Where do snow storms come from?

In North America, Winter Storms often happen when a cold and dry air mass or Cold Front, moves down from Canada and collides with a warmer and humid air mass or Warm Front, from the Gulf of Mexico. In the Southern United States the boundary between the two air masses produces precipitation that falls as rain.
