UK forecast for the next 5 days

Showery rain clearing south overnight. Sunshine and showers tomorrow.

Less chilly than recent nights for southern parts with cloud and outbreaks of showery rain, possibly heavy at times, becoming confined to the southeast. Clearer and cooler conditions in the north with scattered showers, mainly in the far north.

Friday:

Cloud and showery outbreaks of rain across southeastern areas, clearing in the morning. Sunny spells and a few showers following, most frequent in the northeast. Another cool day.

Issued at: 1700 on Thu 21 Aug 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 26 Aug 2014 to Thursday 4 Sep 2014:

Any lingering rain in the far east may clear on Tuesday, there will then be spells of rain or showers through the middle of next week as a mobile westerly pattern becomes established. Winds could be locally strong in the north and west, with a risk of gales. It then stays rather unsettled through the period with scattered showers or longer spells of rain, interspersed with brighter spells. The wettest weather is likely to be in the northwest with stronger winds also likely at times, whilst the best of the drier and brighter interludes will be towards the southeast. It will stay cool in the wind and rain, although temperatures will be close to or slightly below normal, but warm at times during any drier spells and towards the southeast.

UK Outlook for Friday 5 Sep 2014 to Friday 19 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.
