On Monday the high moves into the Tasman Sea directing a northerly airstream over SA, ahead of another trough expected to move into the west and across the south on Tuesday. The trough moves into the eastern states on Wednesday as another high pressure system moves into waters south of the Bight to reach the Tasman Sea on Thursday whilst still maintaining a ridge over southern SA.
