Outlook for the UK over the next 6-30 days

UK Outlook for Monday 23 Jan 2017 to Wednesday 1 Feb 2017:

High pressure is likely to continue to dominate across the UK on Monday and Tuesday, with mostly dry and settled conditions expected, aside from in the far north-west where rain and strong winds are possible. Temperatures will be mostly either around average or a little colder. Looking further ahead, more unsettled conditions are expected to slowly spread further into the north and west bringing spells of rain and strong winds, although it will be more settled further south and east. The unsettled and at times windy conditions are expected to continue to slowly spread south and east through the period, eventually bringing milder conditions to most and outbreaks of rain at times across the country, this likely heavier further west and lighter and less frequent further east.

UK Outlook for Thursday 2 Feb 2017 to Thursday 16 Feb 2017:

Looking ahead to the start of February confidence is fairly low. However, 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 with occasional milder spells. 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.
