The climate of Minnesota is typical of a continental climate, with cold winters and hot summers. Minnesota's location in the Upper Midwest allows it to experience some of the widest variety of weather in the United States. Winter in Minnesota is characterized by cold temperatures as low as −60 °F (−51 °C). Snow is the main form of winter precipitation, but freezing rain, ice, sleet, and occasionally rain are all possible during the winter months. Common storm systems include Alberta clippers or Panhandle hooks, some of which evolve into blizzards. Annual snowfall extremes have ranged from over 170 inches (432 cm) in the rugged Superior Highlands of the North Shore to as little as 10 inches (25 cm) in southern Minnesota. Spring is a time of major transition; snowstorms are common early, but by late spring as temperatures begin to moderate the state experiences tornadoes, averaging 24 per year. In summer, humid conditions help kick off thunderstorm activity 30–40 days per year. Summer high temperatures as hot as 114 °F (46 °C) are possible. Autumn weather in Minnesota is largely the reverse of spring weather; the jet stream—which tends to weaken in summer—begins to re-strengthen, leading to a quicker changing of weather patterns and an increased variability of temperatures. By late October and November these storm systems become strong enough to form major winter storms. (more...)
