Answer 1

Blizzards form when cold air masses meet warm, moist air masses. The warm air rises above the cold air, cools down, and forms snow clouds. As these clouds move, they drop heavy snowfall, strong winds, and low visibility, creating blizzard conditions. So, even though blizzards involve cold air, they still need some warm, moist air to start the process.
