Showers of light to moderate snow are possible across northern Ontario with a notable case around Sturgeon Falls where about 7 cm have fallen and winds near 45 km/h will create blowing snow and slick highways. There’s no widespread shutdown expected, but a few remote or northern districts could see minor delays as buses struggle on untreated routes; parents should plan extra time for the morning commute and getting the kids ready. Overall conditions stay cold and unsettled, with limited snow elsewhere in Ontario and softer conditions in the south.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
