Weather Situation
A high pressure system centred over the Tasman Sea extends a ridge over eastern SA, while a low pressure system and associated trough move into the far west. The low will move across the state on Monday and out over the eastern states by late Tuesday, as another high moves in from the west to be over SA on Wednesday. A second trough approaches the southwest during Thursday afternoon.
