    UK forecast for the next 5 days

    Showers easing away leading to an unseasonably cold night.

    Sunday:

    After a cold start, largely fine for many with the best of the sunshine across northern and eastern parts. Thickening cloud brings rain to Northern Ireland and southwest Britain later.

    Issued at: 1700 on Sat 23 Aug 2014

    Outlook for the UK over the next 6-30 days

    UK Outlook for Thursday 28 Aug 2014 to Saturday 6 Sep 2014:

    Rather unsettled across much of the UK on Thursday, Friday and into the weekend with outbreaks of rain, heavy at times, interspersed with brighter and drier interludes. It will be windy at times in the northwest. However, conditions may become drier and brighter across southern parts through Friday, into the weekend and perhaps into the start of the new week. A northwest to southeast split is the most likely scenario through the rest of the period with the wettest weather likely to be in the northwest, where it will be windy at times, whilst the best of the drier and brighter interludes will be towards the southeast and possibly becoming lengthier with time. Temperatures will be near normal, but warm at times during the sunnier periods and towards the southeast.

    UK Outlook for Sunday 7 Sep 2014 to Sunday 21 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.
