Location > Snow Forecast Summary
We calculate the snow forecast summary by taking the snow forecast for the previous night plus the current day. The following snow forecast summary example has 8 inches for Friday...
- Thursday Night = 2-4 inches = 3 inches
- Friday Day = 3-7 inches = 5 inches
- Friday Summary = 8 inches
As seen in the image at the top of the article, this would make Friday orange since the snow forecast is above 6 inches. The snow forecast summary calculation is shown this way since this is the snow that you would see/ski on that day.
