Powered by NOAA / National Weather ServiceOakland Mills High is a high school in Columbia, Maryland, part of Howard County Public 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 Oakland Mills High are almost always made at the district level. If Howard County Public Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Howard County Public 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.
High schools start earliest, so they feel a storm before the rest of the district does — the first buses often roll while roads are still being treated. That earlier start time is one reason a district watching a morning storm may call the day off entirely rather than run a delay.
Maryland averages about 21 inches of snow per year. Maryland districts split between Baltimore-area and DC-area patterns. Western Maryland mountain districts have much higher closure thresholds.
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 Howard County Public Schools before acting on it.
