Issue Notes

The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are four main troughs. Currently the most significant troughs are near the longitudes of South Africa, Western Australia, the southeast Pacific, and South America.
Summary:
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 30 April to 4 May, 7 May to 11 May, and 13 May to 17 May. Rain events originating in the tropics and moving south are possible about 17 May to 21 May, and 28 May to 1 June.
Over Western Australia the strongest cold fronts should occur about 30 April to 4 May, 7 May to 11 May, and 13 May to 17 May.

Issued Apr 25

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.
