Weather Situation
A trough has moved through the state's south this morning, and this system is followed by a ridge developing in its wake. Fresh northeasterly winds will develop later Tuesday as the ridge extends to the Tasman Sea and a high pressure system forms within it. Then, the next trough brushing the southern and central parts of the coast midweek will bring another south to southeasterly wind change in its wake, before stalling about Hunter or Mid North Coast later in the week.
