A high pressure ridge (“Arch” shape on yellow line) pulled away from us and a trough of low pressure (“U” shape on the yellow line) took over returning the wet weather pattern. Another high pressure ridge cleared us out today. A warm front sits offshore today then pushes through returning the rain to the Pacific Northwest. There will be even more frontal systems (position shown is Wednesday) sliding over the high pressure that will keep the showers around for the week.
