These tropical plumes are very important for our weather, but they are chaotic. This pattern is new to me. The plumes are dragging down very cold air from Siberia and the Arctic. At the same time, the low pressure (warm, rising air) is bringing up the Gulf air for the East.
Unlike our confident friends gathering in Glasgow, I see a lot of uncertainties. My main prediction of it becoming colder is simply based on historic cycles, and a general lack of heat energy coming from the Pacific. I hope they have a record cold in Scotland, with lots of snow. Won't phase them at all.
