The only model left that gives PDX meaningful QPF tomorrow afternoon and evening is the GRAF. I think the best we can hope for up here is 1-2 spotty inches. Most areas will get skunked or get very little. Better odds south of us, but I am not convinced that anybody from Eugene to Salem will score big either. Much better odds at a widespread couple of inches though in my opinion.
Thursday sure looks cold for the Portland area either way.
