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

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

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

This blend of proprietary forecast data is updated every hour on OpenSnow for any location, worldwide.

Here is an example of the OpenSnow 10-day snow forecast for Winter Park, Colorado:

  • Blue bars show snowfall under 6 inches.
  • Orange bars show snowfall over 6 inches.
  • Purple bars indicate mixed precip (rain/snow).
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)
