Recent and current conditions

by Wyoming Livestock Roundup

The August average temperature (65.1°F) and precipitation (0.93”) for Wyoming ranked 97th and 58th, respectively, of 125 years data have been collected. Taking a closer look, the adjacent diagrams highlight notable average minimum and maximum temperatures and precipitation for August and more broadly for the season – for select counties.

            Also of interest, the August average minimum temperature anomaly for all Wyoming counties were at least 0.4 degrees (Natrona County) warmer than the 1901-2000 average.

            Similarly, the seasonal average minimum temperature anomaly, for all counties, were at least 0.01 degrees (Natrona, Fremont and Sublette counties) or warmer except Hot Springs (0.0 degrees) and Washakie counties – the latter was 0.2 degrees cooler than the 1901-2000 average.

            The U.S. Drought Monitor (USDM) map for Wyoming, from Sept.17, indicates that abnormally dryconditions are persisting in Sweetwater, Uinta, Lincoln and Laramie counties – and these conditions have expanded into southern Albany, Carbon, western Fremont and much of Sublette county since Aug.13.
