UK forecast for the next 5 days

Headline:

Warm with sunny spells. Rain in the northwest later.

Friday:

Rain will push into south Wales and the Midlands, leaving western Scotland and Northern Ireland with late sunshine. The southeast will become hot, triggering hit-and-miss thunderstorms later.

Mostly dry and very warm. Becoming hot and humid in the south and east. Often cloudy and breezy in the northwest, with some rain or drizzle at times.

Updated: 15:56 on Thu 19 Jul 2018 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 24 Jul 2018 to Thursday 2 Aug 2018:

On Tuesday and Wednesday the northwest of the UK is likely to see cloudier conditions with some rain and drizzle at times, especially across western hills. Elsewhere it should be largely dry with sunny spells and light winds, chiefly across the east and southeast, with perhaps the odd thunderstorm. Looking further ahead a west-east split in conditions is likely to develop, with eastern and southeastern areas being drier, more settled, very warm and increasingly humid, but always with the risk of isolated showers or thunderstorms. Further west it may be more changeable and breezy with some outbreaks of rain or showers, but also some drier interludes. Temperatures nearer normal in the west, but generally warm elsewhere, with hot or very hot conditions at times in the east and southeast.

UK Outlook for Friday 3 Aug 2018 to Friday 17 Aug 2018:

Throughout this period it seems most likely that the weather pattern will very slowly evolve. The west of the UK is likely to see more in the way of breezier, cloudier conditions with some rain or showers at times, with these occasionally affecting other areas. Elsewhere, especially further east, drier and more settled weather is expected to dominate, although with the ongoing risk of a few heavy showers or thunderstorms breaking out at times. Temperatures remaining above average for most, with the potential for further spells of very warm or hot conditions, and possibly very hot at times in the south and east. Temperatures are likely to be often nearer normal in the west and northwest.
