RELATED: What is a snow squall?

A snow squall may only produce a small amount of snow accumulation because it is fast, short-lived and often happens without a larger and longer winter storm. But that doesn't mean it isn't dangerous.

A snow squall moves in very quickly, often interrupting an otherwise clear day, and creates sudden whiteout conditions. That, coupled with plunging temperatures, leads to icy streets and highways in minutes. Many motorists are subsequently caught off-guard.
