An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) will move closer taking over from the High Pressure and enhancing the chance for precipitation. The graphics for days days 1-3 show the frontal system moving into the Pacific Northwest Friday. The graphics for days 3-7 show the parade of frontal systems starting to move toward and then across the Pacific Northwest Monday through next Friday.
Note: The overnight air quality in Eugene/Springfield and Oakridge has become bad enough for a Red Home Wood Heating Advisory to be continued for yet one more day.
