Widespread heavy snow blankets Wisconsin and parts of Iowa, with 20–24 cm already reported in many locations and continued snowfall through the morning. Winds 50–60 km/h will reduce visibility and create drifting, making the morning commute and school bus runs challenging. Plan for delays or early dismissals in the hardest-hit districts; keep kids bundled and allow extra time for travel and drop-off. Snow transitions to slower, patchy bands later, but travel remains hazardous through the 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Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
