Parts of south-east Queensland are bracing for below freezing temperatures as a "quite unusual" cold front blasts the region.
The Bureau of Meteorology (BOM) is warning of colder than average June temperatures to sweep the southern corner from today.
Across the state, Roma, in Maranoa, had the frostiest start to the day, with 0.6 degrees Celsius recorded just before 7am.
On the Darling Downs and Granite Belt, Warwick recorded the lowest temperature with 1C just before dawn.
In Wide Bay and Burnett, Kingaroy plummeted to 1C and in the south-east, Amberley, west of Brisbane, had the coldest start to the morning, with the mercury dropping to 2C.
A slow-moving high pressure system over the region could bring inland frost and freezing temperatures.
"There is a quite prolonged cold snap coming up."
Temperatures are expected to be below freezing on Wednesday and Thursday night in Toowoomba and the Granite Belt, but snow is unlikely.
Single-digit temperatures could sweep right across the south-east for the rest of the week, with Laidley and Ipswich, west of Brisbane, dipping to 3 degrees Celsius on Thursday night.
'Very chilly' days
Mr Kennedy said the bureau is predicting temperatures to be up to 7 degrees below average for the start of winter in some regions like the Gold Coast.
Gold Coasters are bracing to shiver through single-digit temperatures, with the Scenic Rim and hinterland expected to bear the brunt of the cold front for the area.
"We're quite likely to see some temperatures around that 6 or 7 degree mark [on the Gold Coast] by the end of the week, and potentially as cool as 2 or 3 degrees around the hinterland," he said.
Brisbane city's current record low temperature for June is 5 degrees, but it is not expected to break that record.
'Prolonged' cold front
Mr Kennedy said central and southern Queensland will see fairly widespread areas of frost.
"There's the risk to see some frost inland extending around the Beaudesert area up around the Gold Coast hinterland as well, particularly on Thursday, but then particularly on Friday, Saturday," he said.
Queenslanders should be prepared for a chilly weekend as the cold front is expected to last at least until next week.
"It might not be until Tuesday or Wednesday [next week] when we finally see those temperatures going back up into the double figures," he said.
"It's likely to be very chilly indeed."
