Weekly rainfall wrap + rain outlook, 11 Nov 2020

Bureau of Meteorology, 11/11/2020

Troughs and onshore flow produced thunderstorms across the central west and central coast of Queensland, while a cold front brought moderate falls to south-west Western Australia.

Past seven days: For the week to 10 November 2020, rainfall was recorded in the Kimberley, south-west and south-east of Western Australia; in the north-west of the Northern Territory; and across the central west and central coast of Queensland and in areas of the Cape York Peninsula. Rainfall was also recorded from the central to south-east coast and adjacent inland districts of New South Wales, parts of eastern Victoria, and western and far north-eastern Tasmania.

In the first part of the week, a cold front and pre-frontal trough crossed south-east Australia, generating moderate falls in far eastern Victoria and south-eastern New South Wales. The trough passed over New South Wales, and a low pressure system developed off the New South Wales coast, generating thunderstorms and moderate falls along the central coast of that state. Widespread light falls were reported across much of southern and eastern Victoria, western Tasmania, and through central New South Wales.

In the middle of the week, a trough extended from southern Western Australia to the Kimberley, and stretched east through inland parts of the Northern Territory. The system generated an active cloud band with thunderstorms, with light to moderate falls over eastern parts of the South West Land Division, and the Kimberley in Western Australia, and the north-west Top End. A cold front crossed Tasmania, producing mainly light falls in western Tasmania.

In the last part of the week, a surface trough extended from the Gulf Country to southern inland districts of Queensland. A firm ridge of high pressure extended along the Queensland coast, and the surface trough deepened over central Queensland. Thunderstorms and showers produced moderate to locally heavy falls along the central coast, and over central western Queensland. Thunderstorms also developed in the Kimberley and south-east Western Australia in the vicinity of a surface trough.

At the end of the week, a strong cold front tracked over south-west Western Australia, and an associated low pressure system brushed along the south coast, with a low- to mid-level cloud band producing moderate falls in the south-west of the state.

Rainfall totals in excess of 100 mm were reported in parts of the central west, and central coast of Queensland, including the highest weekly total of 229 mm at Mt Jukes.

Rainfall totals exceeding 50 mm were reported in parts of the central west, and central coast of Queensland, in south-west Western Australia, isolated spots in the Hunter and Illawarra districts in New South Wales, and an area in western Tasmania.

Rainfall totals between 10 mm and 50 mm were recorded in areas of the South West Land Division, far south-east and the Kimberley in Western Australia, the north-west Top End, parts of the Cape York Peninsula, and across the central west and central coast of Queensland. Similar totals were recorded from the central to south-east coast and adjacent inland districts of New South Wales, parts of eastern Victoria, and in western and the far north-east of Tasmania.
