Is there cleaner air in our future?

  A cold front passage tonight will bring gusty winds and cooler 
  temperatures for the rest of the work week. There is a chance of 
  showers for north Idaho Thursday and Friday. After a chilly start 
  on Saturday, anticipate dry and milder weather. The next chance of
  rain looks to arrive Sunday night into Monday followed by breezy 
  and cooler conditions.


For the Wednesday into Friday communities that are near existing large fires will continue to deal with overnight smoke into their valleys.  Areas such as Winthrop in the Methow valley to the South of the Diamond Creek fire should be aware of this given the forecast for winds out of the North through Thursday.


Western Washington should remain clear of the smoke.
Eastern Washington areas around Spokane and North should also be breathing cleaner air.
Walla Walla is seeing some smoke today from a Central Oregon fire that made a significant run yesterday.
The Methow, Chelan, Wenatchee, Kittitas and Yakima valleys are our areas of concern for the next few days.


There is good news on the horizon.  The trend is for lower temperatures and higher relative humidities across the entire inland Northwest from Friday through the weekend, with a much anticipated, much needed chance of widespread precipitation to support the firefighting efforts by early next week!
