Powered by NOAA / National Weather ServiceJoseph Arthur Middle School is a middle school in O Fallon, Illinois, part of Central SD 104 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 Joseph Arthur Middle School are almost always made at the district level. If Central SD 104 Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Central SD 104 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.
Illinois averages about 38 inches of snow per year. Chicago Public Schools rarely close, but suburban and downstate districts close more frequently for lake-effect and prairie blizzard events.
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 SD 104 Schools before acting on it.
