- Weather Situation
- A high well to the west continues to direct a cool west to southwesterly flow across the state, persisting into Thursday before the flow is forecast to gradually ease and turn south to southeasterly on Friday as the high moves eastwards over Tasmania. As the high is expected to slip to the south of Tasmania by the weekend, the flow over Victoria will further shift easterly by Saturday. A low pressure trough over South Australia is forecast to approach western Victoria late Saturday and slowly moves over Victoria into Sunday.
