Weather Situation
A high pressure ridge weakens over the east as a cold front approaches western Victoria. This front will cross the State through Saturday, clearing the far east by early Sunday morning, before a high pressure system develops over the state in its wake. This high will drift eastwards into the Tasman on Monday as a low pressure system develops in the Bight, extending a weak trough off the western coast on Tuesday.
