Mild, rather cloudy with rain from the northwest later.

A weakening band of rain will slowly edge southwards overnight, bringing increasingly patchy rain and hill fog to most parts. The south-westerly breeze will lead to another mild night. Minimum Temperature 8 °C.

UK forecast for the next 5 days

Rain slowly edging southeast. Colder, windier and clear conditions following.

Outbreaks of rain in the north and west. Some early hill fog and low cloud in the east and southeast. Otherwise, mainly dry with a mixture of cloud and brighter spells. It'll be another mild day for most.

Tonight:

Rain over Northern Ireland and Scotland giving way to clearer skies and showers. Rain over Wales and northern England sinking south-eastwards. A mild night for much of England and Wales.

Saturday:

Outbreaks of locally heavy rain across Wales and southern UK will slowly clear south-east later. Brighter elsewhere, but windy with showers in the north-west. Less mild in the north.

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 13 Dec 2016 to Thursday 22 Dec 2016:

It'll be dry and bright for most, but patchy overnight frost and fog are likely in the southeast. Through the week periods of wet and windy weather are expected to move across the UK from the west. 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. By mid December there'll probably be some longer, drier spells between the wet weather, perhaps heralding a change to something generally more settled. It'll be fairly mild initially but temperatures are likely to return closer to normal, although passing weather systems may raise them at times.

Updated at: 1140 on Thu 8 Dec 2016

UK Outlook for Friday 23 Dec 2016 to Friday 6 Jan 2017:

Whilst there is a good deal of uncertainty for this period, it is most likely that more settled conditions may dominate associated with high pressure affecting the UK. If the pressure does build, then we can expect drier than average conditions for most areas with lighter winds. Temperatures are also then likely to be below average with an increased risk of frost and fog, especially where skies remain clear overnight. There will probably also be some milder, unsettled interludes though, and as we head into the New Year this may become more of a feature in our weather, with the greatest likelihood of changeable conditions in the northwest, giving rain here at times.
