Fog develop across southeast Minnesota and reduced the visibility to less than mile for an extended period starting on the 29th and continuing through much of the 30th. One person was killed in a car accident on U.S. Highway 63 in Mower County. During this period, an extended period of dense fog with visibilities of a quarter mile or less occurred. A brief period of freezing drizzle also occurred during the late afternoon of the 31st creating a glaze of ice on exposed surfaces. As an area of low pressure moved across the Midwest, warm air spread over the region and caused the deep snow pack to begin melting which resulted in the formation of the fog.
