Planning Outlook

All mountain areas of Britain from Sunday 28th May 2017

Following Saturday's thundery breakdown, most areas will be dry into Sunday, and cooler than previous days. On Monday, there is a risk of further thundery rain extending from the south, although detail is uncertain. For the rest of the week, high pressure will be to the south & south-east, allowing some dry and bright days, but fronts will try and encroach from the Atlantic, bringing occasional rain to mainly western Scotland. A generally more unsettled pattern is likely to develop as the week progresses, with rain becoming more frequent, and winds strengthening at times.
