An upper level low pressure trough (the “U” shaped dip in the yellow jet stream line) is moving eastward over the Pacific Northwest. High pressure aloft (the “arch” shaped yellow line) will build in keeping much needed rain away from us. A cold front will slide down from the Northwest next weekend. Also, be prepared for possible smoke high over the area from fires in British Columbia. More smoke, this time at the surface, is collecting over the Deschutes National Forest could slowly move toward us because of the offshore airflow pushing it from East to West.
