Widespread light to moderate snow blankets parts of the region overnight, with the heaviest accumulation in Whittier at around 26 cm, signaling a high probability of a snow day and potential bus cancellations there. Inuvik and several eastern locations pick up 14 cm and 7 cm respectively, while wind remains generally moderate to breezy, with several spots in the 30–50 km/h range causing slick travel. Freezing rain or ice is not indicated, but gusty winds in Chicago (~52 km/h) and Mattice (~41 km/h) will worsen visibility and road conditions. For the morning commute, expect slick roads, extra time, and active bus checks; prepare kids early and monitor latest school announcements.
Stop relying on outdated “magic number” calculators. Snow Day Predictor is the 2026 standard for school closing probabilities, built on the same ultra-high-resolution weather engine that powers the world’s most popular smartphones.
While other sites give you a generic percentage based on total snowfall, we analyze hour-by-hour atmospheric changes to tell you exactly when the roads will become impassable.
Most snow day calculators use global models that only update every 6 to 12 hours. In a fast-moving winter storm, that data is obsolete before you even wake up. Our system leverages ultra-precision hourly data to track the “Morning Crunch”—the critical window between 4:00 AM and 7:00 AM that determines whether a superintendent calls for a closure or a delay.
