Powered by NOAA / National Weather ServiceJohn Weldon Elem. is a elementary school in Dardenne Prairie, Missouri, part of Francis Howell R-III 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 John Weldon Elem. are almost always made at the district level. If Francis Howell R-III Schools closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Francis Howell R-III 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.
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 Francis Howell R-III Schools before acting on it.
