Widespread heavy snow blankets northern and central Ontario with continued precipitation overnight. Totals top 25 cm in several communities (South Porcupine, Chaput Hughes, Sturgeon Falls) and remain heavy into the morning, with continued light to moderate snow across the region. Temperatures near -3 to -1°C and winds generally 45–55 km/h will keep roads snow-covered and reducing visibility. Expect significant impacts to the morning commute and bus runs; many districts are likely to announce school delays or closures. Parents should plan extra time, lay out winter gear, and monitor local alerts for changes in schedules.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
