Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 22 Jan 2017 to Tuesday 31 Jan 2017:

High pressure is likely to continue to dominate across the UK on Sunday, bringing rather cloudy skies across much of the north. However, southern counties will see generally colder and brighter conditions, though with a risk of frost and fog forming overnight too. Looking ahead into the next working week, more unsettled conditions may spread into the north and west which will bring some spells of rain at times here. The unsettled and at times windy conditions are likely to spread south and east through the week, which will bring milder conditions to most and outbreaks of rain at times across the country. The bulk of the rain is likely to be in the west.

UK Outlook for Wednesday 1 Feb 2017 to Wednesday 15 Feb 2017:

Looking ahead to the start of February the most likely scenario is that Atlantic low pressure systems will bring spells of wet and windy weather to all at times, though this will be interspersed with drier and brighter interludes. Temperatures will generally be around average for this time of year, though it will turn milder again at times. There is a possibility that an area of high pressure will become dominant again, towards the middle of February, bringing more settled conditions with the return of overnight frost and patches of fog. However, confidence regarding this detail is low.
