A live wet-bulb check. Can snowmakers run where you are, and when?

How this works
We pull NOAA's hourly forecast for your location and calculate the wet-bulb temperature for each hour. Snowmakers rely on wet-bulb because it accounts for both cold and dry air, the two conditions that let water droplets freeze in flight. Below 28°F−2°C they can run; below 25°F−4°C the snow is good quality.

About this forecast

Granite Peak is a ski resort in Wisconsin with a base at 1,200 ft and a summit at 1,900 ft, 700 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 1,247 ft). Summit: estimated from the base forecast with typical cooling by elevation; on calm, clear nights cold air can pool at the base instead.
