An upper level trough of low pressure (shaded “U”shape) is sliding eastward and will keep the clouds and precipitation  with us.  The next frontal system has returning the clouds land just a touch of showers and there is another one right behind it. The jet stream will set up in Zonal Flow which means the moisture feed will be moving pretty much on a straight line from West to East. Another frontal system push through the Pacific Northwest late Friday and Saturday.

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 bringing more wet weather and cooler temperatures. High pressure (shaded “Arch” shape) will try to take over and dry us out early next week, but will only succeed for Tuesday. A storm system will approach the Pacific Northwest in the middle of the week returning the sowers Wednesday.
