CHICAGO, Ill. – Streetlights glint off slick pavement this early Sunday morning as a cold drizzle sweeps in from Lake Michigan. The hum of traffic on I-90 rises through the mist, and tree limbs sway under the first gusts of a blustery fall front. By sunrise, much of Chicagoland will be dealing with periods of steady rain, dropping visibility and making morning drives slower than usual.
The National Weather Service in Chicago reports widespread showers across the metro area, with the heaviest rain tapering after midday. Gusty northwest winds will follow this front, reaching 25 to 35 mph and signaling the arrival of cooler, drier air. Temperatures will hold in the 50s through most of Sunday before dropping into the 40s tonight under clearing skies.
Monday brings a quick rebound — sunny and breezy, with highs in the mid-60s and wind gusts near 20 mph. It’s the best window for outdoor work or cleanup after a soggy weekend. But don’t get too comfortable: another system approaches Tuesday, bringing scattered showers and another cooldown by midweek.
By Wednesday and Thursday, highs will settle into the low-50s with brisk winds and a mix of clouds and sun. Late-week nights may flirt with the 30s inland, hinting at the city’s first early frost potential. For now, keep those jackets handy and watch for slick spots — the kind of classic Chicago weather swing that makes fall both challenging and memorable.
