Powerful, prolonged snowfall continues from eastern Ontario into the Superior region with totals running 50–70 cm across many communities. Winds 60–72 km/h will drive whiteout conditions and blizzard-like gusts, especially where heavier bands set up. No freezing rain are present, but travel will be severely hampered and bus routes will be impacted. Sudbury and adjacent areas face Northern Storm Systems, while Lake-Effect regions like Espanola, Massey, Lively, Naughton, and Hanmer will see the most persistent whiteouts. Expect major delays, likely school closures or a snow day in many districts, with morning commutes nearly impossible in the heaviest bands. Parents should prepare kids for a potential day off and monitor local district alerts for bus cancellations.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
