They asked if we always have such wonderful conditions this time of year, as the Alps are pretty much never this good so early anymore.
Resorts that average ~250 inches a year are never a safe bet for full operation at Christmas. Just modest deviation on the downside will result in an inadequate base on anything steep or rocky. That applies to Colorado as much as the Alps. Front Range/I-70 Colorado has had a distinctly above average start this season. Maybe qualitatively better than that considering the dump of dense base-building snow a week ago, topped off by some light powder at Christmas.
Christmas and other school holidays also have crowd issues. But we should be jealous of the Euros with their February/early March holidays right in the sweet spot for ski conditions at most areas. The latter holidays should always be preferred to Christmas if you have to choose just one.
As for the "anymore" part of the above quote, I do not have as much data from the Alps to refute that as I do here. The rain/snow line may have risen some over the past 30 years, and there are some places in the Alps that could be vulnerable to that. But above ~1,700 meters I would say almost certainly no change in snowfall trend or incidence within the season.
Weather is volatile and busted Christmases will occur occasionally in most places. What's happened in the Alps this season is no different from what happened in Colorado 3 years ago.
