Weather Situation
A cold front over Tasmania will clear to the east early Wednesday morning, leaving a westerly flow in its wake. Westerlies will persist for the remainder of the week, with another cold front embedded in the flow forecast to cross on Thursday. A stronger cold front and associated low pressure system are then expected to approach Tasmania from the west by late Friday with the front expected to cross on Saturday as the low moves south of the state.
