Sky is graded over the ski day, 9am to 4pm. Bluebird means at least two of the three models show clear skies all day, none shows overcast, and no snow or rain is forecast. Models are weaker on cloud than on snow, and none of them can see valley fog, so treat it as a good sign rather than a promise.
