Illinois – Wet pavement reflects traffic lights across the city as mild air hangs on early this morning. It feels more like late fall than January, but winter is waiting just behind it.
According to the National Weather Service, rain develops across Chicago today as temperatures climb into the low 50s. Steady southerly winds add a damp chill, and visibility may drop during heavier rain bands. Roads across Cook County could stay slick through much of the day, especially during busy commute hours.
Conditions remain unsettled into tonight. Rain lingers, winds strengthen, and temperatures slowly fall. Gusts near 30 mph may push water across low spots on roadways and create difficult driving for high-profile vehicles along I-90, I-94, and Lake Shore Drive.
By Friday, the system weakens but doesn’t leave quietly. Clouds hold firm, scattered showers continue, and highs slip back into the mid-40s. The air turns noticeably colder by evening, setting the stage for a sharper weekend change.
Saturday is the key day to watch. Rain is expected to redevelop, then transition to snow as colder air deepens. While heavy accumulation is not guaranteed, even light snow can cause problems. Slushy roads may refreeze quickly after dark, raising black ice concerns across city streets and suburban highways.
Saturday night brings a better-defined snow chance, with temperatures dropping into the 20s. Side streets, bridges, and untreated surfaces could turn slick fast. Drivers should plan extra time and reduce speed.
Sunday trends quieter but colder. Skies brighten, highs struggle near 31, and winter finally takes control. Early next week stays seasonably cold, with dry conditions returning.
Meteorologists continue tracking the temperature drop closely. Timing will matter. Traveling this weekend? What are you seeing on Chicago roads?
