Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 14 Dec 2016 to Friday 23 Dec 2016:

As we move through next week we are mostly likely to see a north-west to south-east split developing. During this time periods of wet and windy weather are expected to approach the UK from the west, however their eastward progression at this stage is fairly uncertain. In this type of scenario the most unsettled conditions are likely across the north and west, with drier and brighter weather for southern and eastern areas. It'll be windy at times, with the possibility of gales in the west and northwest, but it will be much less windy further south and east. It'll generally be mild with temperatures above average, however, in between weather systems temperatures will return closer to normal.

UK Outlook for Saturday 24 Dec 2016 to Saturday 7 Jan 2017:

There is a good deal of uncertainty for this period as the UK remains in a battleground between higher pressure across the near continent and lower pressure in the Atlantic. The exact orientation of these will dictate conditions across the country. Currently western parts are most likely to see outbreaks of rain at times, along with relatively mild conditions, whilst eastern areas will see drier and perhaps colder conditions. There will probably also be some milder, unsettled interludes though, especially into early January, with the greatest likelihood of changeable conditions in the northwest, giving rain here at times.
