- A high pressure system centred east of Tasmania extends a ridge over SA. The ridge moves eastwards ahead of a cold front and trough moving into the far west this evening and then across the west and south of SA during Wednesday. The trough will clear the northeast during Thursday whilst a high pressure ridge moves across waters well to the south. A low pressure trough is expected to develop over the far west of SA on Friday then move slowly eastwards over the weekend.
