Here is my new weekly weather quiz question. What is an “occluded front?”  Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count. Good luck.

An upper level low (Shaded “U” shape with blue arrows) has returned the flow of moisture over us. A cold front, pushed by the upper level low, moved through Oregon Monday. An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) will return to slowly warm us up and dry us out later this week.
