This "Day in Weather History" contains some memorable weather events and trivia from 1805 to the present day for much of Minnesota and west central Wisconsin. Many sources were used to research and compile the data. The Twin Cities/Chanhassen National Weather Service would especially like to thank the Minnesota State Climatology Office and its contributors for their input into this database.
