People in and around Chicago should prepare for a hot and sticky Sunday as temperatures soar and afternoon thunderstorms may roll in. According to the National Weather Service, the heat index could reach close to 100°F (around 38°C), especially in areas northeast of I-90.
Storms Likely in Lake, McHenry, and Cook Counties
Starting after 4 p.m. on Sunday, scattered thunderstorms are expected to form, mainly in Lake, McHenry, and Cook counties. Some of these storms might become strong, bringing gusty winds that could knock down tree branches or cause minor damage. These storm chances may extend into the night and continue along I-80 on Monday.
High Temperatures and Sticky Nights
Chicago could experience high temperatures near 94°F (around 34°C) on Sunday, with warm nighttime temperatures around 75°F (24°C). Other nearby cities such as Joliet, Waukegan, and Kankakee should also watch out for sudden, heavy rain and possible short power cuts due to the weather.
People traveling on interstates like I-57 and I-80 should be careful on Monday morning, as heavy rain might reduce visibility and cause delays.
Safety Tips for Residents
Authorities are advising people to stay indoors during the hottest parts of the day, drink lots of water, and avoid strenuous outdoor work. If you don’t have air conditioning, consider visiting a nearby cooling center to stay safe from the heat.
Relief Coming Tuesday
The good news is that cooler and less humid air is expected to arrive by Tuesday. Daytime temperatures will drop to the upper 70s°F (around 25°C), and dry, pleasant weather is likely to continue through midweek.
Chicagoans and people across northern Illinois should take this heat and storm warning seriously. Stay indoors if possible, keep cool, and watch for weather updates. With high temperatures and possible thunderstorms, it’s important to take precautions and stay safe until cooler air returns on Tuesday.
