Outlook for the UK over the next 6-30 days

UK Outlook for Friday 29 Sep 2017 to Sunday 8 Oct 2017:

On Friday, strong winds and coastal gales are likely to affect Northern Ireland and western Scotland. A band of rain and strong winds may well move across the whole UK including some heavy bursts. Further wind and rain is likely to reach western areas over the weekend. The weather in the following week is likely to stay rather unsettled for all with spells of rain, locally heavy, spreading east, and brighter showery weather following along behind. It will be windy with the risk of gales in places, particularly across western coasts. Temperatures will be around average for the time of year, with brief warmer or cooler interludes. The changeable weather means that night frosts are quite unlikely, except in the mountains of Scotland and Northern Ireland.

UK Outlook for Monday 9 Oct 2017 to Monday 23 Oct 2017:

Changeable weather is likely to continue across the country in the second week in October, with wind and rain at times, especially in the north and west. This will bring an increased likelihood of gales as well as heavier rain across some parts. By mid October, confidence in the forecast reduces, but drier and brighter spells could become more prolonged, though it may well remain changeable, On the whole, temperatures are expected to be close to normal for the time of year, but in any settled spells there could be chilly nights, with an increased risk of mist, fog and frost, especially in the north.
