The 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, lightning, 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 data can be viewed as hourly forecasts for the next 5 days or daily forecasts for the next 10 days and includes:

  • Day & Night Snow Forecast
  • Day & Night Snow Level
  • Daily High & Low Temperature
  • Hourly Chance of Precipitation
  • Hourly Temperature
  • Hourly Lightning Potential
  • Hourly Wind Speed, Gust, & Direction
  • Hourly Cloud Cover %

The forecast data is updated every hour on OpenSnow for any location, worldwide.
