It is still very difficult to predict and is surprisingly hard to measure once it has fallen. Based on National Weather Service records for 1961 through 1990, Rochester, New York averages 94 inches of snow annually and is the snowiest large city in the United States. Buffalo, New York, is a close runner-up in terms of U.S. large cities with the most snow. Each year an average of 105 snow-producing storms affect the continental United States. A typical storm will have a snow-producing lifetime of two to five days and will bring snow to portions of several states.
Fresh snow is an excellent insulator.
Practically every location in the United States has seen snowfall. Even most portions of southern Florida have seen a few snow flurries. Snow kills hundreds of people in the United States each year. The primary snow-related deaths are from traffic accidents, overexertion, and exposure, but deaths from avalanches have been steadily increasing. The greatest snowfall officially reported at the Phoenix, Arizona National Weather Service Office was one inch.
