Forecast updated at 7:58 pm EDT on Friday 21 October 2016.
A strong cold front over eastern Victoria will move out over the Tasman Sea tonight then form a low pressure system to the east of Tasmania during Saturday, resulting in a cold, unstable south to southwesterly airflow over Victoria. This airflow will gradually moderate on Sunday as the low drifts further eastwards. The next high pressure system will be centred just to the west of Victoria by late Sunday then drift eastwards across the State on Monday. A cold front will approach the State on Tuesday and is likely to reach western areas at night then extend to eastern Victoria during Wednesday.
