Will School Close?

SnowDayCalculator PLUS isn't just a weather app; it's a specialized school closing prediction engine. We utilize advanced real-time meteorological data analysis to process feeds directly from the National Weather Service (NWS) and NOAA.

Our algorithm goes beyond simple snowfall totals. We analyze a matrix of critical factors that superintendents use to make their decisions:

• Timing of Precipitation: Snow starting at 5 AM is far more likely to cause a closing than snow starting at 10 AM.
• Temperature Drop Rates: Rapid freezes that create "black ice" on rural roads are a major safety hazard.
• Wind Chill & Visibility: Extreme cold that makes waiting for the bus dangerous, or whiteout conditions that affect driver safety.

By combining these atmospheric data points with historical closure trends for your specific region, we generate a probability score that tells you the true likelihood of a snow day.

Have you ever wondered why school stays open during a storm, or closes when there's barely any snow? The decision is complex and involves more than just looking out the window.

The "Bus Safety" Criterion

The number one priority for any school district is student safety, specifically regarding bus transportation. Superintendents consult with road crews and police as early as 3:00 AM. If rural roads (which are plowed last) are deemed unsafe for heavy school buses, the entire district often closes, even if the main town roads are clear. This is why our "Rural" school type setting increases the sensitivity of our prediction model.

Public vs. Private Schools

Public schools often have a larger transportation footprint and stricter liability concerns, making them more likely to close. Private schools may have different thresholds or start times. Our calculator allows you to toggle between these modes to get a prediction tailored to your institution type.
