Weather Situation
A ridge of high pressure persists over southern parts of SA for much of the coming week. A trough about the north of the state will move south and deepen over the weekend, before pushing into the far northeast on Monday as the high centre moves into the Bight. Most of the state will be dominated by the ridge of high pressure on Tuesday, but is forecast to weaken as another trough enters from the west.
