Weather Situation
A high pressure system over NSW will persist into Saturday as a cold front crosses waters south of the Bight. 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.
