(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 automated forecasts on OpenSnow are updated multiple times per day with a proprietary blend of data from the GFS (American), GDPS (Canadian), and ECMWF (European) weather models. The benefits of this approach include:

  • Blending multiple global models increases accuracy and confidence in the forecast.
  • Hourly data for any location in the world.
  • Proprietary snow-to-liquid calculation to improve accuracy, especially in colder environments.
  • 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.
  • 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.

We also plan to add even more global and high-resolution models into our proprietary forecast blend over time. Our goal is to create the most accurate snow forecast and we're just getting started.

(Q) What do the different colored alerts signal?

Daily alerts are included to signal upcoming powder days, along with the potential for rain, snow/rain, and high winds. Alert breakdown:

  • Blue = 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)

(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.
