At the start of the week, a cloudband with embedded thunderstorms stretched from northern Queensland to eastern Victoria, east of a surface trough which extended from north-western and central Queensland, through inland New South Wales to East Gippsland in Victoria. A broad trough also extended across northern and western Australia Thunderstorms developed in central and northern Western Australia, and across large parts of the Northern Territory.
Thunderstorms and showers with moderate falls were again recorded across northern Australia extending from the Kimberley, the north and central Northern Territory and into north-eastern Queensland.
