Chicago, IL – Summer heat and storm risk are both on the rise across Illinois, with 88°F temperatures and Tuesday night thunderstorms setting the tone for June.
According to the National Weather Service in Chicago, limited thunderstorms could develop late Tuesday, June 3, as a frontal system pushes southeast at 45 mph. While severe weather is not expected, locally gusty winds and lightning are the main concerns, especially near Lake Michigan and the I-90 corridor.
By Sunday, June 1, highs will climb into the mid-60s across the city, with dry skies and mostly sunny conditions through Monday. Winds shift from the northeast to southwest as temperatures rise sharply, reaching 86°F by Monday and peaking at 88°F Tuesday afternoon. The heat will prime the atmosphere for isolated storms late Tuesday night into Wednesday, with a chance of showers continuing through Thursday.
Drivers should stay alert for potential delays along I-290, I-90, and U.S. 41 during the Tuesday evening rush. With strong winds forecast, securing outdoor furniture and checking storm drains is advised.
Chicagoans can also expect hazy skies early this week due to lingering Canadian wildfire smoke, which could limit visibility and impact air quality.
Five-Day Outlook (June 1–5):
- Sunday: Mostly sunny, high 64°F
- Monday: Sunny and hot, high 86°F
- Tuesday: High 88°F, chance of thunderstorms late
- Wednesday: Showers and storms, high 77°F
