Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 26 Aug 2018 to Tuesday 4 Sep 2018:

After a cold and dry start on Sunday, cloud and rain is likely to spread east into western areas later in the day. For Bank Holiday Monday, the rain is likely to gradually continue south and east, with drier and brighter conditions following. Temperatures should be around the seasonal average. The middle part of the week is likely to see a north-south split in the weather. Northern areas will generally be more changeable with some rain or showers at times, but it is likely to become more settled in the south with warmer temperatures. Drier and warmer weather may become more widely established into early September, as high pressure starts to build in from the south.

UK Outlook for Wednesday 5 Sep 2018 to Wednesday 19 Sep 2018:

Through the beginning and middle part of September, there is an increasing chance that much of the UK will see a good deal of dry, warm and settled weather. Northern and western areas could occasionally have wet and windy spells towards the middle part of the month, but these should be short-lived. Temperatures are likely to be generally warm across the UK, with a chance of very warm conditions developing in the south.
