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 and cold front will move across the south on Sunday. A tropical low pressure system centred over the southeast of the NT extends a trough into the northeast of SA. The low and trough are expected to remain slow-moving next week and another ridge will extend across waters to the south of SA.
