A light to moderate snowfall will blanket parts of Ontario, with Sturgeon Falls reporting about 7 cm. Winds around 45 km/h keep visibility limited at times, but no blizzard conditions are expected today. For the morning commute, plan for slick roads and slight slowdown; most districts won’t see heavy blowing snow, but motorists should allow extra time and parents should prep kids for a possible bus delay. Snow should taper through the morning, with reduced impacts by afternoon.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
