Powered by NOAA / National Weather ServiceElderberry Elementary is a elementary school in Ontario, California, part of Ontario-Montclair Schools. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for Elderberry Elementary are almost always made at the district level. If Ontario-Montclair Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Ontario-Montclair Schools forecast).
Urban districts usually have the best-treated roads and the shortest bus routes, so they tend to hold out longer before closing — but they also weigh sidewalk conditions and transit reliability for students who walk or ride public transport.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with Ontario-Montclair Schools before acting on it.
