Weather Situation
A high over the Tasman Sea extends a ridge over northern coastal waters, while a trough brushes Sydney Waters this afternoon and continues heading north, bringing a coastal southerly change in its wake, before stalling about the Hunter Coast midweek. Then, a series of high pressure systems will pass to the south, maintaining moist onshore easterly winds through the second half of the week.
