The National Weather Service Volunteer Cooperative Network began in 1890 and historically consists of approximately 175 active stations in a given year in Minnesota. The 2016 Waseca precipitation record is the highest in over 20,000 statewide annual precipitation totals over the past 125 years.
The wet conditions led to other stations breaking their own all-time annual precipitation records, especially in the southern portions of Minnesota. Below are the annual records set in 2016 for stations having at least 75 years of precipitation observations.
