Weather Situation

A deep low pressure system over South Australia will continue east tonight while filling, as a high becomes established over the Tasman Sea just east of Victoria, combining to direct a warm and humid northeasterly airstream establishes over the state. The low will continue to dissipate tomorrow, however an associated trough is expected to enter the west of the state later in the day, before crossing the rest of Victoria early on Sunday, as a low pressure complex develops south of the Bight. An associated cold front will approach western Victoria late Sunday, before crossing the state during Monday. The low pressure complex will then approach Tasmania during Tuesday, as another in a series of cold fronts crosses Victoria.
