Planning Outlook

All mountain areas of Britain from Sunday 6th September 2015

Turning warmer into next week, and particularly on western mountains from Tuesday, sunnier. However, the weather may well begin to break down to wetter conditions toward next weekend as the area of high pressure, currently just west of Britain, transfers to eastern Scandinavia.
