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.

We are in the process of quality controlling past data, so some of these values are subject to change. Additionally, some observers do not report daily, so data may be missing at times. To view the observations, hover over a location on the left and choose the desired tab along the top of the page.
