Overall, most regions see light to minor snow with modest winds; Sturgeon Falls, ON holds the most noticeable snowfall at around 7 cm, but the overall pattern suggests little to no school closures. Winds in the Ontario area are moderate (around 45 km/h in Sturgeon Falls), with stronger gusts in eastern regions like Port Hope Simpson, NL and Lestock, SK well above the doorstep of disruption but not affecting Ontario’s morning commute heavily. Expect dry roads in many places, but keep an eye on local gusts as some coastal and northern zones can feel breezy. Parents should plan a typical school morning with a light snowfall in Ontario but unlikely bus cancellations in the immediate region.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
