Unusually warm weather persists throughout the forecast period with a blocking subtropical high pressure ridge to the south with a blocking high in the Great Australian Bight throughout the forecast period.

The persistent high blocking high results in roughly the same temperatures everyday!

Also possible smoke haze in the next few days depending on prescribed burns.

Also moist low level air will be advecting from the southeast lead to low level clouds forming to the east of the Darling Scarp having advected westwards  leading to a katabatic "waterfall" effect thismorning.
