You pose some interesting questions Thelma.
Our average snowfall is 31.2" and the official depth of Saturday's snowfall was 30.2" so, we have about an inch to go in "x" number of storms to go above that average.
Normal? There are a few weather forums I frequent and the discussion is since 2000, the average snowfall hasn't changed much since 1980, what has changed is the time of year that we get that 31.2", and the severity of the storms.
Back in the day when I was a kid,
Winter lasted from the end of December to the last of March and you could expect snow before Thanksgiving in November to April, 1st with December/January the worst.
Nowadays we have the same season, but that snow comes usually the end of January and can last until the end of April with February being the worst so the productive part of the season has shrunk by 10weeks, or 6weeks at the beginning of the season and 4weeks at the end, this past storm is somewhat of an aberration.

Without empirical evidence I can say that I have noticed the years from 2010 to now as being the warmest; Fall, Winter, and Spring being compressed from what we normally experience and Summer's warmth expanding into those other three seasons. This past December is the warmest for us since records started being kept back in 1888.
Earth works in cycles not only caused by itself mainly from volcanic activity, but also external influences caused by humans, animals and plants. Is it the start of run away global warming? I don't believe so, but I do believe we are entering or in a new cycle, like you mention; "sort of normal wave to the way it all happens". If we can do something about it, we should for posterity.
Without more information on the geographical and cultural aspects of Triol it would be difficult for me to explain why the residents see a 69minute difference in when the Sunlight hits the farmhouse window.
I would find it hard to believe large lakes or the change in axial tilt and precession would have a recent effect on the Sunlight/window timing, these affects are real, but so minuscule that people would have a hard time noticing them without empirical evidence.
In speculating, it could be the Alps or the farmhouse has shifted in their positions since the observation was first made. When was the observation first made?
Unless documented, traditions have a way of being embellished, but you say "recently", describe recently for me; Since last Winter, 5 to 10 Winters ago, decades? Has anything catastrophic happened to the area in the last several years, say an earthquake, landslide, avalanche?
Thanks Jack, nice links. And Mike, we're subsidizing his flood insurance.
