Turning more generally changeable from the end of the week and through the remainder of the period. The northwest tending to see spells of rain or showers with some drier, brighter interludes.

UK Outlook for Saturday 10 Jun 2017 to Saturday 24 Jun 2017:

Confidence is currently low through this period, though we are more likely to see changeable conditions continue through the early part of June. More settled weather may begin to dominate for a time towards the middle of the month, mainly in the south, bringing some drier and brighter weather. 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. By the latter part of the month, there is a possibility of more unsettled conditions developing once more, with spells of rain at times, and temperatures returning closer to average.
