How Missouri Schools Handle Snow Days

Superintendents consult with road crews, transportation supervisors, and the National Weather Service before announcing closures, two-hour delays, or remote-learning days.

Closures are communicated through district websites, automated phone calls, local TV and radio stations, and increasingly through social media and parent alert apps.
