South Australia is set to cop two days of extreme heat before temperatures cool on Saturday night.
Adelaide is predicted to reach a top of 33 degrees today, before the mercury soars to 40 on Friday and Saturday.
Temperatures are then predicted to drop back down when a cool change sweeps through the state on Saturday evening, with the maximum temperature a mild 24 on Sunday.
An extreme fire danger rating has been issued for Adelaide as well as the Mount Lofty Ranges on Friday, while many parts of the state have an extreme fire danger rating for both Friday and Saturday.
The predicted maximums are set to fall below the city’s record temperatures for November. The hottest November day in Adelaide was recorded during the 2009 Adelaide heatwave when the mercury reached 43 degrees.
