Calculate your chance of having a snow day based on the number of inches of accumulated snow and your state of occupancy.

How to calculate the chances of having a snowday?
The chances of school being canceled by snow is a complex question to ask. There are several factors that go into this equation.
- The amount of snowfall is the number one driving factor. The more snow falls, the greater chance of a snow day.
- The next factor is how ready your area or state is to deal with snow. The more northern a state is located the more often they will see snow. In turn, this leads to northern states being more prepared for snow and vise versa for southern states.
- Another factor that determines your chance of a snow day is whether the snow storm is bringing any ice along with it. Ice is extremely difficult to deal with on roads. In turn, if a storm is bringing ice with it, the chances of a snow day go way up.
- One last factor that will effect your chance of a snow day is the predicted temperature the following day of the storm. Sometimes you can have a huge snow storm but then the temperature warms up. This will cause the snow to melt and make it easier to drive on.
Will i have a snow day?
Your chances of having a snow day are mostly dependent on where you live. This is because states that see a lot of snow are more prepared to deal with it. For instance, in a state like Maine, it may take up to 12″ or more just to cancel schools. They see big snow storms every year and are prepared with trucks and salt to keep the road ways clear.
A state like South Carolina is the opposite. They rarely see snow, and as a result they don’t have barely any equipment to deal with it. When they see even an inch of snow it can shut down highways completely. This means that even a trace amount of snow will cancel schools.
This calculator takes the average amount of snow it takes to cancel schools in a given state and converts it to a percent, but that does now mean it will be the same for every county in the state.
For example, in New Jersey, the northern end of the state sees anywhere from 2 to 3 times more snow than the very southern part of the state. Because of this, Northern New Jersey is much more prepared for snow, and it may take anywhere close to 8″ to cancel schools while it my only take 3-4″ in southern New Jersey to cancel schools. The same goes for eastern and western PA.
