Substantially dry on many mountains but areas of frequent showers (hail and snow), mainly NW and W Highlands (where wind close to gale on Saturday) and north and west Wales. Some uncertainty for Sunday afternoon with threat of rain setting in on many western mountains - ahead of a less cold but often windy and wet few days.
