Temperature wise it's doable, except for the few days a year when we actually get snow and people lose all ability to drive. Oh, and make sure you get a good set of rain gear, cuz all it does is rain for about 4 months straight.
Pretty much what was said above. Lots of rain between March-June. Some rain from Oct-Feb. 2-3 days of snow in Jan/Feb. While it only dips below zero briefly in winter it can feel very cold due to the moisture level.
