Chicago's average temperature this July will probably wind up at 27.2°C, making it the third-warmest in history behind 27.3°C 1921 and 27.4°C 1955. (Normal is 23.3°C.)
Along with the near-record heat we've had more 32°C days so far than ever before. And it's not over:
Never before, over the term of Chicago's 142 year observational record, have so many 90s accumulated at such an early date.
July alone produced 18 days at or above 90---far beyond the seven considered normal, yet just shy of the 19 days of 90s recorded in 1955 and 1987—both record highs for the month.
History tells us we've likely NOT seen the last of the hot air. An estimated 35 percent (more than a third) of Chicago's remaining 90+degree temperatures have typically occurred from this date forward.
At least today and tomorrow should be cooler, 27°C today and 28°C tomorrow, before going back into the red zone on Thursday.
Roll on October...
