Visiting a school recently, a young girl asked, do we ever have "snowbows"? They are highly unlikely. Rainbows are formed when light hits water droplets and scatter into all the colors of the rainbow. ROY G BIV. A water droplet acts like a prism. The sun has to be low in the sky, close to setting or a few hours after sunrise. You'll never see a rainbow when the sun is high in the sky. It's always when the sun is on one side of you, and a rain cloud, or mist is on the other side of you. Snow consists of ice crystals, they bounce, and scatter the light differently than raindrops will.
