CHICAGO, Ill. – NOAA’s newest winter outlook, released Thursday, Oct. 16, shows Illinois bracing for a cold, stormy start to 2026 — with multiple snow and ice events likely between January and March. The Climate Prediction Center’s guidance points to above-normal precipitation and below-normal temperatures statewide, a setup consistent with La Niña winters that bring frequent Midwest storm tracks.
According to the National Weather Service in Chicago, “This season looks active, especially across northern and central Illinois. Several systems could bring heavy snow or mixed precipitation through February.” Cities like Rockford, Peoria, and Bloomington are expected to see the most consistent snow, while southern areas near Carbondale may see alternating rain and sleet.
Lake-effect snow could also enhance totals for northeastern Illinois during northwest wind events. The coldest stretch is expected in late January and early February, when Arctic air could plunge daytime highs into the teens. Travel impacts are likely along I-55, I-57, and I-80, where frequent freeze-thaw cycles could lead to icy conditions and black ice overnight.
Forecasters caution that March may stay colder than average, delaying the spring melt and prolonging snow cover across the northern half of the state. Residents are urged to check furnaces, insulate pipes, and stock emergency supplies ahead of the first major system.
For Illinois, Winter 2026 looks cold, long, and snow-packed — a true return to classic Midwest winter conditions that will test endurance well into March.
