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 storm will be approaching the coast soon. There will be an outdoor weekend due to surface high pressure (the blue “H” off the coast and two inland) followed by yet one more frontal system (position shown is Wednesday).
