Official 90º tally is on par with last year’s total and what’s typical by July 11—but the mercury has yet to reach the hot 90° weather benchmark so far this month at O’Hare
Since records began 66 years ago at O’Hare, only 14 other years have failed to reach 90+ degrees the first 11 days of July. A typical FULL July sees about eight 90 degree or warmer days.
Heat and humidity build over the weekend and continue through Tuesday…
Sunday forecast highs:
- 260 million residents forecast to see high temperatures at or above 90 degrees
- 26 million residents to see high temperatures at or above 100 degrees
Monday forecast highs:
- 261 million residents predicted to see high temperatures at or above 90 degrees
- 27 million residents to swelter in triple digit temperatures
Tuesday forecast highs:
- 251 million residents predicted to reach 90 degrees or warmer
- 36 million to swelter in stifling 100 degree or warmer temperatures
