Regional Forecast for Wales

Headline:

Bright start in the east. Generally turning cloudy and wet.

Tonight:

It will remain wet overnight across parts of the east with further outbreaks of rain, accompanied by hill fog. However, western areas should become drier and clearer with fog patches. Minimum temperature 13 °C.

Monday:

Patchy rain and hill fog will largely clear in the east, as will local fog patches in the west, to leave a mostly dry day on Monday. Some bright spells. Maximum temperature 17 °C.

Outlook for Tuesday to Thursday:

Tuesday will be brighter, but with a few showers. It will turn windy on Wednesday with rain arriving from the west. Thursday looks mostly dry and bright, but fresher.

Updated: 06:06 on Sun 24 Sep 2017 BST

UK forecast for the next 5 days

Headline:

Patchy rain moving into the west. Sunny in the east.

Today:

A band of cloud and patchy rain, occasionally heavy, will move across western parts during the day. By contrast, it will be a dry day across the east where it will feel pleasantly warm in any sunshine.

Tonight:

A cloudy night across central parts with patchy rain. Drier elsewhere with clearer skies under which some fog may form. A chilly and foggy night for Northern Ireland.

Monday:

A murky start for many and foggy across parts of Northern Ireland. Rain continuing to effect central parts. Becoming drier with some sunny spells developing later. Warm in the east.

Outlook for Tuesday to Thursday:

Early fog clearing on Tuesday with a few showers later, but dry for most. Turning wet and windy from the west by mid-week. Brighter and fresher on Thursday.

Updated: 06:08 on Sun 24 Sep 2017 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 28 Sep 2017 to Saturday 7 Oct 2017:

Thursday will be a changeable day as a band of rain, locally heavy, pushes east across the country, with the wet weather accompanied by strengthening winds. Brighter, fresher but showery conditions will follow from the west. Showers will be heaviest and most frequent in the northwest whilst it remains drier towards the southeast. Further wind and rain is likely to reach western areas by the end of the week and towards the weekend. From next weekend, it is likely to turn increasing unsettled for all with spells of rain, locally heavy, spreading east. It will be windy with the risk of gales in places, particularly across coastal areas. Temperatures will be around average for the time of year.

UK Outlook for Sunday 8 Oct 2017 to Sunday 22 Oct 2017:

More unsettled weather will continue across the country by the second week in October, most especially in the north and west. This will bring an increased likelihood of gales or severe gales as well as heavier rain across many parts. By mid October, confidence in the forecast reduces, however it may remain generally unsettled with occasional drier and brighter spells, particularly in the east and southeast. On the whole, temperatures will be close to or slightly warmer than normal, but in any settled spells there could be chilly nights, with an increased risk of mist, fog and frost, especially in the north.
