Across the morning, most areas stay under impactful accumulation with light snow totals under 10 cm for Ontario; Sturgeon Falls has about 7 cm with gusty 45 km/h winds, and nearby Michigan regions show a few centimeters. No freezing rain or blizzard conditions are indicated, so widespread bus cancellations aren’t expected. If you’re getting kids ready, expect a typical morning with some slick spots on untreated roads in northern Ontario and parts of the Great Lakes region, but no major school closures anticipated today.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
