Factors to Consider when Closing Schools on Snowy Days:

Superintendents usually consider these before 5 A.M.:

1. Timing of the Storm: Heavy snow during the morning, like 5 AM - 8 AM is the common reason for a school closure. Schools are less likely to close if an overnight storm ends by 3 a.m. because that’s easier for road construction crews to manage.
2. Freezing Rain: This is a dangerous situation, as a thin layer of ice is more dangerous than several inches of snow because it makes roads slippery for buses, cars and pedestrians.
3. Wind and Visibility: Heavy snowfall and strong winds make travel unsafe, no matter how clear the roads are. This is a major factor in rural and open areas.
4. Extreme Cold: In the coldest areas, schools may close if the air temperature drops below -40° F/C, as children waiting for the bus could be at risk of frostbite.

The Rise of Remote Learning:

Since 2020, many school have replaced traditional snow days with remote learning days. Instead of getting a day off, students log on from home.

Accuracy:

Our snow day predictions are based on the OpenWeatherMap data source, which provides temperature, snowfall, wind speed and historical data. We strive for accuracy, but our estimates should be used as a guide rather than a guarantee.

This snow day calculator provides estimates based on historical data and current weather conditions. The final decision for school closures always rests with school administrators and local authorities.
