Planning Outlook

Relatively low temperatures on the mountains much of next week; particularly on the Scottish highlands where higher tops will frequently be near freezing point. Showers, some heavy and thundery, giving hail and on higher tops snow, will be widespread, particularly in the afternoons, when in some areas they will merge to give a few hours of precipitation.
