A Metro bus is routed around a tree that fell across Highway 99 in north Seattle Wednesday, Dec. 24, 2008, following more overnight snow. A week of heavy snow, jammed airports, closed roads and cabin fever had many Washington residents wishing for that traditional Northwest holiday: a rain-soaked Christmas. For much of Western Washington at least, rain and the possibility of ice-free streets was on the way, the National Weather Service promised Wednesday, but not before one more snowfall due Christmas morning.
