Powered by NOAA / National Weather ServiceRuth Musser Middle is a middle school in Rancho Cucamonga, California, part of Central Elementary 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 Ruth Musser Middle are almost always made at the district level. If Central Elementary Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Central Elementary Schools forecast).
Suburban districts depend heavily on bus fleets covering a wide area of residential streets, which are plowed after main roads. Side-street conditions at 5 AM often decide the call.
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 Central Elementary Schools before acting on it.
