Wednesday: Smoke will linger in
Chelan and Manson throughout the morning, lift a little in early afternoon
and settle back into these areas with the corresponding growth of northwest winds
and corresponding fire activity. The upper Methow Valley will see a similar
pattern with a brief clearing of the air in mid to late afternoon followed by
a return of smoke from active fires north of the area. Being closer to the
fires, Methow will likely see similar smoke conditions as Chelan throughout
the day. Smoke will remain in Leavenworth
and Wenatchee throughout the morning; clearing by mid to late afternoon.
Thursday: Smoke will linger in Chelan and
Manson throughout the day, becoming worse in late afternoon. The upper Methow
Valley will see smoky conditions until a late morning lift in the
inversion. Methow will see variable
smoke conditions throughout the day. Leavenworth
and Wenatchee will be spared from smoky conditions and see good air quality
throughout the day.
Friday: Between inversions holding in smoke, northwest winds with
enhanced fire activity throughout the day, Chelan and Manson will not likely
see much relief from smoke. Gusty northwest
winds will keep Leavenworth, Wenatchee and the Methow Valley free of smoke
from these fires for most of the day; smoke may settle in these areas
overnight.
