- A weak cold front over the south coast will quickly clear eastward into the Bight tonight. A weak ridge currently over central parts of the State will settle southward on Thursday and Friday before moving into southeast Australia during the weekend. A trough will deepen down the west coast from late Friday, moving inland later on Saturday ahead of another weak cold front which is slated to reach the lower west coast on Sunday. As the trough moves inland a new ridge will begin to strengthen across the west coast.
