Heavy to moderate snowfall blankets a broad stretch from Summit to Endicott, with several towns at or near 21 cm and most areas seeing 10–20 cm. Winds of 30–40 km/h will create blowing and drifting on exposed roads, with gusts up to around 43 km/h in some spots. This combination means slick, slow morning commutes and a high likelihood of school delays or closures in districts covering Summit, Davenport, Westford, Madison, and neighboring towns. Expect continued snowfall through the morning, with improving but still slick conditions as the day progresses. Parents should plan extra time for getting the kids ready and for potential bus cancellations in higher-snow areas.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
