Furneaux Islands 28-day Rainfall Forecast
|Chance of rainfall within district|
25% to 50%
50% to 75%
The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are six main troughs. Currently the most significant troughs are near the longitudes of South Africa, the southwest Indian Ocean, Western Australia, the south Pacific, the southeast Pacific, and the Atlantic Ocean.
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 29 October to 2 November, 17 November to 21 November, and 24 November to 28 November. Rain events originating in the tropics and moving south are possible about 1 November to 5 November, 21 November to 25 November, and 26 November to 30 November.
Over Western Australia the strongest cold fronts should occur about 30 October to 3 November, 18 November to 22 November, and 25 November to 29 November.
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.
It will be a thundery end to the week in New South Wales, with storms possible each day from now until Sunday.
It will be a warm Wednesday for those living along the eastern seaboard as the spring temperature see-saw takes a swing.
