Overnight snowfall totals reached the 12–22 cm range in several western and northern regions, with Stewart, BC at 22.6 cm and Iqaluit, NU at 20.1 cm; winds peak around 40–63 km/h in exposed areas. No Ontario data crosses the 10 cm threshold, so widespread Ontario school closures aren’t anticipated, but expect a potential sluggish morning commute where lake-effect snow or lingering plowable snow remains on roads. Stay tuned to local school and transportation alerts for any last‑minute delays or bus changes.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
