An icy blast from the Antarctic is about to sweep southern Queensland, bringing chilly temperatures, frosty winds and even snow.
Temperatures in Brisbane are set to dip up to five degrees below the July average and snow flakes are expected to fall at Eukey near the NSW border.
The effects of the icy blast will be felt from Sunday and temperatures are expected to remain chilly until Friday.
Bureau of Meteorology senior forecaster Brett Harrison said snow was expected to fall on upper parts of the Granite Belt, most likely at Eukey.
"There's a pretty good chance of seeing snow, particularly on Sunday morning," he told AAP.
Brisbane is set to shiver through its coldest day of the year on Monday, with a maximum of 15C and minimum of 6C forecast.
The maximum is five degrees below the July average, and the windy conditions will make temperatures feel even colder, Mr Harrison said.
He said the icy blast was due to cold air coming all the way up from the Southern Ocean.
"We've got a low pressure system that's going to develop around Victoria and it's going to push all of that cold air throughout the interior of NSW and into Queensland," he said.
Before the cold snap hits, thunderstorms are expected to hit parts of southern Queensland.
Storms are forecast for the Darling Downs on Friday and could extend into Brisbane on Saturday.
