Eagerly watching the forecast? Our Snow Day Calculator analyzes weather conditions and school factors to estimate the probability of a snow day. Enter the expected snowfall, temperature, and other conditions to see if you'll be building snowmen instead of doing homework!
School closures depend on multiple factors: snowfall accumulation, temperature, wind speed, storm timing, and your school district's history. Northern areas with better snow removal equipment typically need more snow to close, while southern districts may close with just a few inches. Our algorithm weights each factor to provide a realistic probability estimate.
Probability Formula
P(Snow Day) = f(Snowfall, Temp, Wind, Timing, School Type)Know whether to prepare for a potential day off or normal school routine.

This provides an estimate based on typical school closure patterns. Actual decisions depend on your specific district's policies, road conditions, and superintendent judgment. Use it as a fun guide, not a guarantee!
Different schools have different closure thresholds. Rural schools with long bus routes may close earlier. Urban schools with walking students may stay open longer. Private schools often follow their own criteria.
Schools with limited snow days remaining may be more conservative about calling closures. If your district has used most of its allotted snow days, they may opt for delays or virtual learning instead.
Overnight storms give crews time to clear roads before morning buses. Morning storms during commute time are most likely to cause closures. Afternoon storms may lead to early dismissal rather than full closure.
Yes! Areas that don't regularly experience snow have less equipment and experience handling it. A few inches in Georgia might close schools, while the same amount in Minnesota barely causes a delay.
