Widespread heavy snowfall totals around 14–17 cm with gusty winds 40–72 km/h will create slippery roads and blowing snow from the Maritimes through the Upper Midwest. Several locations show high snow accumulations with strong winds, leading to blizzard-like conditions in the strongest spot (St Anthony, NL) and a clear risk of bus cancellations in many districts. Expect slick untreated surfaces, reduced visibility at times, and a agencies-led response. This means a good chance of school delays or closures in affected areas; parents should plan for getting kids ready and checking local school alerts before heading out this morning.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
