How school closure decisions work in Missouri
School districts in Missouri consider multiple factors when deciding whether to close, delay, or hold classes on a snow day. Beyond raw snowfall totals, superintendents evaluate ice accumulation on roads and sidewalks, wind chill temperatures that affect students waiting at bus stops, the timing of the storm relative to morning and afternoon commutes, and whether road crews have had enough time to clear primary bus routes.
Most districts make their announcements between 5 AM and 6 AM on the day of the event, though some issue closures the evening before when a major storm is certain. Public school decisions are typically made at the district level, while private and charter schools often decide independently. Two-hour delays are common when conditions are expected to improve by mid-morning.
