Eight to 14-day, one-month and grass-cast forecasts
NOAA’s eight to 14-day forecast for July 1-7, made June 23, is leaning towards below-normal temperatures for the western half of Wyoming with a 33 to 40 percent probability or chance. For the eastern edge of the state, it is leaning slightly towards above-normaltemperatures with a 33 percent probability.
For areas in between, there are equal chances for above, near orbelow normal temperatures.
Over the same timeframe, there is a 33 to 40 percent chance of above-normalprecipitation for the majority of Wyoming. An exception is the southern portion of Sweetwater County, into western Carbon County, which has equal chances for above, near or below normalprecipitation.
The July forecast for Wyoming, made June 18, indicates a 50 percent probability of above normaltemperatures throughout the state and a 33 to 40 percent probability of below normalprecipitation.

The latest grass-cast maps, made June 16, suggest, for portions of eastern and central Wyoming, if these areas receive above normalprecipitation between now and Aug. 31, they should still expect five to 30 percent lesspounds per acre of rangeland vegetationcompared to a 38-year average.
If these areas instead receive nearor below normalprecipitation for the rest of the growing season, then production could be reduced by 30 percent compared to the 38-year average, if not worse.
