How does a blizzard form?

This is a very powerful Blizzard

To form this terrible weather, it needs three things: 1^st, Cold air. You need this to make snow. 2^nd, lots of moisture. You need this to make clouds. Finally, warm air. The warm air needs to go on top of cold air. This creates a front. It makes a large snowstorm, also known as a blizzard. If you have more of the blizzard ingredients, the more powerful the storm is.
