About this forecast
Sierra-at-Tahoe is a ski resort in California with a base at 6,640 ft and a summit at 8,852 ft, 2,212 ft of vertical. This page checks NOAA's hourly forecast at the base and the summit every time you load it and works out the wet-bulb temperature, which is what decides whether snow guns can run. Snowmakers can start below 28°F−2°C wet-bulb, and make good snow below 25°F−4°C.
