Outlook for the UK over the next 6-30 days

UK Outlook for Monday 1 May 2017 to Wednesday 10 May 2017:

Bank Holiday Monday currently looks likely to be rather unsettled in the south, with some showery outbreaks of rain moving across the UK. However there will be brighter spells in-between, and in the brightness it should feel fairly pleasant, most likely in the north. There may well also be some showers on Tuesday, and to a much lesser extent on Wednesday, but on the whole Wednesday is likely to be dry with some sunshine for many. Temperatures early next week are expected to be around average for early May. Then from Thursday onwards we are likely to see high pressure dominate, with largely dry and settled weather prevailing, with increasing amounts of sunshine. The settled weather is also likely to bring temperatures slightly above average, especially during the sunnier interludes.

UK Outlook for Thursday 11 May 2017 to Thursday 25 May 2017:

Heading into the middle of May, and on balance the dry and settled weather is likely to continue to dominate. There may however be some occasional wetter interludes, with western areas more likely to see these. Temperatures are likely to remain above average, and possibly becoming very warm at times at first, before perhaps returning to nearer normal towards the end of the period.
