An upper level low over Washington and Oregon (see “U” shape formed by the blue arrows) is increasing the onshore air flow as it moves to the East.. That means more clouds and even a chance of some light rain or drizzle along the Oregon coast. A weak cold front moved down  from the Northwest Saturday causing some minor precipitation mainly in the mountains and moves though Montana. Another cold front will attempt to move in but will get stalled North of us and then get pushed back to the North away from us. 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.
