Layers... you want to be prepared to add and shed clothes as needed. The weather in the Pacific N.W. is fickle. You can have the comfortable temps as described above during some days and it can from time to time drop to the low 40's high 30's at night on extreme days. The waterproof and wind proof idea mentioned above is the best advice. Make sure it has a hood.
Sweaters, turtle neck shirts, coat, outer rain/wind breaker, comfortable but rugged shoes/boots, insulated if you have 'em. If not heavy socks. As the Boy Scouts say... "Be prepared". Especially if you have a balcony or are going to spend time on the decks. The wind and drizzle can make you very uncomfortable if you get damp/wey.
