UK forecast for the next 5 days

Dry, not as cold but some dense fog forming.

This Evening and Tonight:

Low cloud and fog will become widespread across much of England and parts of Wales but it will be clearer across Scotland with a frost and some fog patches. Breezier with a little light rain across Northern Ireland.

Tuesday:

Wet and windy weather will spread across Northern Ireland and western Scotland, otherwise it will be dry across the UK. Cloudier though with some persistent fog and a chilly feel.

Milder for all with spells of wet and windy weather; the heaviest rain across the northwest of the UK. A drier spell of weather for most on Thursday though.

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 10 Dec 2016 to Monday 19 Dec 2016:

It is likely to be cloudy with spells of rain across southern and south-eastern parts of the UK on Saturday. The rest of the UK should be brighter with blustery showers. During the rest of the weekend and 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 should be some longer, drier spells between the wet weather, with a gradual change to something a little more settled. It will also be fairly mild initially but temperatures are likely to return closer to normal, with an increasing risk of overnight frost.

Updated at: 1226 on Mon 5 Dec 2016

UK Outlook for Tuesday 20 Dec 2016 to Tuesday 3 Jan 2017:

Whilst there is a good deal of uncertainty, it is most likely that high pressure is going to become more dominant through the end of December, and so the weather should be more settled across 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. As we head into the New Year there is the potential for the weather to become more unsettled again.
