Most communities in Washington have Good air quality. Several communities along the eastern edge of Washington from Spokane south to Clarkston have Moderate air quality. Some areas in Yakima county also have Moderate air quality. The area of biggest concern is the Wenatchee-Leavenworth area where smoke from the Eagle fire has produced Unhealthy for Sensitive Groups air quality.

SMOKE DISPERSION FORECAST:
Wildfire smoke dispersion depends on the stability of the atmosphere and wind speed. A stable atmosphere reduces the height that a plume will reach and will tend to trap smoke near the ground. Unstable atmospheres, created by either sunlight warming the ground or moderate wind speeds, rapidly disperse smoke.
The low, currently over northwestern California, will track northeasterly to cross the Central Washington Cascades Friday morning. In the process, it will open up and lose much of its strength, producing only light amounts of precipitation. The Haines Index, values greater than four indicate strong convection and possible lightning, drops below three Thursday evening and remains there through the weekend. The Leavenworth area should see some light precipitation early Friday morning and temperatures should be as much as ten degrees cooler. Friday morning southwest winds should begin moving smoke northeastward across the Columbia Basin and push away any that intruded from wildfires in Idaho.
Winds along the Columbia are predicted to be westerly and should keep smoke from the Government Flats Complex away from Southern Washington.
An upper level trough will move in closer to the state from off the coast over the weekend and early next week bringing cooler temperatures and more clouds. Sufficient precipitation is forecasted on Friday and again on Tuesday to reduce the likelihood of additional fire starts from lightning.
That precipitation should also reduce the amount of smoke. Most areas of the state should return to Good air quality. Leavenworth may continue to have Moderate air quality because of smoke from the nearby Eagle fire.

(Seattle—August 7,2013) The U.S. Environmental Protection Agency has lifted the burn ban on all outdoor burning on the Yakama Reservation. Wildfire smoke that had caused the air quality to reach unhealthy levels for sensitive groups is under control and the air quality monitor readings are in the more normal range.
