A high pressure ridge over the east will begin to weaken as a cold enters the west of the SA early today. This front is expected to reach eastern districts later on Sunday with an associated low pressure system developing off the southern coasts. The low is expected to move across the southeast on Monday then eastwards into NSW by Tuesday with a trough lingering across the south of SA.
