Updated: 15:00 on Mon 20 Aug 2018 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Aug 2018 to Monday 3 Sep 2018:

This weekend,, many places will have sunshine and showers. These showers will be heavy at times, with a risk of hail and thunder particularly in the north, with sunnier spells in the southeast. It will be windy at times, and some more persistent rain may arrive from the west later on Sunday. For Bank Holiday Monday, it is most likely to be unsettled in the northwest, with longer spells of rain and some strong winds. Drier and brighter conditions are generally likely in the south and east. This northwest, southeast split is then quite likely to continue. Temperatures will start rather cool, but they will recover to around the seasonal average, with perhaps warmer conditions at times in the southeast. Drier weather may become more widely established into early September.

UK Outlook for Tuesday 4 Sep 2018 to Tuesday 18 Sep 2018:

For the start of September it looks likely that the weather pattern will only change slowly. Areas of high pressure and associated settled weather will probably increasingly dominate, with some longer dry spells, particularly for northwestern areas compared to much of August. However there are also likely to be some more changeable weather at times in the north and northwest, with outbreaks of rain and strong winds, with these conditions perhaps extending southeastwards at times. Temperatures by day are likely to be generally warmer than average, especially for the southeastern half of the UK but generally nearer the seasonal average further northwest, and there will be an increasing chance of chillier nights anywhere, as would be expected going further into September.
