Planning Outlook
High pressure in the vicinity of the British Isles will bring extensive fine weather over the next week - perhaps much longer. Winds frequently light and mountains often free of low cloud. Generally warm, although cold air over the weekend and early next week will bring summits in Scotland below freezing point and widespread frost to lowland valleys at night. Very dry conditions underfoot will extend to almost all mountain areas with fire risk becoming very significant indeed.
