No idea how the ECMWF thought it would be 69 at SEA today. Currently 75. I think this adds to the notion of overachieving temps when it's just really a cool bias on the most trusted model overall.
No really... that is pretty variable. And when troughs are just to the west or north they can bring extremely nice weather in the summer. I don't want red parked over us for weeks... that would just turn to smoke
