How Are Blizzards Produced?
When a polar air mass and a warm air mass meet
the cold air pushes the warm air up into the
atmosphere.
As the warm air mass stays in the atmosphere the
water vapor forms into snow clouds.

When the low temperatures mix with the winds and
the snow they create a blizzard!
