Cool, wet and windy conditions are expected over south-east Australia for the end of the week and over the weekend.

The first front is crossing Victoria, New South Wales, and Tasmania today, bringing a band of rain and thunderstorms that is forecast to intensify over the western slopes of the Great Dividing Range this afternoon.
Severe thunderstorms may develop over NSW and southern Qld today, and may produce damaging winds, large hail, and/or heavy rainfall.
Today’s front and rain will gradually move away into the Tasman Sea tomorrow, but the reprieve will be short-lived over parts of the south-east, as a follow-up front, bringing gusty showers and thunderstorms to southern South Australia today will move across Victoria, Tasmania, and southern NSW tomorrow.
Cold and showery weather will continue over Vic, Tas, southern NSW, and south-east SA on Saturday and Sunday.
Maximum temperatures are expected to be 4-8°C below average over the weekend, and the snow level will drop to around 1100-1200 metres.
Rainfall over coming days is expected to cause renewed river rises, especially over parts of NSW, northeast Victoria, and northeast Tasmania, and Flood watches have been issued. There are numerous flood warnings current for inland NSW, southern Qld, and northern Victoria
Severe thunderstorms are a risk today, especially over inland parts of NSW and southern Qld. Warnings may be issued for severe storms producing damaging winds, large hail and/or heavy rainfall that could lead to flash flooding.
Windy conditions are also forecast to develop but are currently expected to stay below warning thresholds. The Bureau will continually monitor conditions and warnings will be issued if necessary.
Note that saturated ground may result in damage from winds even below warning thresholds.
