All forecast models are agreeable on a building high pressure ridge which delivers a hot mid-October to Australia. On the northern fringe of the ridge, monsoon rain affects northwest/north continent. However, East/Southeast Australia is very dry.

The latest North Atlantic oscillation (NAO) 15-day forecast reveals an evolving moderate-to-strong negative phase usually causal to a blocking high pressure over Greenland and a compensating upper trough into the Northeast U.S. Forecast models have resisted that forecast solution over the weekend, however, at 12Z today, the GFS follows the -NAO guide.
