Everything you need to know about our snow day predictions
Enter your 5-digit ZIP code and select your school type. We pull tomorrow's weather forecast for your area and calculate a snow day probability based on snowfall, temperature, wind, and precipitation.
We support public schools, private schools, and colleges/universities. Each has a slightly different threshold for closure based on historical patterns.
A 0% chance simply means tomorrow's forecast shows no significant winter weather — clear skies, warm temperatures, or light precipitation that wouldn't cause a closure.
