Illinois – Low clouds hang over Chicago this morning, but a quick warm surge is already building, setting up a sharp swing in conditions within hours. Streets feel damp, and visibility may shift quickly as the day unfolds.
According to the National Weather Service, temperatures climb to 76°F today as clouds break and southwest winds increase. Gusts could reach 25 mph by afternoon, pushing in unseasonably warm spring air across northern Illinois.
That warmth does not last long. By late Sunday morning, rain develops with a 40% chance, paired with patchy fog that could reduce visibility on I-90, I-94, and Lake Shore Drive. Winds strengthen further, gusting up to 30 mph, creating slick roads and slower travel.
Drivers should plan extra time Sunday, especially through the late morning and midday hours. Wet pavement and reduced visibility could lead to sudden slowdowns. Keep headlights on and allow extra following distance.
Behind the system, colder air quickly returns. Monday drops to near 40°F with clearing skies but a brisk feel. Winds ease slightly, though the cooler air settles in across the Chicago metro.
By Tuesday, conditions stabilize with highs near 54°F under mostly cloudy skies. Midweek remains mild but gray, with another chance of showers arriving by Thursday.
This back-and-forth pattern reflects early spring across the Midwest, where warmth and cool air collide quickly. Keep layers handy and monitor changing road conditions. Are you seeing fog or wet roads in your neighborhood yet?
