You can use these calculators to calculate snow days, load, drift, probability, and more..

**Snow Day Calculator
**

Using a carefully developed formula, the Snow Day Calculator will predict snow days or delays for school using just your zip code.

**Snow Load Calculator
**

Calculate snow load.

**Snow drift loading
**

Snow drift loading - adjacent to roof obstructions

**Snow probability calculator
**

The calculator calculates the melting temperature associated with the given relative humidity. Below this temperature, snow cannot melt because of evaporation. At higher temperatures, it may snow, with a decreasing probability.

**Snowfall To Rainfall Calculator
**

This calculator is designed to approximate the conversion of snowfall amounts to rainfall amounts. This calculation is particularly useful when trying to determine the amount of water added eventually to aquafers or lakes in the area.
