A tropical low pressure system near the NT boarder extends a trough over central and southeastern SA. The low will move southwards on Sunday, before a cold front moves through the Bight on Monday, pushing the low out to the east of SA late. A high pressure system will then move into the Bight, extending a ridge over the state on Tuesday and Wednesday.
