Here is my weekly weather quiz question for the last time. What is “Obscuration?” Here is the correct answer. Obscuration is any atmospheric phenomenon, except clouds, that restricts vertical visibility (e.g., dust, rain, snow, etc.). 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.
