Widespread heavy snow overnight has dumped 15–21 cm across the Northeast, with gusty winds helping to keep roads slippery. Expect many districts in Massachusetts, New Hampshire, Connecticut and Vermont to consider school delays or closures, especially where totals top 15 cm. Morning buses will be slow or canceled in places with the heaviest snowfall, so plan extra time and get the kids ready early. Roads will remain slick into late morning as snowfall continues in pockets, so use caution and check your local district alerts before heading out.
Stop relying on outdated “magic number” calculators.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 In a fast-moving winter storm, that data is obsolete before you even wake up.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.
