Chicago, IL – Temperatures will fall तेजी after sunset Sunday, dropping below freezing by midnight in outlying areas and creating frost that could impact early Monday travel and sensitive vegetation. Bridges and overpasses may develop slick spots, especially along I-90, I-88, and I-55 during the pre-dawn hours.
According to the National Weather Service in Chicago, breezy conditions and scattered showers Sunday afternoon will give way to the coldest air of the stretch overnight. Lows are expected to reach 27 to 36 degrees outside the city, while Chicago itself holds slightly warmer in the low to mid-30s. Frost development is likely in suburban and rural areas.
Communities including Aurora, Joliet, Elgin, and DeKalb face the highest risk of sub-freezing temperatures. Winds may remain elevated into the evening before easing overnight, allowing temperatures to drop quickly. Any leftover moisture from afternoon showers could freeze on untreated surfaces, creating patchy icy conditions on local roads and sidewalks.
Residents should cover or bring in sensitive plants and ensure pets are protected from the cold. Drivers are urged to slow down during early Monday travel and watch for isolated slick spots, particularly on elevated roadways.
Cold conditions persist into Monday morning, with gradual warming expected by Tuesday afternoon. Additional updates may be issued if frost advisories expand across northern Illinois.
