Smoke forecast through Wednesday 26 August

Most of Western Washington cleared out as expected overnight and is showing Good air quality. Overnight temperature inversions will make small valley communities a little slower to clear out today.

Eastern Washington: strong southwest winds will pick up later today. While this increases fire risks, it will also help clear out smoke in the Columbia Basin and surrounding communities. Expect air quality to reach Good to Moderate levels in these areas today. Smoke in the Lewis-Clark valley and parts of Klickitat County might be slower to clear out, so may not improve beyond USG today.

Weather models are having a hard time with forecasts through the rest of this week. As of now the best available info for Tuesday and Wednesday calls for lighter winds and warm temperatures. This could cause some pooling of smoke around the above-mentioned communities, and lead to USG or Unhealthy air on occasion. In general, poor air at night and some clearing during the afternoon.

Forecasts for northcentral and northeast Washington communities are covered in other blog posts.

BTW, here's an interactive map of all the current fires with clickable info, tweets, Flickr pictures and other multimedia links.
