It’s a good start to winter at Northwest ski areas if they can open by Thanksgiving weekend.On cue, serious snow fell on Turkey Day at Mount Hood this year. By Black Friday, both Timberline Lodge and Mount Hood Meadows were operating, although on a limited basis with a reduced number of chairs.This Monday, Mount Hood Meadows began daily operations, two weeks earlier than normal.Timberline Lodge on Wednesday was operating six chairlifts with a 73-inch base at the lodge.Mount Hood Skibowl, the third big ski area on the peak, started tubing on Dec. 3 and its chairlifts at 3 p.m. Wednesday.“This is the best start to the season in a decade,’’ said Dave Tragethon, vice president of communications for Mount Hood Meadows. “Most recently we haven’t had enough snow to offer daily operations until later in the month. These storms aligned to give us a fast, early start to the season, providing enough snowpack to open even our lowest elevation lift and the nordic center.’’Night skiing at Meadows is planned for Friday and Saturday. Beginning Dec. 16, the ski area will move to its holiday schedule, with chairlifts operating from 9 a.m. to 9 p.m. daily through Jan. 1, with the exception of Dec. 19, Dec. 20 and Christmas Eve, when the lifts close at 4 p.m.
