Planning Outlook

All mountain areas of Britain from Thursday 21st June 2018

High pressure builds from the west later this week to bring plenty of fair weather over the next week to 10 days. This weekend has a risk of patchy rain and low cloud for the north-western Highlands brought in on fresh westerly winds, otherwise it will be dry with many summits clear. Rather cool in the short term, but temperatures rising into next week, and eventually it may become widely hot and humid. By the end of June this may break into thunderstorms.
