Queenslanders as far north as Rockhampton are digging through wardrobes for winter woolies as a cold snap hits the state.
Temperatures across the southern half of the state are expected to drop up to six degrees below the July average as a wave of cold air pushes through from the south.
The drop in temperatures has already hit with Roma, west of Brisbane, dropping to minus 1.7 degrees Celsius on Friday morning.
Parts of the Granite Belt including Oakey and Stanthorpe were also below zero on Friday morning.
Those regions are expected to get even colder on Saturday and Sunday morning with overnight minimums forecast to drop to as low as minus 6C in some areas.
Brisbane temperatures are forecast to drop well into single digits over the weekend with forecast lows of 6C on Saturday and Sunday.
Bureau of Meteorology forecaster Chris Joseph said the cold air is expected to penetrate much of the southern half of the state and possibly up into the lower regions of the Gulf.
"We're sort of drawing a line of anywhere south of Boulia to Rockhampton, anywhere south of that latitude is the area in the frost-prone zone I guess you'd call it," Mr Joseph told AAP.
Despite the chilly mornings, Mr Joseph said daytime temperatures are expected to be relatively stable with Brisbane and other south-east regions forecast to reach the early 20s.
The bureau expects cold temperatures to persist until early next week when overnight lows will increase back towards July averages.
