That brings us to something most people don't know about blizzards. It's important--it's the key to getting some good from a blizzard. As those tiny ice grains go flying by, they're shrinking--evaporating! Hard to believe? We can't see it happen, can't feel it, but we can measure it with instruments. Even when it's way below cool, and dark-thirty at night, the farther those ice grains blow, the smaller they become.
So how is evaporation the key to managing a blizzard? First, if there's a limit to how far snow blows before it's vaporized, then we've got a chance to build something big enough to catch what comes. Seems like the stuff blows from forever (from Utah to Nebraska, as we say in Wyoming) but that's not so--really! Second, if you can keep it from blowing, not much evaporates, and you can save yourself some water--a lot of water. There are more blizzard basics, but knowing that snow evaporates is the key to blowing snow management.
