Here is my weekly weather quiz question for the last time. What is “a Depression?” Here is the correct answer. A Depression is a region of low atmospheric pressure that is usually accompanied by low clouds and precipitation. The term is also sometimes used as a reference to a Tropical Depression. 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 large upper level low (Shaded U shape with blue arrows) continues to send frontal systems at us. A frontal system moves through part of the Pacific Northwest and slides southward. More frontal systems in the parade of storms move toward us Wednesday.  By Saturday yet another frontal system pushes into Oregon. Willamette Pass, Hoodoo and Mt. Ashland are all open with great ski conditions. Check their websites for updates.
