Widespread heavy snow and brisk winds grip the region tonight, with Newfoundland and Labrador seeing widespread snowfall totals generally in the 9–18 cm range and gusts often around 70–90 km/h, creating blizzard-like conditions in places. Ontario’s northward zones, notably Sturgeon Falls (≈16 cm) and other areas with heavy snow, will face persistent snowfall and gusty winds into the morning, raising travel hazards and possible school delays. The combination of heavy snow and strong winds means slick roads and reduced visibility, so plan for delays, buses running late, and extra time for a cautious morning commute as kids head to school.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
