An upper level low (Shaded “U” shape with blue arrows) brings onshore airflow and increased chances of wet weather. A surface frontal system has returned cooler air and the chance of showers. A high pressure ridge takes over keeping the rain away for a while. A frontal system will be lurking just offshore Sunday morning, but it looks dry and should only cool us a bit for Mother’s Day.

Here is my weekly weather quiz question for the last time. What is a “Roll Cloud?” Here is the correct answer. A  Roll Cloud is a low, horizontal tube-shaped arcus cloud associated with a thunderstorm gust front (or sometimes with a cold front). Roll clouds are relatively rare; they are completely detached from the thunderstorm base or other cloud features, thus differentiating them from the more familiar shelf clouds. Roll clouds usually appear to be “rolling” about a horizontal axis, but should not be confused with funnel clouds. I’ll have a new weekly weather quiz question for you starting 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. Good luck.
