When falling rain comes into contact with a freezing cold surface the rain turns into ice on contact. Extreme air pressure is created at an atmospheric level as warm wet air rushes, causing cold air to move towards the area where air pressure is lower, eventually creating a rotation. They pass through the cold air just above the surface. It starts as snow and turns to rain as it hits a layer of warm air.
