Forecast Summary

  • Regional
  • UK 5 days
  • UK 6-30 days

Regional forecast for Wales

A bright and chilly start, turning cloudier later.

Today:

After a mainly dry, bright and locally chilly start cloud will thicken with some patchy rain possible across north Wales through the afternoon. Winds will be much lighter than on Tuesday and it will feel less cold. Maximum Temperature 15C.

Tonight:

Generally cloudy, although some clear spells likely for eastern areas. The cloud will be thick enough at times to produce the odd light spot of rain, mainly across western areas. Minimum Temperature 9C.

Thursday:

A breezy and generally cloudy day, but some brighter spells are possible at times. Occasional outbreaks of rain are likely for most, particularly across western coasts and hills. Maximum Temperature 17C.

Outlook for Friday to Sunday:

More persistent rain on Friday, clearing southeastwards with drier, brighter conditions and some sunny spells on Saturday following a chilly start. Cloudier and breezier Sunday with a little rain possible.

Issued at: 0500 on Wed 22 Oct 2014

UK forecast for the next 5 days

Wet and windy in north. Drier, but increasingly cloudy elsewhere.

Today:

A dry, bright and chilly start for many southern and eastern areas, though it will turn cloudier through the day. Rain and strengthening winds will return to Northern Ireland, Scotland and northern England, turning heavy at times over western hills.

Tonight:

Generally cloudy with a few clear spells in the southeast and occasional rain in the west, persistent in some northwestern areas. A milder night, but remaining windy in the north.

Thursday:

A generally breezy and cloudy day with some brighter spells in the south and east. Sporadic outbreaks of rain, mainly in the west, persistent in the northwest. Temperatures above normal.

Outlook for Friday to Sunday:

A band of rain will push southeast through Friday, clearing southeast England early Saturday. Then all parts brighter with occasional showers, more rain in the northwest later. Becoming very windy.

Issued at: 0500 on Wed 22 Oct 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 26 Oct 2014 to Tuesday 4 Nov 2014:

Showery and very windy across northern areas on Sunday and Monday, with a risk of severe gales for a time. Somewhat less windy further to the south, though with increasing amounts of cloud. Into the midweek period, a north-south split looks most probable, with windy and often unsettled conditions continuing in the north and somewhat quieter, drier weather in the south. Temperatures will generally be near normal, although feeling quite cold in the strong winds. Towards the end of October and into early November, the broad north-south split looks set to continue, with northern areas remaining changeable and at times unsettled. Further south, there are hints that pressure may start to rise, increasing the potential for more prolonged drier periods, but with a greater risk of overnight frost and fog.

UK Outlook for Wednesday 5 Nov 2014 to Wednesday 19 Nov 2014:

The main signal is for a continuation of a north-south split during the first half of November. During this period, the generally westerly flow is likely to bring spells of wet and windy weather, interspersed with drier intervals. These should mostly affect northern and some western areas, but perhaps reaching other areas as well at times. However southern and some eastern areas will probably see more in the way of the drier and settled conditions increasing the likelihood of seeing some sunshine, but also the risk of frost, mist and fog overnight, the latter of which could be slow to clear. Daytime temperatures are likely to be near or a little above normal, although feeling cooler during any wet and windy spells.
