Powered by NOAA / National Weather ServiceGateway Science Academy High is a high school in St. Louis, Missouri, part of Gateway Science Acad/St Louis 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 Gateway Science Academy High are almost always made at the district level. If Gateway Science Acad/St Louis Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Gateway Science Acad/St Louis 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.
Missouri averages about 20 inches of snow per year. St. Louis and Kansas City areas close at different thresholds. Ice storms along the I-44 corridor are a frequent closure trigger.
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 Gateway Science Acad/St Louis Schools before acting on it.
