Planning Outlook
Extensively dry with cloud widely confined above the mountains this weekend, although mainly Saturday in Scotland, showers and on western mountains areas of low cloud. Relatively chilly on the west and NW Highlands, but otherwise fairly normal temperatures for early August. Very complicated early next week; areas of rain will drift slowly across central and northern Britain, but the distribution of rain (and associated low cloud) very uncertain. Probably very little rain across Wales. Despite some rain (mainly in Scotland), away from the W & NW Highlands terrain remains exceptionally dry 'tinder dry'.
