Our goal is to create the most accurate weather forecast, period. 

The weather forecasts in OpenSnow are created by our proprietary PEAKS model, producing forecasts up to 50% more accurate in mountain terrain.

PEAKS learns from past storms and transforms normal weather models (used by other apps) into sharper, more location-specific forecasts. Learning from past storms is what human meteorologists do, but unlike humans, PEAKS can forecast for every location on Earth and provide updates within a few seconds.

The benefits of PEAKS also 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.

The weather forecast data on OpenSnow can be viewed as hourly and daily forecasts for the next 15 days

Hourly:

  • Snow Forecast
  • Snow Ratio
  • Snow Level (Rain/Snow Elevation)
  • Precipitation Chance
  • Precipitation Forecast
  • Temperature
  • Feels Like Temperature
  • Relative Humidity
  • Wind Direction, Speed, & Gust
  • Cloud Cover
  • Lightning Potential

Day & Night:

  • Snow Forecast
  • Snow Ratio
  • Snow Level (Rain/Snow Elevation)
  • Precipitation Chance
  • Precipitation Forecast
  • Temperature
  • Feels Like Temperature
  • Relative Humidity
  • Wind Direction, Speed, & Gust
  • Cloud Cover
  • Weather Alerts
Daily alerts are also included to signal upcoming powder days, along with the potential for rain, snow/rain, and high winds. Alert breakdown:

  • Orange = Powder (Forecast of 6+ inches from the previous night and current day)
  • Green = Rain (Expect rain on all of the mountain)
  • Purple = Snow/Rain (Expect a transition from snow to rain on the mountain)
  • Yellow = Wind (Wind gusts greater than 45 mph and possible lift closures)
