Sorry, but no winner this week. Here is my weekly weather quiz question for the last time. What is “AFOS” and why is it being replaced by “AWIPS?” Here is the correct answer. Automation of Field Operations and Services (AFOS) is a computer system linking NWS offices for the transmission of weather data. This system was installed in the early to mid 1980s and it is being replaced by Advanced Weather Interactive Processing System (AWIPS). I’ll have a new 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.

An upper level trough of low pressure (Shaded “U” shape) is moving eastward away from the Pacific Northwest taking storms away. A frontal system pushed through bringing more clouds and precipitation to the Pacific Northwest and colder temperatures. A complex frontal system will return the stream of moisture pouring into Oregon by midweek bringing the “Spring Rain.” Spring officially begins with the “Vernal Equinox ” at 4:02 AM Wednesday March 20th.
