Well I suppose there might be an indirect link. I think 1000 feet in the SW gives about the same winter temps as a few hundred feet in the Midlands, and my altitude of ~0 feet here in N Suffolk. Though Haytor will in general be much wetter!! But if the wind is from the west, Haytor is colder due to the altitude, whilst if the wind is from the east, Suffolk is colder, and we get first option on the snow if the air mass is cold enough.

If it is the case that SSW induces easterly winds, then we would stand to benefit more than Haytor.
