Discussion: Snowstorm

That sounds like very impressive numbers - was it fairly localised or more widespread? Sometimes in this sort of situation areas near east coasts can get a lot of snow because a cold easterly picks up low-level moisture crossing the (relatively) warm ocean and then dumps it on the first bit of topography it hits on the other side, but I wouldn't have thought Uppsala was hilly enough for that.

Southeast shores of some of the Great Lakes get masses of snow from this, as does the northwest side of Japan.
