Here is my weekly weather quiz question. What is the difference between a “Typhoon” and a “Hurricane”? 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) turned our airflow more from over the ocean (the term for that is flattening as it lost it’s hump), for more rain chances because it is pumping subtropical moisture into the Pacific Northwest. Since the moisture feed is coming from Hawaii it is nick-named “The Pineapple Express.” Behind the ridge is an upper level low (shaded “U” shape on previous graphic). A frontal system moved through and another is following right behind it. The wet weather pattern will last through Halloween. Prepare your Trick-or-Treaters for the wet weather. We could see at least one dry day on Thursday.
