A west coast trough will move to the Goldfields and inland Gascoyne on Saturday as a weak front brushes past the south coast. A ridge will then develop across much of southern WA on Sunday, pushing the trough further north. Another weak front will brush the south coast on Monday, followed by the west coast trough returning by Tuesday.
