Mateo Elias is the founder, primary writer, and editor of Snow Day Stats. Every article here is written or reviewed by him, and he is the person accountable for what appears on this site. The project began with a small frustration. A popular snow day calculator showed a 92 percent chance of closure. School opened on time. The forecast had not been wrong in any obvious way, so something else was going on. The answer, it turned out, was not in the weather at all. It was in the district's own operating rules and in the hour the snow arrived.
