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 temporarily. A warm front pushed through returning the rain to the Pacific Northwest. Another frontal system (position shown is Friday) will be sliding over the high pressure that will keep the showers around through the weekend and beyond.
