 6, 1963 (94 degrees)

The hottest days ever in September? Chicago has hit 100-101 degrees four times.

September 1, 1953: 101

September 2, 1953: 101

September 7, 1939: 100
