A ridge of high pressure will move eastwards over the State through to the weekend as a trough deepens over western then central parts of the country. This trough will cross the State on Saturday and combine with a cold front that clips southern Tasmania. The ridge will build briefly over Victoria on Sunday before a series of troughs extend over the State during the beginning of next week.
