Here is my new weather quiz question for this week. On average there are about 50,000 of these per day over the world and 10 million of them in a year. What kind of weather event am I describing? Please post your answer as a comment after the forecasts on this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. Good luck.

_______________

The upper airflow is moving from Northwest to Southeast bringing warm then colder air toward us. A warm front is moving through the state of Oregon and a cold front will drop down behind it. Then another trough of low pressure will slide in along the coast sending more storms our way. A complex frontal system ( position shown is  Thursday AM) will push into Oregon Wednesday.

Yes, we have a winner. Congratulations to Amy Buchmeier Here is this week’s weather quiz question for the last time. This is a very basic weather question. What is a “rain shadow?” For extra ah ha points how does it work in Oregon weather? Here is her answer: “A rain shadow is the dry side of the mountain…caused by the moisture in the air being release on the windy side or the top of the mountain. By the time the clouds reach the “backside” of the mountain, most of the moisture is gone leaving a dry area…also known as a rain shadow? In Oregon, I would guess the east side of the Cascades are rain shadowed as the moisture leaves the coast and travels over the mountain range.” I’ll have another weekly weather quiz question for you starting Monday.  The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs.

An upper level trough of low pressure (“U” shaped shaded area) has moved Eastward and a weak ridge of high pressure (“Arch” shaped shaded area) has cleared us up just a bit for today as a warm front approaches. Another trough of low pressure  follows close behind and will be bringing the rain chance back quickly. A cold front will push through Oregon between Monday night and Tuesday.
