Recent and Current Conditions
Wyoming experienced its 23rd coolest and 45th wettest April out of 128 years, according to National Oceanic and Atmospheric Administration’s (NOAA) National Centers for Environmental Information (NCEI) database, retrieved May 23. Scaling to the county level – the adjacent tables show temperature and precipitation rankings of select counties for the month of April.
The U.S. Drought Monitor (USDM) map for Wyoming, released May 19, shows 100 percent of Wyoming continues to experience abnormally dry conditions (D0) – or moderate to extreme drought (D1 – D3). This is the 36th consecutive week all of Wyoming is in a “D” category.
