Here is my weather weather quiz question for this week. You have probably heard the term “fronts” used to explain the boundaries between cold and warm air masses. Who first coined that term? 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.
