Precipitation often starts in clouds as snow. If the precipitation falls through air that is above freezing temperature, it hits the ground as:
Rain
Sleet
Snow
Hail
This type of precipitation starts in the cloud as snow and only passes through air that is below freezing temperature. It hits the ground as:
Rain
Sleet
Snow
Hail
This type of precipitation starts off as snow in the cloud. When it falls from the cloud, it first goes through a layer of warm air that melts it. If there is a layer of freezing air before it hits the ground, it freezes into tiny balls of ice.
Rain
Sleet
Snow
Hail
This type of precipitation starts in the cloud as small ice pieces. They fall from the cloud only when they are heavy enough, usually as large ice stones.
