Widespread heavy snow persists with gusty winds across Ontario and the Northeast, creating slick roads and slow commutes. Snow totals of 18–28 cm are common from River Valley, ON to Saint-Raymond, QC and Rimouski, QC, with several spots flirting with blizzard-like winds around 60–70 km/h. Expect persistent snowfall through the morning, reduced visibility at times, and plow/Snow Removal activity in progress. Given the totals, there is a high likelihood of snow day impacts in exposed areas and significant bus schedule disruptions; plan for school delays or closures where accumulation is heaviest, and give kids extra time to get ready despite the tempting to rush. If you’re in Barrie/Owen Sound or nearby, the classic Lake Effect pattern will complicate timing, so stay tuned for updates.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
