A forecast and a school closure are two different things: the first comes from a weather service, the second from a superintendent or school board early in the morning. These calculators keep the two apart. They show the forecast figures, where they came from and when, and turn them into an openly heuristic estimate you can adjust, next to the official formulas for wind chill.
