Weather Situation
A trough over far eastern Victoria will move over the Tasman Sea this evening and a cold front will move across Tasmania and Bass Strait on Tuesday morning. A cool southwesterly airstream will follow as a high pressure system drifts eastwards across the Bight. By Thursday the high will be centred near Tasmania and will direct a warmer east to northeasterly flow over Victoria. The high will move over the Tasman Sea on Friday.
