Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 29 Nov 2017 to Friday 8 Dec 2017:

Wednesday and Thursday will see a mixture of sunny spells and showers. The showers mainly affecting exposed northern and eastern parts, especially the North Sea coasts, but not exclusively. The showers will be heavy at times and turning wintry over higher ground. Windy, with gales down the east coast on Wednesday. Similar conditions look likely to persist into Friday and the weekend, with showers continuing to affect eastern parts, but drier with plenty of sunshine elsewhere. The showers may be wintry across all parts, but any snow accumulations most likely over higher ground, but perhaps to some lower levels in the north. Staying rather cold, with temperatures below the average into early December. However, there is a chance of less cold, cloudier conditions spreading southeastwards, with some rain at times.

UK Outlook for Saturday 9 Dec 2017 to Saturday 23 Dec 2017:

During this period of December, it looks likely that the cold conditions may persist across the United Kingdom, with a generally blocked and slow moving weather patterns, which brings more uncertainty than normal into the forecast. We are likely to see a mixture of sunshine and showers for many, with the showers turning increasingly wintry over the hills, but not exclusively. Temperatures will probably be below the average through to mid-December. However, there is the chance of periods of milder, wetter and windier weather, with increased amounts of rainfall, during the middle of the month, especially in the west. This could see temperatures recover closer to the average.
