An unsettled wake-up across the region brings light snow generally under 10 cm, with the heaviest totals near Markdale, ON (about 9 cm) and parts of the northern tier of the Great Lakes. Winds stay mild for most areas, keeping gusts under 60 km/h, so blizzard conditions are not expected. Travel may be slick in spots where snow has lingered on untreated roads, and some areas could see drizzle or rain mixing in, especially farther south. For families, plan a cautious morning routine, check local school alerts, and allow extra time for bus runs in affected pockets.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
