A powerful band of heavy snow blankets northern Ontario, with widespread totals around 15–32 cm across many communities. Expect continued snowfall through the morning with gusts into the 40s–50 km/h, creating slick roads and reduced visibility. Given snow totals well into the high category, schools should brace for likely delays or closures, and bus runs could be affected in northern districts. Parents should plan extra time for getting kids ready and for possible transportation disruptions as crews clear major routes. Stay tuned for updates and road condition advisories as snowfall continues.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
