Please post your answer as a comment after the forecasts. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. Good luck.

An upper level low will slide into the low pressure trough over Washington and Oregon (see “U” shape formed by the blue arrows) keeping us in 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 and in the valley areas early in the AM and late at night. A weak cold front moved down from the Northwest Saturday causing some minor precipitation mainly in the mountains and moved though Montana. A cold front will attempt to move in next weekend, 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.
