An upper level low over Eastern Oregon (see “U” shaped area of white line) that has been keeping us in the onshore air flow is moving to the East. High pressure will start to build up giving us offshore flow and warming us up quite a bit Friday, Saturday, and Sunday. Another trough of low pressure will develop and move toward us Monday to Tuesday cooling us back down again.There is still smoke high in the atmosphere over us from Canadian fires. So far that smoke has not come down to the surface. Smoke is still collecting over the Deschutes National Forest near Sisters and could slowly move toward us if and when the offshore airflow returns pushing the smoke from East to West.
