Where school is most likely to close today
nationwide
Nothing anywhere in the country meets snow day criteria right now — no measurable snow, no ice and no dangerous cold in the next 24 hours. That is normal outside of roughly November to March. This board fills up within hours of the first winter storm, so it is worth bookmarking before the season starts. Meanwhile the calculator above still works for any town: it will simply return a low number until snow shows up in the forecast.

How this snow day predictor works
Most snow day calculators ask for your ZIP code and then produce a number that has nothing to do with the weather. This one starts from the actual forecast for your town: how much snow falls between evening and the morning bell, when it starts, how cold it gets, whether freezing rain is in the mix, and how hard the wind blows. Those are weighed against what districts in your part of the country actually do — a Georgia district calls it off at an inch, a Minnesota district runs buses through six. Ice matters more than snow, because a quarter inch of glaze shuts roads that eight inches of powder would not. Timing matters almost as much: snow that starts at 2 a.m. closes schools, the same snow starting at 10 a.m. does not. It is still a forecast, not a decision — superintendents call it around 5 a.m. based on what is actually on the pavement.
