Intermittent snowfall continues across Ontario with most spots picking up 8–16 cm and several northern locations near the 15 cm mark, bringing scattered road slush and slick spots for the morning commute. The strongest winds are in Sturgeon Falls (about 48 km/h), with others in the 30–40 km/h range, producing gusty conditions and reduced visibility on local roads. Because several northern districts are averaging 8–16 cm, plan for possible delays today, especially in higher terrain and rural bus routes. If your region sees approaching heavier bands, expect longer waits and slower buses. Stay with local updates for any school-specific closures, particularly in northern Ontario where higher snowfall is concentrated.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
