The UK doesn't get much snow. We're at a higher latitude than the States, apart from Alaska, but the gulf stream keeps us at drizzle and clouds instead of snowstorms. So we're not very good at dealing with snow.
The BBC reports 'heavy snow' in northern Scotland - 'up to 10 cm'. That's four inches.
I don't think I've ever seen four inches of snow in my life!
Very light - The earth is perceivable white
Light - 1 to 10cm
Medium - 10 to 50cm
Pretty heavy - 50 to 100cm
Heavy - 100 to 150cm
Very heavy - More than 150cm
In Finland, snow appertain to a normal winter. I don't know how much would be an average and of course the volume of snow depends on it where you are located. In Lapland (north Finland) temperatures are lower and you get more snow. Southests parts of Finland can suffer from the lack of snow almost whole the winter. According to my cognitions I would say that we get normally something around 20 to 70 cm here east/pretty south. Or got. As to snow, recent years have been pretty poor. I've even heard that there weren't snow at all in the southest part of the country in the last year. Except the year before last year there were a real "snowstorm" on our corners. We got snow surely 100 to 150cm (and because our backyard is pretty space and plane snow drifted there. I estimate that the drift was finally something around 3m high. It was odd to watch out of a window when you saw more snow than sky. But this snow and drift didn't stay whole the winter).
I hope that we'll get snow in the future too. It lights a little when there are dark all around you and is much more comfort than rain and wet environment.
It's not even Thanksgiving yet, and I heard on the news that we were supposed to get up to 18 inches of snow tomorrow. Usually our bad snow months are January/February. Heavy snow its around a foot or so. We get lots of snow being right next to Lake Michigan. We get blizzard like storms. Nasty weather, where everyone can barely see out their windows type nasty.
It usually doesn't really snow here until about January. I'd say that most of the time if snows a couple inches. It's not really a snow until about 4 inches 'cause the grass sticks out if there's not at least 3 or 4 inches of snow. Every couple of years they have a snow day at school. They usually don't cancel school until about 8 inches that come down quickly or a really bad ice/snow mix. We've had flurries a couple of times already.
My uncle moved to Nashville years ago. He has always joked that they cancel school if the weather man says it might snow.
