Weather Situation
A trough and cold front continue moving across the far northeast on Sunday. A ridge of high pressure will move into the west late Sunday and persist over much of southern SA through to mid-next week, as the associated high slowly drifts east across waters to the south. A trough and low pressure system may then develop near the WA border from late Wednesday.
