A Severe Thunderstorm Watch is in effect until 11 p.m. If storms develop, they could bring damaging winds and hail.

Chicago faces dangerous heat, air quality concerns

Chicago is facing another dangerously hot day, with temperatures and humidity combining to create a heat index that could reach as high as 115 degrees.

The extreme heat will ease slightly in the coming days. Wednesday through Friday will still be warm, with highs in the mid-80s, but the 90-degree streak will end. Scattered showers and thunderstorms remain in the forecast through the end of the workweek.

Looking ahead to Labor Day weekend, conditions appear favorable, with sunny skies expected from Saturday through Monday. Highs will be in the low to mid-80s on Saturday, dropping to near 80 on Sunday, and cooling to the low to mid-70s on Monday—ideal weather for the holiday weekend.
