As a result, we’re looking at small NE windswells for temperate NSW, with workable trade swells for the sub-tropics and a marginal amount of that swell filtering down to temperate regions.

A large but not especially strong (1029 hPa) high pressure cell is west of Tasmania and slowly moving E where it enters the Tasman and becomes very slow moving. That will be the dominant feature of our synoptic set-up for some time, with a classic summer wind signal of SE winds in the sub-tropics, tending NE through temperate NSW.

We’ll see the NE flow ramp up on Sun across the MNC, grading lighter the further north you go,  as an approaching front and cut-off low really tightens the pressure gradient.

Another unstable, troughy week ahead with humid, unstable air over the continent creating a series of troughs, one of which forms a slow moving trough of low pressure off the Mid North Coast which interacts with a weak high pressure cell drifting in the Tasman.
