SA hit by string of sweltering days

A string of steamy hot days has kicked off in South Australia, with big chunks of the state to simmer through heatwave conditions for at least a week.

The Bureau of Meteorology expects the mercury to hit a top of 36C in Adelaide on Thursday, backed up by highs of 39C on Friday and Saturday.

Temperatures will drop in the city late on Saturday, leading to milder tops on Sunday (30C), Monday (31C) and Tuesday (31C).

But other parts of the state are unlikely to get the same relief, particularly the northeast, where temperatures in towns like Leigh Creek and Moomba are expected to climb above 40C on Saturday, Sunday and Monday.

This is because a trough set to move away from Adelaide on Saturday is likely to stop up north and stick around for a while, the weather bureau says.

"It's just going to hang around the northeast of the state and become near stationary. So places in the far north of SA are probably going to be in a heatwave for even longer," BOM senior forecaster Tina Donaldson said.

The area could also experience thunderstorms on Thursday but Ms Donaldson said heat will be the defining weather feature over the coming days.

The SA Country Fire Service is reminding people to have a bushfire survival plan ready that considers the circumstances of school holidays.

"It's important to think about what you would do now that children are home on school holidays, or if you're travelling to a different part of the state for a break," a spokeswoman said.
