A ridge extends across the southwest coast. An inland trough and low will move westwards on the weekend across southern and central WA, moving close to the west coast on Sunday. A high will develop south of the Bight on the weekend and move east for the following few days. On Monday the low will slip into the Bight and the trough will move east, ahead of the next cold front which will approach on Tuesday.
