All weather forecasting companies have access to the same data basic. The differences between the final forecasts are due to how each company interprets and adjusts the data they receive from weather models.

The weather forecasts on OpenSnow are updated every hour with a proprietary blend of global weather model data from the GFS (American), GDPS (Canadian), and ICON (German) weather models, along with high-resolution weather model data from the HRRR (American) and HRDPS (Canadian) weather models.

The benefits of this approach include:

  • Proprietary algorithm to improve the snow-to-liquid ratio, precipitation, temperature, and wind speed calculations for cold, mountain environments.
  • Provides the ability to create a forecast for any location (and elevation) to ensure that we are forecasting conditions on the mountain and not for a nearby town.
  • An improved method for calculating the snow level (elevation that separates rain from snow) to provide a more realistic forecast, especially at the beginning of storms and during times of intense snowfall.
  • Blending multiple global and high-resolution models increases accuracy and confidence in the forecast.

The weather forecast data on OpenSnow can be viewed as hourly forecasts for the next 10 days and day/night forecasts for the next 10 days.
