The mild storm that passed through the Mid-Columbia on Sunday improved air quality in the Tri-Cities on Monday, but patches of smoke are possible again today.
The National Weather Service has extended an air quality alert for the Mid-Columbia through Friday because of Washington wildfires that continue to burn.
On Monday, the Benton Franklin Health District lifted its recommendation that school districts and childcare centers keep children in elementary school or younger indoors at recess and cancel other outdoor activities.
Washington listed the air quality in the Tri-Cities as moderate Monday, which is a step below good. Walla Walla air improved enough to be listed as good. However, the air quality was worse west of the Tri-Cities.
Also Monday, Gov. Chris Gregoire extended a ban on all outdoor burning for all counties east of the Cascade crest through midnight Sunday.
