Overview

• A stalled frontal boundary will sustain isolated showers and thunderstorms through Saturday with the highest rain chances south of I-80.
• Inland highs are expected to near 80°F Friday and Saturday while lakefront areas remain cooler in the 60s and low 70s under onshore breezes.
• Wildfire smoke from Canada has degraded air quality across much of Chicagoland, pushing levels into the unhealthy-for-sensitive-groups category.
• Updated projections call for partly cloudy skies and highs in the low to mid-80s on Sunday as conditions improve for Father’s Day.
• Early next week may bring a more organized storm pattern alongside a return to summerlike temperatures and increased humidity.
