Severe-to-extreme heatwave conditions are predicted to hit central and southern Queensland and northern New South Wales for three days from Friday, with temperatures forecast to crack 40 degrees Celsius in some parts.
Bureau of Meteorology (BOM) senior forecaster Michael Knepp said dry air coming from western Queensland would send temperatures soaring over the weekend.
"We are looking at a possible heatwave with temperatures especially in western [Brisbane] suburbs remaining in the high 30s possibly getting to 40-41 for an extended period of time for five or six days," he said.
Many towns south of the Queensland border and west of the Great Dividing Range will endure several days of temperatures above 40.
The BOM predicts a top temperature of 44 in Moree, Walgett, Brewarrina and Bourke on Saturday, and those towns are set to remains in the low 40s on Sunday and Monday.
