A low pressure trough enters the west of the State and is expected to move across the south on Tuesday. A secondary high pressure system moves into waters south of the Bight on Wednesday, tracking eastwards to reach the Tasman Sea on Thursday, maintaining a ridge over southern SA into Friday as another high pressure ridge extends in from the west.
