Widespread light to moderate snow blankets Ontario and the Great Lakes region with Sturgeon Falls picking up about 16 cm and winds around 45–50 km/h, signaling potential delays for northern routes and morning bus runs. Most areas will see 7–12 cm with lighter winds, so expect patchy slick spots on treated roads and slower commutes as kids are getting ready. No freezing rain signals in this batch, but gusty winds will sustain reduced visibility in heavier bands. Stay alert for evolving conditions into the late morning as snowfall diminishes in some zones and road crews work to clear main highways.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
