Here is my weekly weather quiz question. What is a “Cold Air Funnel“? The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
________________
Upper Level High Pressure (Shaded “Arch” shape with blue arrows) is still in control producing sinking air the result of which is late night and early AM fog with freezing fog in many locations. An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) will move closer taking over for 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 Sunday through next Thursday.
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.
