Expect light snow flurries across Ontario with modest accumulation near Sturgeon Falls (roughly 7 cm overall this period). Winds around 40–45 km/h could make roads feel brisk, but no broad snowfall alarm. Morning commute may have slick spots early, yet widespread bus and school operations should largely run on time. Dress warmly and allow a few extra minutes for cautious driving as the day begins to clear in spots.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
