Most areas stay quiet overnight with light accumulations below advising thresholds for a snow day. Ontario regions show only light snowfall totals (under 10 cm in Sturgeon Falls and Mount Forest) and occasional gusty winds (30–50 km/h) that could make slippery spots on untreated roads. No automatic school closures expected, though a few districts may see slow starts if roads are slick during the morning rush. Stay tuned for changes in gusty conditions near the Great Lakes and northern regions.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
