Sorry, no winner this week. One person did come close. Here is my weekly weather quiz question for the last time. What is a “lahar.” Here is the correct answer. A lahar is a type of mudflow or debris flow composed of pyroclastic material, rocky debris, and water. The material flows down from a volcano, typically along a river valley. It is very dangerous because it’s consistency and the way it acts is very much like cement. It is liquid when it’s moving, but when it stops, it solidifies. This can cause just as much devastation as lava itself. I’ll have another weekly weather quiz question for you starting on 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 with blue arrows) has moved to the east a bit, but still centerer over western Oregon, (see blue arrows curving from the northeast) and a thermal trough of low pressure (dashed line along the Oregon coast) our weather pattern will remain stable. We’ll have chilly nights followed by pleasant days with sunshine and average temperatures through the weekend, Columbus Day and beyond. It looks like we may have a small chance of rain next Friday and Saturday, but that is a long way off to be very certain if it will in fact occur.
