Here is my weekly weather quiz question. What type of cloud appears as a lens or almond shape and where can they usually be found? 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 jet stream shows a large trough of low pressure ( “U” shaped area over us) that pumped a lot of moisture our way. A frontal system has pushed through the Pacific Northwest bringing rain, wind, and lowering snow levels with it with more to follow behind it and another one is sliding down the California coast causing some very active weather there. It looks like we’ll get another burst of colder air from Canada by the middle and end of next week.
