What is it with you townies? I once had neighbours who moved out of London to Northants and were convinced they'd need a 4x4 as they were bound to be snowed in every winter as this was the countryside.
However, in fairness, Scotland does rather tend to have its own weather systems. Edinburgh and the Firth of Forth generally seems to suffer with mist and fog fairly regularly, especially through winter and spring, when the weather elsewhere is pretty good. That said, I don't think you'll find any great difference to the number of VFR flyable days to the south east, just Scottish VFR may be cloudier, colder and wetter than you're used too.
