Snow is light to moderate overnight with a notable pocket near Sturgeon Falls, ON where about 7 cm has fallen under hazy skies. Winds to 45 km/h will make for a breezy morning in places, but there’s no broad school-closure signal today. Expect slick spots on untreated roads, especially in northern Ontario, while most areas stay just watchful rather than outright disruptive. Precipitation continues to mix through the period, so keep a light coat handy and give yourself extra time for the morning commute in the north.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
