Weather Situation

A ridge of high pressure extends from a high south of WA, across waters well south of SA. The high slowly moves eastwards to be centred over the Tasman Sea by Saturday afternoon, with further high pressure systems building well south of the Bight. A trough over inland WA is expected to move across western and northern SA on Sunday and into the new week. A cold front clips the southeast early next week.
