The ridge will move eastwards today ahead of a cold front and trough expected to move across the west and south of SA during Wednesday. The trough will clear the northeast during Thursday and a high pressure ridge will move across waters well to the south. A low pressure trough will develop over the far west of SA on Friday then move eastwards next weekend.
