Winter’s grip remains across northern Ontario with light to moderate snow totals generally in the 5–9 cm range from Kapuskasing, Constance Lake, Opasatika, Hearst, Mattice, Jogues and Cartier. Winds will be blustery, 40–55 km/h, creating blowing snow at times and reducing visibility on rural roads. No widespread school closures expected, but a few northern school districts may opt for delays or bus adjustments if gusts shorten visibility or worsen road conditions. Stay with local alerts for your area.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
