Planning Outlook
Less settled this weekend and into next week. Rain will not be extensive, but in some areas persistent for a few hours and some heavy, possibly thundery bursts - although particularly by Sunday local detail is as yet uncertain. Temperature levels will drop from the north, indeed early next week overnight and mornings higher slopes will be below freezing point Scottish Highlands, and further frosts are likely in valleys.
