Winds ramp to blizzard strength with heavy snow bands sweeping the region, bringing 14–18 cm of snow in many spots. Expect whiteout conditions, rough morning commutes, and widespread bus delays or cancellations as gusts approach 90 km/h in several areas. Ontario and northern U.S. communities from Peterborough and Hartington to Wolfe Island and Sturgeon Falls face significant disruption; plan for kids’ morning routines accordingly and check school alerts before leaving.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
