Winter Weather Lesson Plan
Blizzards are winter storms with very low temperatures and high winds that blow at least 35 miles per hour. The air temperature is usually around 20 degrees Fahrenheit. Severe blizzards are not very common, but when they do, the air temperature can be colder than 20 degrees Fahrenheit. The wind blows snow hard and it gathers in tall drifts. The snow often piles up against houses and cars. Sometimes the snow is so deep that it can bury large objects like trains, cars, and sometimes houses.
			Blizzards happen most often on the north great plains, but South Dakota is known as the "blizzard state". Blizzards have occured as far south as the state of Texas.
			This photograph was taken after an entire winter of blizzards had passed. The snow here is estimated to be between 25-30 feet deep.
