What are the main causes of blizzards?

What causes a Blizzard? In general blizzards occur when a mass of warmer air collides with a mass of very cold air. The cold air mass cuts under the warm air mass and as the warm moist air rises upwards it forms snow. The collision of the air masses also provides the atmospheric tension required for high wind speeds.
