On Monday, low pressure will continue to bring rain and showers for many, wintry across northern Scotland, and fairly windy at first in the east. However any wet and windy weather will ease as a ridge of high pressure moves in from the west overnight Monday and into Tuesday. This will bring drier and more settled weather for all, but also a risk of fog for some on Tuesday morning which could be slow to clear. Low pressure systems are then expected to resume moving in from the Atlantic from Wednesday, tracking close to, or across northern and western parts of the UK, perhaps resulting in more wet and windy weather here. Southern and eastern areas drier, but still could see rain at times. Temperatures for most places above average.

Settled weather is signalled to be most likely at first, at least across the south. However, towards mid-December, there are signs that the weather will become less settled again, with west or northwesterly types preferred. These will bring some wetter and windier spells with a risk of some snow, especially across northern hills. These conditions may prevail into late December, although drier, more settled spells may also affect the UK at times, again these probably more likely towards the south. Temperatures generally close to average through the period, or slightly above in areas which are wet and windy.
