About this forecast
Grand Targhee is a ski resort in Wyoming with a base at 7,851 ft and a summit at 10,230 ft, 2,379 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.

Base: NOAA's forecast for the base area (forecast grid elevation 9,062 ft). Summit: estimated from the base forecast with typical cooling by elevation; on calm, clear nights cold air can pool at the base instead.
