About this forecast
Alta is a ski resort in Utah with a base at 8,530 ft and a summit at 10,550 ft, 2,020 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.
Other ski resorts in Utah
Base: NOAA's forecast for the base area (forecast grid elevation 9,800 ft). Summit: estimated from the base forecast with typical cooling by elevation; on calm, clear nights cold air can pool at the base instead.
