Last real snow I remember having in Glasgow (moved in 1980) was on New Year's Eve/Day around 1977 give or take a year.

Most Americans I talk to tend to think of Scotland as a very cold place with tons of snow every winter and are always shocked that it's not the case - at least for the Central belt. We get worse winter weather here in Philly and we almost get used to it. The City more or less shuts down at more than 6 inches.
People to the North or West of here would laugh at our attempts to cope. People to the South would marvel. All depends on what you're used to.

Good luck over there.
