Air Quality forecast, 8AM Friday 21 September 2012
Issued by Ranil Dhammapala, Washington State Dept. of Ecology

Western WA has cleared out well under the stronger marine push and will stay that way today. Air quality in the Columbia Basin and the Palouse/ Spokane has been deteriorating very gradually over the last few days and is mostly in the "Unhealthy for sensitive groups" category this morning. Air in these areas may improve slightly but not hugely, Saturday evening through Sunday evening.

The areas of serious concern- located at the eastern foothills of the Cascades- continue to remain problematic. Air in Wenatchee has remained in the "Hazardous" category for several days now, with each day being a little worse than the previous. Cashmere and Entiat are in a similar situation, while Leavenworth, Ellensburg, the upper and lower Yakima Valley and Chelan have been recording Very Unhealthy conditions. This scenario is not expected to change much over the next few days.

The approach and passage of a low pressure system Friday night through Saturday evening gives rise to a small threat of dry lightning in the Washington Cascades mostly south of Lake Chelan. Given the dry fuels in the area, we can only pray that there won’t be new fires for the already stretched firefighters to contend with.

Some cooler temperatures are on tap for eastern WA next week and this should help reduce fire activity, but the kind of soaking rain needed is a notable absentee from the forecast.

The National Weather Service issued an Air Quality Alert for much of eastern Washington:
