List of Minnesota weather records
Weather observations being taken in Minneapolis, Minnesota in 1890.
The following is a list of Minnesota weather records observed at various stations across the state during the last 130 years. Minnesota is a state in the Upper Midwestern region of the United States. Due to its location in the northern plains of the United States its climate is one of extremes. Minnesota's history of nearly continuous meteorological record keeping stretches back nearly two centuries to 1819 when Fort Snelling was settled. By 1871 the first official government observations were taking place in the Twin Cities and by the early 20th century most statewide stations that exist today were in operation.[1][2]
