Across the Great Lakes and Ontario, light to moderate snow accumulations (roughly 8–10 cm in many spots) combine with gusty winds in the 40–60 km/h range. While most areas won’t see a widespread snow day, expect morning slick spots and potential bus or school-delays in pockets where snow is heavier or winds are strongest, notably near Little Current, Sundridge, Fordwich, and Magnetawan. Winds up to around 60 km/h will create reduced visibility and drifting in open areas. Where freezing temperatures linger, treat sidewalks and driveways with extra caution. Stay with SnowDayPredictor for updates as road conditions evolve.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
