Weather Situation
A low near Tasmania extends a trough over southeastern VIC on Tuesday. The low moves eastwards into Wednesday allowing a high pressure system to the north to extend a ridge over the west, moving slowly eastwards across the state through to the end of the week as the high moves out over the Tasman Sea on Saturday. A weak front clips the south on Thursday.
