No winner this week. Here is my weekly weather quiz question for the last time and the correct answer. Define a “fallstreak.” Here is the answer: A fallstreak is another name for “Virga” which is precipitation falling from a cloud, but it evaporates before it reaches the ground. Click for more details. 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.

An upper level trough of low pressure (shaded “U”shape in blue arrows) is still pushing subtropical moisture into the Pacific Northwest that is coming from Hawaii (called the “Pineapple Express”). That is why our temperatures have stayed well above normal. A frontal system moved through Oregon and more are on the way. Here is a look at a frontal system that will push in by Tuesday (position shown in Wednesday) to keep the parade of storms going. A happy note for skiers, Mt. Ashland says they will open this Thursday. Hoodoo and Willamette Pass are still closed waiting for more snow.
