An upper level trough of low pressure (Shaded area then the east side of “U” is formed by the blue arrows). That means the airflow is from the Southwest which brings in more moisture and a new frontal system that will move in from the Northwest. By Wednesday another stronger frontal system will be poised to push more rain into Oregon.

A high pressure ridge (the “arch” formed by the blue arrows sitting over the Pacific Northwest) is weakening and  will be replaced by an upper level low (the “U” formed by the blue arrows) behind it. Notice the blue arrows from the low are moving toward us and bringing the airflow more from the Southwest which brings in more moisture and a new frontal system that will move in from the Northwest. By Wednesday another storm system will be poised to push more rain into Oregon.

It took an extra day, but we have a winner for my weekly weather quiz. Here is the question. What is the “Green Sky” effect? Congratulations to Amber for being the first person to post the correct answer. Here is what she posted. I believe that the green sky effect means bad weather is coming, such as a tornado. The sky is blue due to the scattering of light from the water droplets, which means that sky turns green when there is an excess of water droplets in the air. This is not the same this as the green flash phenomenon. But I am sure that both are gorgeous. Great answer! Amber wins a week of free personalized forecasts. I’ll have another quiz question for you on Monday. Remember, the first person to post the correct answer will win one week of free personalized weather forecasts tailored to your needs.

Here is my weather quiz question for this week. Since I have had web access issues this week  I will give you an extra day (today) to  come up with the correct answer. What is the “Green Sky” effect? Please place your answer as a comment after the forecasts. The first person to post the correct answer will win one week of free personalized weather forecasts tailored to your needs. Good luck.

_______________

A high pressure ridge coming out of the Gulf of Alaska  (the “arch” formed by the blue arrows offshore aimed at Canada) and  surface high pressure (the “H” off the Oregon coast) are drying us out and warming  us up with temperatures above average for the interior valleys then cooling back down. High pressure will weaken and allow low pressure to take over toward the end of the weekend into next week allowing a series of storms to move through the Pacific Northwest.

A high pressure ridge coming out of the Gulf of Alaska  (the “arch” formed by the blue arrows offshore) will dry us out and warm us up with temperatures getting about 10 degrees above average for the interior of Oregon. A frontal system will be pushing into the Pacific Northwest between Sunday and Monday bringing back the chance for rain.

A trough of low pressure (the shaded “U” ) is stretching south into California and a surface frontal system has moved southeastward with it our chances for getting wet. High pressure coming out of the Gulf of Alaska  (the shaded “arch”) will dry us out and warm us up. Another frontal system will be pushing into the Pacific Northwest Thursday night through Friday to bring back the chance of rain. By Monday a third frontal system will be offshore ready to bring in even more rain.
