Cold high pressure (shaded “Arch shape”) moves over the Pacific Northwest. A frontal system can be seen as it moves down from the North through Oregon bringing colder air and more sunshine with it. That ridge aloft along with high pressure (Blue “H”) at the surface will keep storm systems away from the Pacific Northwest.
