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. Another trough of low pressure follows close behind with a surface frontal system is bringing the rain chance back quickly. High pressure will slide back in drying us again Friday lasting for at least part of the weekend.
