Weather Situation
A weak ridge of high pressure across the south of SA will weaken further during Saturday as a trough and cold front cross the Bight. The trough will move across the state on Sunday before interacting with a tropical low over central Australia early next week. The low and trough are then expected to remain slow moving across northern SA next week.
