The polar vortex can be a powerful source of winter weather, but it's not the only cause of severe cold and snow in regions better known for warmth and sunshine.

The polar vortex is within the stratosphere. Because of the lack of sunlight, both the Earth's poles have substantially cooler temperatures than the equator.

On Monday, the polar vortex will reach the Deep South, with temperatures down to the freezing point of 32 degrees Fahrenheit in Atlanta. Wind chills will be in the 20s.
