A light to moderate snow event continues across Ontario with the most noticeable accumulation near Sturgeon Falls, clocking roughly 7 cm today and winds around 45 km/h that could slow the morning commute. Other Ontario spots like Wunnumin Lake and Cochrane pick up under 2 cm with lighter breezes. No freezing rain shown, so buses aren’t expected to be cancelled, but keep a cautious drive in light to moderate snowfall. For families, plan for a slower start and give the kids extra time getting ready, especially if you live near the highlighted Ontario zones whose roads may be slick early on.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
