Summary:
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 3 June to 7 June, 8 June to 12 June, and 14 June to 18 June. Rain events originating in the tropics and moving south are possible about 27 May to 31 May, 9 June to 13 June, and 20 June to 24 June.
Over Western Australia the strongest cold fronts should occur about 3 June to 7 June, 14 June to 18 June, and 21 June to 25 June.

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.
