Here is my new weekly weather quiz question. What is an “occluded front?” Please remember to 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.
An upper level high pressure ridge (shaded “Arch”shape) gave us plenty of sun and warm temperatures, but a low pressure area (shaded flattened out “Crescent” shape) that’s been sitting offshore is sliding eastward through California south of us giving us a chance of showers. A frontal system broke apart and slide south of us just like the last one did.
