Sorry, no winner this week. Here, for the last time, is my weather quiz question. In the Willamette Valley what does it mean when you see large numbers of sea gulls gathering at school and supermarket parking lots? Some posted answers have been close but not exactly what I was looking for. The answer is the birds are riding in on the higher winds most often produced ahead of strong storms as they approach the coast. They don’t have to flap their wings as hard due to the higher tail wind and they travel to the areas where they can easily find food. School and supermarket parking lots always have some dropped or discarded scraps of food on them. I’ll have another weekly weather quiz question for you starting next Monday. Please post your answer as a comment by clicking on “no comments/commemnts” 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 air trough of low pressure (“U” shape) moves across Oregon. A warm front is on its way through the Pacific Northwest with a cold front behind it. That means more precipitation this AM. Late this afternoon through Sunday should, and I emphasize should, be for the most part dry, then more storms will bring back the rain for next week. The airflow will straighten out quite a bit and that will decrease the flow of colder air that has been coming out of the Gulf of Alaska. The result will be slowly warming temperatures.
