Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 24 December to 28 December, 28 December to 1 January, and 5 January to 9 January. Rain events originating in the tropics and moving south are possible about 10 December to 14 December, 16 December to 20 December, and 28 December to 1 January.
Over Western Australia the strongest cold fronts should occur about 16 December to 20 December, 24 December to 28 December, and 28 December to 1 January.

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.
