Updated at: 0201 on Sat 22 Jul 2017

UK forecast for the next 5 days

Showers for many this weekend. Drier early next week.

Today:

Heavy and thundery showers, most frequent in the southwest at first but spreading northeastwards. Sunny spells for many with the driest and sunniest weather across Northern Ireland and western Scotland. Cloudier for southern and eastern Scotland with outbreaks of rain.

Tonight:

There will be further outbreaks of showery rain overnight. However, towards the southwest it should turn mostly dry and clear spells here means it will turn a touch fresher.

Sunday:

Showers re-developing across England and Wales, these heavy and perhaps thundery. Cloudier with persistent rain across southeast Scotland and northeast England. Drier and brighter for western Scotland and Northern Ireland

Outlook for Monday to Wednesday:

Rain in the east gradually clearing on Monday, drier and brighter further west. Mostly fine on Tuesday with rain spreading from the west on Wednesday. Temperatures near normal.

Updated at: 0201 on Sat 22 Jul 2017

Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 27 Jul 2017 to Saturday 5 Aug 2017:

Some rather unsettled weather looks set to affect the UK with often cloudy conditions with heavy rain moving across the country at times. A mixture of sunny spells and showers between the heavier spells of rain looks likely. Temperatures will be cooler generally, especially in any rain or showers but some warmer spells also. The unsettled or changeable theme looks likely to remain through the end of July, with north-western areas seeing the heaviest rain and showers and stronger winds. South-eastern areas are likely to be drier through the period, however a more prolonged spell of settled weather looks unlikely at this point. Signals in early August look very weak however there is increasing confidence for a continuation of changeable weather influenced by the Atlantic.

Updated at: 1308 on Sat 22 Jul 2017

UK Outlook for Sunday 6 Aug 2017 to Sunday 20 Aug 2017:

Despite rather mixed or weak signals for this period, the most likely scenario is for a changeable Atlantic driven airflow across the UK. This is likely to bring showers or longer spells of rain, and chance of strong winds at times. Southern and eastern areas are most likely to see periods of more settled weather. Temperatures may also recover to some extent through August, particularly in the south, to average or perhaps above.
