Here is my weekly weather quiz question for you this week. Why are clouds white? It’s actually pretty easy. Please post your answer as a comment by clicking on “no 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.

The upper airflow shows a stronger high pressure ridge building over the Pacific Northwest, but a weak cold front is sliding down in front of it which brought clouds, but not much chance of significant precipitation. The ridge will protect us at least until next weekend when the computer models indicate a wet weather pattern may begin as another frontal system moves in. Remember that, particularly this time of the year, when it’s not raining it is usually fogging.
