The persistent rain will soon clear through the evening. Turning drier thereafter but staying rather windy with some clear spells and the chance of an isolated shower. Minimum Temperature 7C.

Updated at: 0345 on Wed 27 May 2015

UK forecast for the next 5 days

Rain spreading east through the day.

Today:

Showery across the far northwest but largely dry elsewhere through the morning with sunny spells, particularly in the south. Through the afternoon, rain and stronger winds will push eastwards, affecting many central and western areas by evening.

Tonight:

Rain will continue to move eastwards, clearing by around midnight. Staying windy with some clear spells but also scattered showers, mainly in the north and west. Chilly in the north.

Thursday:

Staying showery in the northwest with thunder and hail possible but with much fewer showers elsewhere with more sunshine. Windy with gales possible in the north. Feeling cool.

Updated at: 0345 on Wed 27 May 2015

Outlook for the UK over the next 6-30 days

UK Outlook for Monday 1 Jun 2015 to Wednesday 10 Jun 2015:

Rather unsettled conditions at first with spells of rain interspersed by drier, brighter and more showery interludes. It may be rather windy, particularly in the northwest, with the bulk of the rainfall also here. Southern and eastern areas look best placed for the driest, brightest weather. Temperatures are likely to be below average across the country, but particularly in the northwest. By midweek, unsettled conditions are considered likely to continue in the northwest, with slightly below average temperatures, but more settled, warmer, conditions may start to build in the south. Towards the end of the week these warmer, more settled conditions look likely to spread north to most of the country although perhaps with a risk of showers in the south.

UK Outlook for Thursday 11 Jun 2015 to Thursday 25 Jun 2015:

There is some uncertainty in the likely weather type through this period, however high pressure will have become established to the north of the UK. This would lead to drier, warmer conditions for many, these perhaps most prolonged across the north, but it may also allow some more unsettled, perhaps thundery weather to move up from continental Europe and affect the south of the UK. This trend looks like it may continue into the third week of June with drier than average conditions in the north, however some unsettled spells are also likely to push in from the west at times, as well some thundery outbreaks also coming up from the south.
