Whilst there may be a scattering of showers, many places will have a dry day with some decent periods of sunshine. Despite this, it is going to be cool again. Maximum Temperature 18C.

Tonight:

It should be a generally dry night with largely clear skies. This means it will again be unseasonably chilly for many. Minimum Temperature 4C.

UK forecast for the next 5 days

Dry for many but some showers. Cool again.

Today:

Another cool day. Many places staying dry with a good deal of sunshine. Whilst there will be some scattered showers, these should be lighter and less frequent than Tuesday. Cloud and rain will spread into northwest Scotland during the afternoon.

Tonight:

Cloud and outbreaks of rain gradually spreading southeastwards across Scotland and Northern Ireland reaching northern England during the early hours. Mostly dry and cool with prolonged clear periods further south.

Thursday:

Cloud and showery rain spreading southwards, but staying largely dry and bright in the south and east. Brighter again in the north later. Cool again.

Showery outbreaks of rain for southern parts on Friday, clearer conditions extending from the north with some showers. Mostly dry over the weekend but rain arriving from the west later.

Issued at: 0500 on Wed 20 Aug 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 24 Aug 2014 to Tuesday 2 Sep 2014:

After a cold and clear start for many on Sunday, cloud and rain in the southwest will spread northeast to affect most places by the end of the day. Temperatures will recover back to average values for August thanks to the change in wind direction, but freshening winds in the west will make it feel cooler. Unsettled through next week, and likely beyond, with showers or longer spells of rain. The wettest weather should be in the northwest where there could be strong winds at times, whilst the best of the drier and brighter interludes will be towards the southeast. Temperatures will generally be around normal, perhaps locally warm at times in the southeast, but still feeling cool in the wind and rain.

UK Outlook for Tuesday 2 Sep 2014 to Tuesday 16 Sep 2014:

Current signals continue to suggest a broadly changeable spell of weather. As such, most regions can expect to see spells of fine weather, with some warm sunshine at times. However, these spells will then be interspersed with more unsettled conditions bringing showery outbreaks and perhaps more prolonged spells of rain. Northern and western parts are then likely to see the most frequent bouts of unsettled weather, whilst southern and eastern parts are likely to see the most frequent and prolonged fine and dry spells. Daytime temperatures, meanwhile, are likely to be warm during the fine spells and near or below average during unsettled weather.
