Illinois weather turns tricky today as light snow brushes the Wisconsin state line and cold pavement threatens to turn wet roads slick by midafternoon. Drivers north of I-90 could encounter brief snow showers before 3 p.m., with temperatures sliding toward 32 degrees. Even minor bursts may coat overpasses and untreated ramps.
According to the National Weather Service in Chicago, a 30 percent chance of snow will linger into early afternoon, mainly north of the city. Northeast winds between 10 and 15 mph, gusting near 25 mph, will add a biting edge. Forecasters flag locally slippery travel, especially on elevated roadways near the Illinois–Wisconsin border.
In Chicago, skies stay mostly cloudy with highs near 35 degrees before colder air settles in tonight. Blustery conditions continue after sunset as temperatures dip into the upper 20s. That setup raises a flash-freeze concern where melting snow refreezes on bridges and exit ramps. Plan extra time if heading out later today.
Sunday keeps a late-winter feel. A slight chance of snow showers develops before noon, then clouds hold steady with highs near 30. By Monday, sunshine returns and temperatures rebound to around 40, signaling a gradual shift as March arrives.
Rain chances increase Monday night into Tuesday, with highs climbing into the upper 30s and low 40s. Midweek brings additional rain and readings in the 40s, hinting at early spring warmth building into the 6–10 day outlook.
