The weather locally is pretty mild, 25-45 in the winter with one or two light snowfalls (2"-4", gone in 3 days)...summer 50--80F, not too humid, short mosquito season.
Oregon and WA both have a "wet side" and a "dry side." the western/ocean side is wet in both states, and east of the mountains (Cascades) is much dryer, colder in winter and hotter in summer. Wages are generally lower, but so is rent and housing (but not by much, Spokane avg house is $200K).
