Ignoring your 50-60 degrees, this matches The Netherlands quite well. When I grew up in that magical place, snow was a regular occurrence (not all winter long, but snow happened every year, as did ice skating on rivers). Now, when it happens, it is a rare exception.

I actually found a graph for it, but can't account for its veracity. It shows the number of days per year with complete snow cover, over the past 60 years: https://www.weerwoord.be/m/2466231
