No winner this week. Here is my weekly weather quiz question for the last time. What is “a Hyetograph?”  Here is the correct answer. A Hyetograph is a graphical representation of rainfall intensity with respect to time. I’ll have a new weekly weather quiz question for you starting Monday. 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.

Now upper level low pressure ( shaded “U” shape with blue arrows in first graphic) is sliding in. The chance of rain returns as early as late tonight as another frontal system marches into Oregon.
