Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 28 May 2017 to Tuesday 6 Jun 2017:

A very uncertain period, but the more likely scenario is for rather mixed conditions during the Bank Holiday, with showery outbreaks of rain, perhaps heavy and thundery, but also some brighter spells. Temperatures are likely to be down compared to earlier on in the weekend, although it should stay rather warm and humid, especially in the southeast. Meanwhile, it will probably be cooler and fresher in the north and west, where we may see windier conditions. Into next week, we will generally see a mixture of sunshine and showers, particularly across the northwest. However, we may hold on to drier, brighter and perhaps warmer conditions in the far southeast, although some thundery showers are possible.

UK Outlook for Wednesday 7 Jun 2017 to Wednesday 21 Jun 2017:

Confidence is currently low through this period, but more settled weather may begin to dominate, bringing drier and brighter weather for many. Temperatures are likely to be close to normal at first, but may become generally warm, perhaps locally very warm for a time during mid June. Towards the latter part of June, there is a possibility of more unsettled conditions developing, with spells of rain at times, and temperatures returning closer to average.
