A high pressure centre near the western south coast extends a ridge over southern parts of the state. The ridge will persist over the region for the remainder of the week as the high pressure centre slowly moves east. A cold front will then cross the local waters on Sunday, followed by another ridge which will develop over southern WA from Monday.
