Snow squalls are brief, heavy snow showers.

Erica's Answer:

They usually form in a long line with a mostly south-north orientation, but they can have an east-west orientation. Snow squalls form in a similar way as thunderstorms in the summer. The squall develops because of a burst of energy moving through a moist, cold atmosphere. The burst of energy provides the "spark" necessary to form the snow squall. Snow squalls tend to move rapidly, instead of remaining over the same area.
