We didn’t get quite as warm as I expected Tuesday, but today really did warm up. By Friday this frontal system (position shown is Saturday with another one following) will be approaching the Pacific Northwest. And, of course, a new frontal system shows up offshore next Tuesday.

A frontal system pushed into Oregon Sunday bringing the chance of showers with it. An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) will take over keeping the week dry and warmer. By Friday this frontal system will be approaching the Pacific Northwest. And, of course, a new frontal system will be located behind that one.
