High pressure is likely to dominate across the UK through to the end of the year, centred to the west or northwest over the North Atlantic. This will likely maintain relatively settled conditions at first, but with a little light rain or drizzle in places and a few showers possible along some coasts exposed to the northerly wind. Around the turn of the year, high pressure is likely to shift a little farther away from the UK, allowing a greater chance of more changeable conditions to develop. This will bring an increased risk of some rain or showers at times which, with cold air close to the UK, may bring some wintry hazards to some places. Temperatures will probably be near or slightly below average for this period overall.

Whilst confidence in details is low, high pressure will probably sit close to the UK initially, with periods of relatively settled weather interspersed with more changeable conditions. Temperatures will likely be near or slightly below average during this time, with an enhanced risk of wintry hazards affecting some parts at times. 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.
