Bureau of Meteorology, May 20, 2020

A cold front produced moderate falls in western Tasmania, while onshore flow brought showers and moderate falls to the east coast of Queensland and New South Wales.

Past seven days: At the start of the week, a cold front tracked across southeast Australia, interacting with a trough extending through New South Wales and inland Queensland. Moderate falls resulted in western Tasmania, while widespread light falls were recorded over much of Victoria and southeastern South Australia. Localised moderate falls were observed on the New South Wales south coast.

In the middle of the week, a surface trough situated near the east coast triggered showers and produced moderate falls in parts of coastal New South Wales and in southeastern Queensland. A trough across inland Queensland also produced scattered showers in parts of inland Queensland.

Moist onshore flow produced showers and moderate falls along the north tropical coast of Queensland in the first half of the week, as well as in Arnhem Land in the Northern Territory. A moist onshore flow continued to bring showers to parts of the east coast of Queensland and New South Wales for the rest of the week.

At the end of the week, a cold front brushed southwest Western Australia, and produced light falls along the south coast of Western Australia.
