A big change to our overall weather pattern in western Washington is forecast to happen the last week of August.
For the first time in a long time, we will see a persistent easterly offshore flow which will help give us a streak of warm temperatures, as well as potentially give us some wildfire smoke. Before we get too hyped up, let's point out there are no major wildfires currently burning in eastern Washington or interior British Columbia.
The biggest fire is the Williams Flats Fire which had burned around 45,000 acres and was about 90% contained Thursday morning. That fire isn't producing much smoke, so even with an easterly flow, it likely won't bring much smoke to western Washington.
