Yeah, looking at the first map you've provided, I see what you mean (and on a slightly off-note, I never noticed how wide the mountains in the west of North America actually are).

As for the temperature map, I did point out in that post that I was basing it entirely on latitude ("Here I've based temperature entirely on latitude. I haven't taken into account altitude or oceanic currents"), I was just wondering if the rough spacing of temperatures in relation to latitude were OK, before I started moving on to take things similar to the Gulf Stream or the effect of altitude into account

(And yeah, we don't have snow yet, even in Yorkshire. We had a little bit of snow, but it didn't settle. It probably won't turn up until maybe mid-January )
