Chicago, Illinois – Breezy winds and a rising risk of scattered thunderstorms could disrupt plans in northern Illinois this weekend, especially for areas northwest of I-55 on Sunday afternoon.
According to the National Weather Service in Chicago, seasonable temperatures will persist through early next week, with highs ranging from the low 70s to upper 70s depending on proximity to Lake Michigan. Friday and Saturday will offer periods of dry weather, though scattered showers are likely south of I-80 Saturday afternoon. Sunday presents the highest chance for thunderstorms, particularly in McHenry, DeKalb, and northwest Cook counties.
Roadways near I-55 and I-88 could see reduced visibility and slick conditions late Sunday and again Monday afternoon as showers continue, especially in the western suburbs. Cooler lakeside air will keep temperatures closer to the 60s for Chicago proper, while inland highs approach 79°F.
Drivers should prepare for sudden downpours and check local alerts before heading out. Residents are advised to secure outdoor items and avoid travel during storms. Those near open areas or bodies of water should remain alert for lightning Sunday afternoon.
Thunderstorm chances continue into Monday, with the next significant system expected midweek.
