Snow blankets the region with pockets of heavier totals, notably Sturgeon Falls, ON at about 16 cm, while nearby Dunrobin, ON sees around 8 cm. Most Ontario and Great Lakes areas expect 7–10 cm, which will slow commutes and put bus runs at risk in northern corridors. Strong winds crest over Newfoundland locations (up to 70–85 km/h) and will drive blowing snow, reducing visibility at times and complicating school drop-offs further east. While Ottawa and southern Ontario look calmer, crews should brace for slick roads, slower travel, and potential early delays in spots that see higher accumulations. Road crews and parents should plan extra caution for getting kids ready and into a snowy school day.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
