Weather Situation
A cold front moving across the Bight will stall over central SA on Sunday as a low pressure system develops near Kangaroo Island. The low is expected to move north over the Eyre Peninsula early next week, weakening as it moves into NSW. A trough may linger near the southern coasts before weak ridge of high pressure begins to move across SA later in the week.
