90 degree heat is no stranger to Chicago’s weather scene. After all, the city typically sees an average of 17-21 90-degree-plus days each year.
But, what sets this hot spell a part is its duration and early arrival. A string of at least four days of 90 degrees or higher has not occurred this early in the season since 1999 when 90s were logged June 8th thru 11th .
However, if current forecasts verify, a string of five days in the 90s would make this the longest early season hot spell in four decades—since a 9-day string May 16-24, 1977.
While no new record highs are anticipated, temperatures are expected to approach the old benchmarks on Monday and Tuesday.
