A severe winter storm is a prolonged storm event in which the varieties of precipitation are formed that only occur at low temperatures, such as snow or sleet, or a rainstorm where ground temperatures are low enough to allow ice to form (i.e. freezing rain). The characteristics of severe winter storms are determined by the amount and extent of snow or ice, air temperature, wind, and event duration (National Weather Service, 2009). The common types of winter precipitation are snow, sleet, and freezing rain.
