________________

An Upper Level Low Pressure Trough (Shaded “U” shape formed by arrows) continued to give us a northeasterly airflow which allowed the wildfire smoke to continue to be a problem. Our air quality is back to normal, but with wildfires still scattered over the state the haze and smoke will return. The graphics for days 1-3 show the front that that moved through and is cooling us off and cleaning up the air. The graphics for days 3-7  show a frontal system moving into and through the Pacific Northwest between Wednesday and next Thursday.
