Light to moderate snow and chilly conditions linger across parts of Ontario this morning, with Sturgeon Falls picking up about 7 cm and winds around 40–45 km/h keeping roads slick. Precipitation continues through the period, and haze will reduce visibility at times. No widespread closures expected, but the moderate snow in Sturgeon Falls means bus runs could be delayed and morning commutes may take longer, so plan for extra travel time for the kids and school corridors north of the GTA.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
