Queensland will once again shiver through a cold and frosty morning as a cold snap continues to grip the state's southern half.
Overnight temperatures are expected to remain well below July averages for the second night in a row after a chilly start to Saturday.
Forecasters are predicting areas such as the Granite Belt and Darling Downs will once again be up to five or six degrees Celsius below zero.
Wellcamp Airport, just west of Toowoomba, posted the lowest temperature of the day on Saturday with minus 6.4C at 6.42am.
Nearby Oakey recorded a low of minus 6.3C just before 7am.
The cold weather pushed well up into Queensland with the outback town of Blackall dropping to 1.2C while Lochington, near Emerald, was just 0.5C at 7.11am.
Even Rockhampton, up on the state's central coast, dropped to a low of 6.5C just before 7am.
Brisbane is once again expected to have temperatures around six degrees on Sunday morning with forecasters expecting conditions to remain below average until Tuesday or Wednesday.
"We're definitely not through the cold snap as yet, you couldn't say that," Bureau of Meteorology senior forecaster Jonti Hall told AAP.
"It'll gradually get a bit milder through the overnight period - particularly over most of eastern Queensland - from Tuesday, Wednesday, next week."
Daytime temperatures are once again expected to be stable around 20C throughout the southeast.
Brisbane and other southeast coastal areas will also be hit by king tides on Sunday evening.
A forecast peak of 2.74m was expected on Saturday night at 10.52pm in Brisbane with a slightly lower peak forecast for Sunday night at 2.68m.
Brisbane City Council is warning minor localised flooding could be experienced in bayside, riverside and low-lying nearby suburbs.
Council is warning residents in those areas to avoid parking their cars on the street during the high tides.
