Depends upon what kind of skiing you want to do.
North of Chelan/Wapato is Methow valley, which has great cross-country skiing. (I haven't been skiing there myself, but my x-country friends love it).
More likely to have skiing in Methow area or Mazama/Winthrop than down-hill skiing in Mission Ridge ski area outside of Wenatchee.
Wenatchee is south of Chelan, and Mission Ridge might have been hard hit last year from warm weather. Many ski areas in Washington were.
Bill4728 would have a better idea than most here on Tug.
