Across the Great Lakes and Ontario, no widespread snow day is expected. Most regions report light snow totals well under 10 cm and only modest winds, so school closures are unlikely outside of isolated spots. In Sturgeon Falls, about 7 cm of snow with winds around 45 km/h and a chilly start around freezing may make for slick roads during the morning drive. Drivers should allow a bit extra time, especially if you’re near lake-effect zones. Otherwise, buses should run on time in the region with calmer conditions, but stay tuned for spotty flurries as you head out.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
