How do Blizzards form?

A blizzard starts when are two different air masses that have different temperatures. When they both collide into each other it is cold air to warm air, this is also called a front. When the cold air advances and goes through the warm air it is a cold front.

When the warm air goes through the cold air it is called a warm front. When both of them are stuck and wont move it is called a stationary front. These cause a lot of different types of storms when it is stationary.

The way this creates a blizzard is when the cold air goes under the warm air and the warm air rises. This will make it really cold on the ground and warmer in the air. Another thing that is needed to cause a blizzard is it to be really moist out. When these are in one combination there are chances of having a blizzard.
