- Weather Situation
- A high pressure system well to the west extends a weak ridge across northern Victoria. A cold front crosses southern parts of Victoria Tuesday as the high moves over the Bight. The high then moves southeastward, drifting into the Tasman Sea by Thursday where it will continue to extend a weak ridge over Victoria. A cold front moving through the Bight will reach western Victoria later Friday, crossing the State on the weekend.
