Starting mainly unsettled, with showers or longer spells of rain for many parts of the UK. It will also be quite windy, especially towards the north and west. It will be mild, although the strong winds will make it feel rather cold. High pressure then looks like building close to or over the UK through early December. This will result in drier but also probably generally slightly cooler conditions, and increase the risk of overnight frost and fog. The largely dry, settled theme is likely to be punctuated by brief unsettled and milder spells though, with areas of low pressure crossing the UK, bringing some spells of wind and rain. Temperatures overall generally near average, but rather cold where any fog persists.

The start of this period looks like being largely settled, with high pressure close to if not over the UK. However, towards mid-December, there are signs that it will become less settled with west or northwesterly types preferred, These will bring some wetter and windier spells with a risk of some snow, especially for hills in the north. These conditions may prevail into late December, although drier, more settled spells may also affect the UK at times, these probably more likely towards the south. Temperatures generally close to average through the period.
