Storms, wind and cooler change for southern states

Rain, gusty winds and thunderstorms will roll across South Australia to end the week, ending the recent run of warm, dry weather.

A low-pressure system is causing the change, sending a cold front and trough from west to east starting today.

Showers, thunderstorms and strong winds are forecast to sweep across South Australia as the front advances.

South Western Australia is expected to experience these conditions from today, followed by South Australia tomorrow.

Victoria, Tasmania, New South Wales and the Australian Capital Territory will experience wet weather this weekend.

Rain will spread across much of the South, although totals will vary. Temperatures may rise 10 to 20mm in some areas, with isolated falls above 40mm possible, especially where thunderstorms are developing.

Winds will increase ahead of the front, with strengthening northerly winds giving way to cooler westerly to southwesterly winds as it passes.

Damaging winds are possible in parts of South Australia and western Victoria on Saturday, extending to higher ground in eastern Victoria and south-eastern New South Wales on Sunday.

Temperatures are expected to drop by about 5 to 10 degrees across much of the South as the system moves through.

Adelaide is forecast to drop back to around 19 degrees on Sunday and Monday after hitting the high 20s earlier this week.

Meanwhile, Melbourne is expected to drop from around 26 degrees on Friday to 22 degrees on Sunday, while Hobart will drop from the mid-20s to around 19 degrees on Monday.

Canberra will also cool, with temperatures dropping from 20 degrees this weekend to around 17 degrees by Tuesday.
