Here it is Monday again and that means I have my new weekly weather quiz question for you. Here it is. This is an easy “Fall” question. What makes the leaves lose their green color and fall off of the trees? 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 air trough of low pressure (“U” shape on the orange jet stream line) is sending even more moist cooler air our way. One frontal system came through already and a second even stronger one (shown offshore) is sweeping into Oregon dropping more rain on us.
