Weather Situation
A high pressure system over the southern Tasman Sea is extending a ridge along the NSW coastline, while a trough is brushing the south, moving up the southern and central parts of the coast as a southerly change today through to early Wednesday. Then, another high pressure ridge is expected to drift across the state midweek, before a strong cold front moves across the coastal waters later in the week and into the weekend, with a fresh southerly wind change in its wake.
