Definitely true whenever there is apbnormal cold in Scandinavia there is always a chance the UK could tap into it under right synoptic as you say. Long range weather forecasting is a fickle business, could anyone share what there thoughts were for last winter? I do think there will be a southerly tracking jet, with the jet being rebounded south - by cold Atlantic & extensive HP over northern latitudes, so a wet winter for the med IMO. The Scottish mountains/hills will do remarkably well. I will be very startled if UK does not have at least 1 notable cold spell the telecommunications are a total reverse to last year, so there are reasons to be hopeful.
