A cold and frosty start is expected on Tuesday, with some patchy freezing fog in places, which may be slow to clear. Cloud will increase from the west, then later rain for western parts. This may fall as snow at first across Scotland and the Highlands. Following a brief settled spell, further fontal systems are expected to move in from the west, more likely to bring rain and breezy conditions for much of the UK, especially northern and western parts. Towards the end of the period there are signs for more settled weather becoming amplified across the south of the UK. Temperatures will be close to or below average on Tuesday, then rising above average where frontal systems move in from the west.

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.
