No winner this week. Here is my weekly weather quiz question for the last time. Please define the term “acid rain.” Here is the correct answer. Acid Rain is rain containing relatively high concentrations of acid-forming chemicals that have been released into the atmosphere and combined with water vapor. It is harmful to the environment. 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.

Upper level high pressure (Shaded “Arch” shape with blue arrows) has cleared us out for the time being returning the sunshine. An upper level low (Shaded “U” shape) will take over spreading rain or showers throughout the Pacific Northwest and dropping temperatures drastically.

Advisories: None at this time.
