The hemispheric long wave pattern has remained stable in recent weeks. There are six main troughs. Currently the most significant troughs are near the longitudes of the southwest Indian Ocean, Western Australia, eastern Australia, New Zealand, the south Pacific, and South America.
Summary:
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 26 October to 30 October, 2 November to 6 November, and 15 November to 19 November. Rain events originating in the tropics and moving south are possible about 6 November to 10 November, 10 November to 14 November, and 17 November to 21 November.
Over Western Australia the strongest cold fronts should occur about 27 October to 31 October, 2 November to 6 November, and 16 November to 20 November.

Forecast Explanation

This forecast is produced by a multi-model ensemble consisting of dynamical atmospheric models, which are forced by the latest observed atmosphere, ocean, land and ice conditions. The models are designed to simulate features of the real atmosphere, including the daily movement of long and short wave patterns in the Southern Hemisphere.

The future probability of rain in each district is estimated using output from the multi-model ensemble, combined with historical information about the difference between the model forecasts and observed rainfall.

In this deterministic framework the skill of the forecast tends to decrease with time, however the forecasts are updated daily to provide the latest estimates of rainfall probability out to 28 days.
