Planning Outlook

All mountain areas of Britain from Friday 25th July 2014

Again very warm, sunny and little wind on Friday - but the risk of an isolated afternoon storm. Less warm from the west across Scotland on Saturday, when particularly in eastern Scotland the threat of thundery bursts of rain will be higher. Less hot next week. Through the first half of the week, low cloud will become extensive western mountains, mainly Scotland (though very little low cloud Sunday). From Monday a little rain from time to time, but this will amount to very little, particularly away from the W & NW Highlands.
