Chicago woke up soggy on Saturday morning, April 4, 2026, with steady rain, low clouds and patchy fog hanging over the city and temperatures near 46°F at Midway. A Flood Watch is in effect through 10 AM CDT, and showers and scattered thunderstorms, some packing heavy downpours, are expected through the late morning. The mix of heavy rain and gusty winds could slow commutes, cut visibility and trigger quick ponding on low-lying streets.
Morning Downpours And Flood Watch
Showers and thunderstorms are likely before 1 PM, with new rainfall totals of roughly three quarters to one inch possible in the stronger cells, along with southwest winds of 15 to 20 mph and gusts up to 30 mph, according to NWS Chicago. The Flood Watch runs through 10 AM CDT Saturday, April 4, 2026, and forecasters say already saturated ground from recent rain will boost the odds of rapid runoff in urban areas.
Afternoon Winds Pick Up
Behind a quick-moving cold front, winds will swing around to a more westerly direction and stay blustery into the evening. That could send unsecured outdoor furniture skidding across backyards and make highway driving feel choppy. Temperatures will ease into the low 50s through the afternoon as the front moves through.
Commute And Lakefront Impacts
Nearshore Lake Michigan waters are expected to turn rough, with a Small Craft Advisory in effect from mid-morning Saturday into Sunday. Recreational boaters are urged to skip the lake today or stay close to shelter. On the roads, build in extra travel time, keep the wipers working and avoid driving through standing water. If you see floodwater ahead, turn around and find another route instead of rolling through it.
What To Do
Tie down patio furniture, pull lightweight items inside and put off nonessential lake outings for another day. Check local transit alerts before heading out and give street and highway crews some room to work once the heaviest rain shifts east.
