No winner this week. Here is my new weekly weather quiz question for the last time. What is an “occluded front?” Here is the correct answer. ” An occluded front is a composite of two fronts, formed as a cold front overtakes a warm or quasi-stationary front. Two types of occlusions can form depending on the relative coldness of the air behind the cold front to the air ahead of the warm or stationary front. A cold occlusion results when the coldest air is behind the cold front and a warm occlusion results when the coldest air is ahead of the warm front.” 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.

An upper level trough of low pressure (shaded “U”shape) is sliding eastward and will keep the clouds and precipitation with us. A frontal system has moved through Oregon and is being followed by another one, as usual. High pressure (shaded “Arch” shape) will try to take over and dry us out early next week. A storm system will approach the Pacific Northwest in the middle of the week.
