A high pressure ridge extending from the southeast will begin to weaken as a trough approaches from the west, crossing the state on Tuesday. A weak high pressure ridge will follow the trough on Wednesday, developing across the south and persisting while a trough sits just north of the border. This trough will begin to move into state on Friday, pushing into Gippsland and eroding the ridge.
