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.
The difference between sleet and hail are? sleet is actually water when its in the clouds and it freezes on its way down. Hail is frozen already in the clouds and actually gets warmer on its way down but still is ice. â¦
