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.
