The following graphics show year-to-date observations for temperatures, precipitation, and snowfall for each day of the year and each month at several observing sites across western South Dakota and northeastern Wyoming.
Many of these sites are maintained by cooperative observers, a program which you can learn more about here.

To view the observations, hover over a location on the left and choose the desired tab along the top of the page.
