Illinois – Loose patio furniture rattles and tree branches sway sharply across the Chicago area this morning as strengthening south winds signal a turbulent weather day ahead. Gusts approaching 50 mph by mid-afternoon could disrupt travel and briefly threaten power lines across northeastern Illinois.
According to the National Weather Service in Chicago, a Wind Advisory remains in effect from 1 p.m. until 9 p.m. Sunday for Cook, DuPage, Kane, Kendall, and Lake counties. Sustained winds between 20 and 25 mph will build through the afternoon, with stronger gusts capable of knocking down small limbs and sending unsecured objects across streets and parking lots.
Drivers should prepare for sudden crosswinds, especially along I-55, I-90, and elevated roadways near Lake Michigan. High-profile vehicles may struggle to stay steady on west-to-east roads. Secure outdoor decorations, trash bins, and loose construction materials before the strongest gusts arrive.
Storms may also develop late today as a powerful cold front sweeps toward the Midwest. Meteorologists say a few storms could carry damaging wind gusts approaching 70 mph and small hail, mainly later this afternoon and early evening.
Conditions change quickly after sunset. Rain transitions to a rain-snow mix early Monday, followed by patchy blowing snow and sharply colder air. Visibility may drop briefly on open roads west of Chicago as northwest winds increase behind the system.
Looking ahead to St. Patrick’s Day Tuesday, brighter skies return but temperatures stay brisk across the region before a gradual warmup later in the week hints at early spring.
Plan extra travel time today, keep both hands on the wheel during strong gusts, and stay weather-aware as the storm system moves through. Additional advisories could be issued as the cold front approaches.
