It’s a sweltering end to the week in southern Australia – but by Saturday some places will be 25 degrees cooler.

The hot weather is being caused by a tropical northerly flow which is today spreading right down across Australia’s interior and exiting in the south over Adelaide, Melbourne and even down to Hobart.

Heatwave weather will continue inland this weekend but coastal areas in the south will have a much cooler Saturday.

Here’s the dramatic temperature drop coming in over the next 24 hours…

• Adelaide  –  Friday 43C,  Saturday 27C
• Melbourne  –  Friday 44C,  Saturday 19C
• Hobart  –  Friday 33C,  Saturday 17C
