Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 11 Dec 2016 to Tuesday 20 Dec 2016:

Sunday will start generally dry and bright for most, but it is likely to turn wetter from the north-west later in the day as a frontal band arrives from the Atlantic. Into the following week, further periods of wet and windy weather are expected to move across the UK. The most unsettled conditions are likely across the north and west with drier and brighter weather for southern and eastern areas. By mid December there will probably be some longer, drier spells between the wet weather, perhaps heralding a change to something generally more settled. It will also be fairly mild initially but temperatures are likely to return closer to normal, although passing weather systems may raise them at times.

Updated at: 1516 on Tue 6 Dec 2016

UK Outlook for Wednesday 21 Dec 2016 to Wednesday 4 Jan 2017:

Whilst there is a good deal of uncertainty, it is most likely during this period 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. However, there will probably also be some milder, unsettled interludes too, and as we head into the New Year this may become more of a feature in our weather.
