Nth Goldfields 28-day Rainfall Forecast
|Chance of rainfall within district|
25% to 50%
50% to 75%
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 South Africa, the Indian Ocean, eastern Australia, New Zealand, the south Pacific, and the southeast Pacific.
Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 29 June to 3 July, 3 July to 7 July, and 20 July to 24 July. Rain events originating in the tropics and moving south are possible about 5 July to 9 July, 10 July to 14 July, and 22 July to 26 July.
Over Western Australia the strongest cold fronts should occur about 29 June to 3 July, 4 July to 8 July, and 9 July to 13 July.
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.
The Bureau of Meteorology (BoM) says icy and windy weather affecting parts of the New South Wales central-west and the Blue Mountains will be easing today and has issued a strong wind warning for parts of Victoria.
Parts of New South Wales, Victoria and Tasmania were blanketed in snow, as a cold snap moved across the south-east coast.
Victoria is in the grip of a cold snap, with snow falling across the state and Melbourne bracing for a wintry weekend.
