List of Minnesota weather records

The following is a list of Minnesota weather records observed at various stations across the state during the Over 160 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 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 late 19th century and early 20th century most statewide stations that exist today were in operation.^[1][2]
