(Q) How do you calculate the snow forecast summary?
We calculate the snow forecast summary by taking the snow forecast for the previous night + the current day. The summary calculation is shown this way since this is the snow that you would see/ski on that day.
Example: The snow forecast summary has 12 inches for Friday.
- Thursday Night = 5-9 inches = 7 inches
- Friday Day = 3-7 inches = 5 inches
Friday Summary = 12 inches
(Q) How do you make your forecasts?
The forecasts on OpenSnow are updated every hour with a proprietary blend of global data from the GFS (American), GDPS (Canadian), and ICON (German) weather models, along with high-resolution data from the HRRR (American) and HRDPS (Canadian) weather models.
- 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.

- 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)
(Q) What is the difference between the blue and orange snow forecast bars?
Blue bars show snowfall under 6 inches. Orange bars show snowfall over 6 inches. The color change is simply a visual clue to denote the higher snow totals and deeper powder.
(Q) How do you break up the day and night 10-day forecast?
The "day" forecast is from 6 AM to 6 PM, while the "night" forecast is from 6 PM to 6 AM.
