Advisories: NONE AT THIS TIME.

A high pressure ridge (“Arch” shape on yellow line) has moved away and a trough of low pressure (“U” shape on the yellow line) is taking over. A frontal system pushed through to the southeast dragging rain along with it, while another one is just starting to move into the Pacific Northwest. A short dry period Wednesday, but there will be even more frontal systems (position shown is Thursday) that will keep the showers around through the week.
