The combination of heavy rain and anomalously warm temperatures melting a deeper than average snowpack during April resulted in moderate to major flooding at sites along the Upper Mississippi River in Minnesota. Initial minor flood stage was reached in mid April with near record crests towards the end of April. Drier conditions during the latter half of April and well below normal rainfall through May allowed the Upper Mississippi River to steadily recede, dropping below minor flood stage at sites in Minnesota during the beginning of May.
