The front is forecast to enter western Victoria on Sunday afternoon, reaching central districts during the evening before crossing eastern Victoria on Sunday night. A high pressure system south of the Bight will move quickly east on Monday, moving over western Bass Strait by Monday night as it extends a ridge over southern Victoria. The high will then move over the Tasman Sea on Tuesday.
