No winner this week. Here is my weekly weather quiz question for the last time. What is an “occluded front?” here is the answer. An occluded front is produced when a cold front catches up to and overtakes a warm front. For more details click here. I’ll have another weekly weather quiz question for you starting next Monday. 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.
