People think that Northeast England has a lot of snow, but actually these days at low levels it's not that common - at least within the urban heat islands. I'd say where I live (90m above sea level, urban fringe) the majority of winters have only a day or so of lying snow, some winters there's hardly even any frost. So up to say 200m and it's a very different story - so often the low ground is just on the freezing level, just a little extra height and you're into heavy snow and with the wet air rising up the hills from the North Sea I do mean heavy.
