Wyoming’s overall average November temperature (30.6°F) was near the 1900-2000 average for the state. Similarly, the state received an average of 1.05 inches of precipitation in November, which was also near the average for the last century. 

            The adjacent tables highlight minimum and maximum temperatures and precipitation rankings and anomalies, compared to the last century, for select counties, for the month of November.

            The U.S. Drought Monitor (USDM) map for Wyoming, from Dec. 31, indicates that abnormally dry conditions persisted in Carbon, Sweetwater, Uinta and Lincoln counties since Nov. 26. Abnormally dry conditions expanded their footprint in Lincoln County and into Teton, Park, Fremont and Sublette counties. 

            In total, 24.87 percent of the state is abnormally dry. View the current USDM maps at You can help inform the USDM by submitting conditions and impacts at

            The snow water equivalent (SWE) throughout Wyoming ranges from 66 – 149% of normal according to the January 7 USDA Natural Resource Conservation Snow Telemetry Service (SNOTEL) report. The two areas with the lowest SWE are the southern portion of Fremont County just north of the Great Divide Basin, 66 percent, and the northwest corner of Yellowstone National Park 82 percent.

There is a 33-40 percent probability for above normal precipitation throughout the entire state for the same timeframe.

The exception is the eastern third of the state where there is an equal chance for below, near or above normal temperatures. For the same timeframe, there is a 33-40 percent probability for above normal precipitation for the northern half of the state. To view NOAA’s most recent forecasts, visit
