Weather Situation
Vigorous southwesterly flow is easing as a cold front and low pressure system move east into the Tasman Sea. On Thursday the flow will continue to weaken as a high pressure system moves over Victoria. That high will remain slow-moving over the State through Friday and Saturday, when a weak cold front is forecast to approach from the southwest.
