Sorry, no winner this week. Here is the question for the last time. What are the three conditions needed to form a rainbow? Here is the answer.

“Three conditions must be met in order for you to see a rainbow. First, it must be raining. Second, the sun must be shining. Third, the observer must be between the sun and the rain. The lower the sun is in the sky, the higher the arc of the rainbow will be.”

I’ll have another weekly weather quiz question for you starting next Monday. Remember to 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.

The jet stream shows another cold trough of low pressure ( “U” shaped area) migrating Eastward across the Pacific Northwest. The precipitation will be continuing in waves as a new frontal system marches through Oregon. A bit of a break for Sunday, but for the most part our near future will stay wet. More frontal systems will be coming our way next week producing even more precipitation.

Advisories: NONE AT THIS TIME.
