Morning update: most areas stay quiet, with only light snow pockets in Sturgeon Falls, ON (about 7 cm total) and some breezy conditions around 40–45 km/h. No freezing rain or ice reported, so school buses and morning commutes should run as usual. Stay alert for slick spots on untreated roads in the early hours, but overall the day looks normal for most districts.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
