We’re tracking light to moderate snowfall across parts of Ontario this morning, with Sturgeon Falls seeing about 7 cm and winds around 40–50 km/h. Roads will be slick, and lingering snow may slow the morning commute. Schools in affected areas should monitor for delays; buses may run on a delayed schedule as crews work to clear routes. Expect potential getting-the-kids-ready routines to take extra time in the first part of the day.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
