Sorry no winner for my weekly weather quiz question this week. Here’s the question again. What type of cloud appears as a lens or almond shape and where can they usually be found? Here is the answer. They are called lenticular clouds because they are shaped like a lens. They are most commonly found above higher terrain like a mountain or a butte. For more details and a picture of a lenticular cloud. I’ll have another weekly weather quiz question for you starting next Monday. 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.

The jet stream shows a large trough of low pressure ( “U” shaped area over us) that pumped a lot of moisture our way.  It will move away from us, but another upper level low will swing down about mid week. A frontal system has dropped Southward through California with  a break in systems behind it and it looks like we’ll dry out for the rest of the weekend before more storms head toward us next week. Another burst of cold air will follow a frontal system late in the week.
