Areas of rain, some heavy, are likely on the mountains on Friday and over the weekend. Generally the rain patchy on Friday, but there may be areas of heavy thundery rain over the weekend, although on Sunday there is considerable uncertainty as to how quickly the rain becomes confined to Scotland as it clears from the south. It may also be windy on Sunday.
