For most locations a continuing trend to more settled weather into the weekend as high pressure builds close to the southwest of the UK, though Scotland likely remaining in a more wet and windy regime with westerly winds. As such, the wettest weather likely across western high ground, mainly in Scotland and occasionally parts of Northern Ireland and northwest England. Settled conditions in the south with average temperatures and cloudy at times with some patchy light rain, mainly near western coasts and over hills. Clearer spells favoured the south and east but these also allowing potential for fog or frost overnight. The following week sees potential for high pressure to decline allowing a return to unsettled conditions and typically average temperatures, favouring the northwest for wettest and windiest conditions.

More likely to be unsettled compared to the preceding settled spell with bands of rain crossing the UK with brighter conditions and showers in between. The wettest and windiest conditions are most likely in the west and northwest. The chance of a colder spell of weather, with hazards such as snow and ice, does increase later in December and into the New Year period. However, on balance conditions are more likely to remain generally mild and wet.
