Weather Situation
A low pressure trough over eastern districts will continue to develop, forming a low pressure system to the north of the state by Thursday. This low will remain over southern NSW until it moves northward on the weekend, reducing its influence over Victoria. A high pressure system will also drift south of Tasmania over the coming days and will extend a ridge across the state on the weekend once the low shifts northwards.
