Record cloudiness in January set the stage for a mild winter, but then heavy snows fell in April. Tropical Depression Cristobal caused mudslides in southeastern areas of Minnesota, and was the state's first known direct encounter with a tropical cyclone.
A tornado near Dalton, Minn., was the most violent since 2010. Damaging winds and hailstorms struck repeatedly during late summer. A massive downpour hit parts of eight counties with at least six inches of rain.
Record October snows and cold were followed by temperatures climbing from the single digits to the 70s and 80s in many areas between Oct. 27 and Nov. 4. A combination of the snow and high winds on Dec. 23 brought blizzard warnings in 70 of the state's 87 counties.
