The main point to monitor is the high pressure system sat over the United Kingdom on this run. It will be this position that dictates whether mild or cold air floods in for Christmas. The current position suggests cold air trying to undercut the warm air, rising into the north Atlantic. You will also have cold air flooding down from the Arctic Circle with a direct approach to the United Kingdom. The Atlantic will also have two systems turbo charging warm air towards the United Kingdom but it is these two systems which will be driving the jet stream. This jet stream will then hit the low pressure system and be directed down south, before being able to rotate around and head east again into Africa. This would allow cold air to flood into the United Kingdom and Europe, with the High Pressure system sat where it is, or even further west.
