UK forecast for the next 5 days

Headline:

Wet and breezy tomorrow.

Rain and wind in the west spreading eastwards, staying heavy in north Wales and northwest England, but clearing to showers in Northern Ireland/Scotland. Becoming dry and mild further South.

Updated: 15:13 on Mon 23 Oct 2017 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 28 Oct 2017 to Monday 6 Nov 2017:

The weekend will be mainly dry and bright in the south and west but cloudier with rain or showers in the north and east. It will be breezy, with gales possible in the north. Temperatures will be lower than this week, perhaps bringing overnight frost in places. Next week the weather is likely to become changeable again and sometimes windy, with rain bands crossing the country, interspersed by brighter, showery weather. The north is likely to get the wettest and windiest weather. It will probably become a good deal colder than of late, bringing an increased risk of early morning frosts across the country. There is also a chance of snow over high ground in Scotland, and perhaps at lower levels in the far north as the wind turns northerly.

UK Outlook for Tuesday 7 Nov 2017 to Tuesday 21 Nov 2017:

There is an increasing chance that the weather will become more settled during this period, especially across southern parts of the British Isles. As a result frost and fog will become more likely. The north may continue to have more changeable weather though. Temperatures are most likely to be near average, although probably below normal in some of the more settled spells, especially where any overnight fog proves slow to clear.
