Monday will see partly sunny skies with hot and humid temperatures, topping out around 88 degrees. Clouds will increase overnight, setting the stage for more off-and-on showers and thunderstorms that could linger into Tuesday.
Muggy air and afternoon showers or storms remain likely through Wednesday.
By next weekend, highs climb back into the low to mid-90s, as the dog days of late summer continue to bring heat and humidity to Chicagoland.
Total precipitation through Wednesday evening
Gargantuan rainfall totals are possible across northern Missouri, eastern Iowa and western Illinois, as a stationary front brings repeat rounds of thunderstorms.
Across the Chicago area, current modeling suggests 1 to 2 inches may be possible, but locally heavier in some areas due to thunderstorms.
6-10-day temperature outlook
Another round of hot weather is possible later next week, according to the latest suite of computer models. The Midwest and Northeast have a high likelihood of seeing above to potentially much above normal temperatures during the Aug. 14-18 period.
