Here is my weather quiz question for this week. There is an old saying “Cold is the night when the stars shine bright.” What does this saying mean and how does it happen? Please 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.

A weak upper air high pressure ridge (“arch” shape) gave us a bit of a break from the rain, but another frontal system has pushed into the Pacific Northwest bringing rain and cooler temperatures with it. There will be sunshine for an outdoor weekend due to a high pressure ridge that will keep us dry with sunshine. Another frontal system will be moving in early next week and taking the sunshine with it.
