Hot dry winds from Queensland's interior are expected to raise temperatures by about 9C above average in the state's south east this week.
Brisbane city is expected to see the mercury reach about 33C on Friday, while 50km further inland at Ipswich temperatures could hit 36C for the first week of spring.
The dry winds could see fire weather warnings issued for parts of south east Queensland, says Bureau of Meteorology forecaster Harry Clark.
Mr Clark says a low pressure trough over western Queensland was expected to be responsible for the winds.
Towards the end of the week temperatures are expected to reach 34C in Rockhampton and 27C in Mackay.
