Blizzard Aftermath A snow blizzard that struck the East Coast of the United States in January 1996, left the Boston area with about 46 cm (about 18 in) of snow. A snowstorm is called a blizzard when visibility is less than 0.40 km (0.25 mi) and the snowfall is accompanied by strong winds.

Weather, state of the atmosphere at a particular time and place. The elements of weather include temperature, humidity, cloudiness, precipitation, wind, and pressure. These elements are organized into various weather systems, such as monsoons, areas of high and low pressure, thunderstorms, and tornadoes. All weather systems have well-defined cycles and structural features and are governed by the laws of heat and motion. These conditions are studied in meteorology, the science of weather and weather forecasting.

Weather differs from climate, which is the weather that a particular region experiences over a long period of time. Climate includes the averages and variations of all weather elements.
