Lot of people are discussing temperature and humidity as if those were the only things that matter. Surprised no one's posted the chart.
Still, many times we've seen K3000 make snow when the chart says you can't. When you absolutely positively gotta have it, that is still Killington's go to gun. Way back when I was a wet behind the ears engineer I worked with cryostats. We used bottles of liquid nitrogen to cool an infrared detector down near absolute zero. It gives you a healthy appreciation for what the expansion of compressed air can do. Right now Killington has a ton of air, idle compressors, and no snow. You tell me what you think they'll do. Snow making this weekend isn't impossible, just expensive. The louder the gun, the more money its burning. What will work against Killington is the temperature of the water in the snow making ponds: probably pretty warm. Still, much of the energy removal is in the state change from liquid to frozen at 32F.
