    UK forecast for the next 5 days

    A chilly night, sunshine and isolated showers tomorrow.

    This Evening and Tonight:

    Isolated showers are likely to continue throughout the night, mainly for windward coastal areas. However most places will have a dry and increasingly clear night, along with the wind gradually easing, this will lead to it becoming rather chilly.

    Saturday:

    A generally fine and dry day, with sunny periods. However showers will continue to affect some central and eastern areas, where they could be heavy with thunder, before easing later.

    Outlook for the UK over the next 6-30 days

    UK Outlook for Wednesday 27 Aug 2014 to Friday 5 Sep 2014:

    Rather unsettled in the south for the latter part of next week, whilst northern areas will generally see drier and brighter weather. A quieter start to next weekend, though the general trend is for more changeable conditions later with heaviest and most persistent rain in the west, 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. Wettest weather is likely to be in the northwest, 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 drier spells and towards the southeast.

    UK Outlook for Saturday 6 Sep 2014 to Saturday 20 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.
