Weather Situation
A high pressure system centred in the Tasman Sea extends a ridge over SA. The ridge moves eastwards ahead of a cold front and trough moving across the west and south of SA today. 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.
