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

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 5 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:

• Weather Alerts
• 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

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 Alyeska, Alaska:

• 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)
