High pressure is likely to be centred to the west or northwest over the North Atlantic through this period with low pressure to the east. Slowly evolving weather patterns are therefore most probable through this time. However, around the turn of the year, an area of low pressure may move through the North Sea bringing a period of wetter and windier weather, especially to the north. With cold air close to the UK, some wintry hazards are possible in places. Into January more settled conditions with colder and drier than average conditions are most probable. There will however be some periods of rain or showers and windier spells. Temperatures will probably be below average for this period overall and so wintry hazards remain a possibility in places.

Whilst confidence in details is low, high pressure will probably remain close to the UK initially, leading to slowly evolving weather patterns. Periods of relatively settled weather interspersed with more changeable interludes are likely, as are some spells of showers, especially around coastal areas. Temperatures will likely recover a little to be near to or slightly below average during this time, but an enhanced risk of wintry hazards affecting some parts at times remains. Later in the period, a transition to more widely changeable or unsettled conditions is possible, with a corresponding shift to near or slightly above average temperatures.
