Here is my weekly weather quiz question for the last time. What is a “debris cloud?” Here is the correct answer. A Debris Cloud is a rotating “cloud” of dust or debris, near or on the ground, often appearing beneath a condensation funnel and surrounding the base of a tornado. This term is similar to dust whirl, although the latter typically refers to a circulation which contains dust but not necessarily any debris. A dust plume, on the other hand, does not rotate. Note that a debris cloud appearing beneath a thunderstorm will confirm the presence of a tornado, even in the absence of a condensation funnel. 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.

High pressure (Shaded “Arch” shape with blue arrows) returns to warm us up again for the rest of this the weekend. The Summer Solstice takes place at 9:38 AM Sunday officially ushering in Summer. An upper level low will start to take over increasing clouds and cooling us back down Monday, then warming back up again for the rest of the week.
