Here is my weekly weather quiz question for the last time. What is “a Tail Cloud?” Here is the correct answer. A Tail Cloud is a horizontal, tail-shaped cloud (not a funnel cloud) at low levels extending from the precipitation cascade region of a supercell toward the wall cloud (i.e., it usually is observed extending from the wall cloud toward the north or northeast). The base of the tail cloud is about the same as that of the wall cloud. Cloud motion in the tail cloud is away from the precipitation and toward the wall cloud, with rapid upward motion often observed near the junction of the tail and wall clouds. Compare with beaver tail, which is a form of inflow band that normally attaches to the storm’s main updraft (not to the wall cloud) and has a base at about the same level as the updraft base (not the wall cloud). 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.

A high pressure ridge (Shaded “Arch” shape in blue arrows) is starting to weaken as the airflow from the south has brought clouds and the chance of showers and thunderstorms to Oregon. An upper level trough of low pressure (“U” shape) will be moving into the Pacific Northwest over the weekend keeping us under the cooler weather pattern.
