Weather Situation
A high pressure ridge south of the state will persist over the coming days with multiple weak high pressure centres moving to the south. A low pressure trough will move west of the state late on Tuesday. This trough will be pushed northwards along the WA border as new high pressure system develops south of the Bight on Wednesday. This high will remain relatively stationary to the south on Thursday as it extends a weak ridge over the state.
