Chicago, Illinois – Spring’s final mild day arrives Sunday before Illinois dives into a summer-like pattern of heat and humidity early next week, with scattered thunderstorms likely by Monday afternoon.
According to the National Weather Service in Chicago, temperatures will surge into the low 80s Monday through Wednesday, especially inland from Lake Michigan. Scattered storms are expected mainly south of I-80 on Monday, with additional rounds of thunderstorms possible Tuesday and isolated activity lingering into Wednesday.
Residents in Joliet, Kankakee, and along I-55 should stay alert for lightning and heavy downpours, particularly during afternoon and evening hours. Overnight lows will remain mild, hovering in the mid-50s to mid-60s, offering little relief from the humidity.
Travelers should prepare for potentially slick roads during storm periods and check local forecasts before heading out. Keep mobile devices charged in case of power outages and secure any outdoor furniture ahead of gusty winds accompanying stronger storms.
Storm chances may persist into the end of the week, with updated advisories possible. Stay tuned for the latest alerts as this warm and unsettled pattern continues.
