The University of Minnesota's Department of Soil, Water, and Climate maintains a Climatological Observatory on the grounds of the University's St. Paul campus. This page provides links to charts that show the last 3 days of data collected at the Observatory. These charts are updated each hour. The new charts should be available by about 15 minutes after the top of the hour.
Some charts show average values for the hour.
Precipitation and evaporation charts show the total for the hour. Data are sampled every five seconds to build the hourly summaries. Labeling on the X-axis of most of the charts is of the form MM DD HOUR, showing the month, day, and hour for the data. The time is Central Standard Time. Wind Max., Avg., and Min.
