Forecast issued at 4:15 pm EST on Friday 28 August 2015.
A low pressure complex is situated over the western Tasman Sea, while a large high pressure lies over the Southern Ocean west of Tasmania. During Saturday a front associated with the low complex will cross Victoria. At the same time the high will move well south of Tasmania, with a ridge extending from the high into central Australia. Both the low complex and ridge will move slowly eastward, the latter reaching western Victoria late on Sunday then the eastern half of the State by late Monday. The next trough of low pressure is expected to enter western Victoria during Tuesday, as the ridge weakens.
