The July 2017 climate summaries for Big Piney, Buffalo, Casper, Greybull, Lake Yellowstone, Lander, Riverton, Rock Springs, and Worland are now available online.

July 2017 was drier than normal, but was certainly wetter than July 2016. Last year, several locations only recorded a trace of precipitation for the month of July. Only a handful of sites had above normal precipitation, with Buffalo receiving almost 1.5". Despite these low totals, the area has not had many wildfires so far (thankfully). Hopefully, this will continue into August. The lack of fire activity could be partially attributed to temperatures. Although most sites were only +2.0 to +3.0 degrees above average, the region has not experienced an oppressive heat wave. In fact, the area enjoyed a plume of monsoonal moisture by the middle of the month and lasted toward the end of the month. See the links below for details for individual sites or click here for Water Year Precipitation summaries for more locations.
