- A high pressure system is extending a ridge over the northern waters while a cold front and its associated trough approach from south. A southerly change is forecast for Friday as the front moves north along the coast reaching the northern border early Saturday morning. In the wake of this, the high pressure moves east, reaching the southern Tasman Sea by Sunday and bringing settled weather. This system is then expected to become slow-moving for several days.
