Statewide forecast � Aug. 30: Labor Day Weekend
Fire activity has decreased significantly this past week, so smoke should be limited to areas immediately downwind of smoldering fires. With no big warm up expected and moist overnight humidity, fire growth should be minimal. Furthermore, there is potential for rain in British Columbia (including Vancouver Island) Sunday night and Monday which could further decrease wildfire activity there. Most areas of Washington state should have Good air quality this Labor Day weekend.
Western Washington:
It will be relatively cloudy and cool over most of Western Washington for the next couple days, but Sunday should be mostly sunny in the low to mid 70s. Monday morning has the potential for some light rains, especially as you get closer to the Canadian border. Air quality should be Good to Moderate in most places for the weekend.
Central and Eastern Washington:
Due to the proximity to local wildfires, we continue to see air quality fluctuate between Moderate and Unhealthy in areas like the Methow Valley, Pasayten, and Chelan. This will likely continue through the weekend. Some of the smoke from fires in the Cascades even made its way across the Columbia Basin and into Spokane early this morning. Air quality was Unhealthy for Sensitive Groups, and a little worse for a few hours. That smoke has mostly cleared, but the Spokane area could potentially see more of these short smoky events over the weekend. Air quality in the Columbia Basin and Northeastern Washington should mostly be in the Good to Moderate range this weekend, but there could be some intermittent smoke impacts that get into the Unhealthy for Sensitive Groups category. Southern counties in particular can expect continued Good to Moderate conditions.
There is some fire activity north of Stevens county in Canada that could carry smoke into Northeastern Washington on Saturday and cause Moderate to Unhealthy conditions. Any of that smoke should clear out by Sunday with the expected southwesterly winds.
Sunday and Monday will feature high temperatures in the upper 70s to mid 80s for most areas.
Overall, expect dry and comfortable weather through Labor Day, with enough winds in the afternoons to provide good ventilation.
