Chicago: a short snow burst can matter
Chicago-area winter travel is not only about the final snowfall total. NWS Chicago’s January 2026 snow-squall review describes a morning burst with rapidly falling temperatures, strong winds and sharply reduced visibility. The timing and intensity of a brief event can matter even when it is much shorter than a large regional snowstorm.
The forecast above separates the next two school days and shows all four modeled school outcomes. Read the explanation alongside the percentages, particularly when winter weather overlaps arrival or dismissal. If your commute crosses into a suburb, use that locality’s forecast as well as Chicago’s. This page is a planning tool, not a report of road conditions or a Chicago Public Schools announcement; schools and districts make their own decisions.
