Four types of winter precipitation. While all forms of precipitation start as snow high up in the clouds, there are four primary types that eventually reach the ground: snow, sleet, freezing rain and plain ol' rain. Snow occurs when the atmosphere is cold all the way from the clouds to down here at the surface.
What are snow ratios? The snow to liquid ratio is a way of describing what makes light, fluffy snow different from heavy, wet snow. The temperature can have a huge impact on the amount of snow as well as how much it weighs. The snow ratio compares the amount of liquid precipitation with the number of inches of snow. In colder weather, snow has more air space so there are more inches of snow. Wet snow that falls at the freezing mark is usually sloppy and heavy.
