Could you build this?
Partial The ZIP-code lookup UI is easy, but the forecast depends on a dataset of how districts actually decided closures, which the builder would have to collect and label themselves.
What it would actually take: The UI and lookup are a simple web app over a weather API. The hard part is building a labeled dataset of district closure decisions (historical closures, snow/ice conditions, district calendars) and training a calibrated classifier on it. Doing this well requires persistent data collection across seasons plus careful back-testing and calibration, and that data is not publicly available.
