- Weather Situation
- A cold front clears eastern Victoria early this morning leaving a cool westerly airstream in it's wake. Embedded cold fronts and troughs within the westerly airstream will cross southern Victoria at times during Sunday through until Tuesday. The westerly airstream weakens on Wednesday as a high pressure system over the Bight extends a ridge over Victoria.
