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 Wednesday 26 Jul 2017 to Friday 4 Aug 2017:

Generally unsettled throughout the remainder of July and into the start of August with spells of rain and strong winds crossing the country from west to east. The rain will be heavy at times, particularly in the northwest and here there is also the chance of gales at times too. In between there will be some drier and brighter spells, however there will be also be a scattering of heavy showers, again these most frequent and heaviest in the northwest. The chance of any longer drier and more settled spells is limited and only the southeast of the country is likely to be drier overall. On the whole temperatures will be close to or slightly below normal for the time of year, with the coolest temperatures likely in the west.

UK Outlook for Saturday 5 Aug 2017 to Saturday 19 Aug 2017:

There is low confidence in the forecast during August. At first we are likely to see a continuation of changeable weather with further showers or longer spells of rain, accompanied by some spells of stronger winds. Southern and eastern parts will perhaps become drier and more settled at times. However, after a rather cool start to the month, temperatures are likely to recover and become closer to average or slightly above as we head through the month.
