Winter made itself known in Queensland this morning as some places endured their lowest temperature in two years. A cold pool of air combined with clear skies and light winds sent the mercury plummeting across much of the state last night. As the sun rose this morning, frost could be seen covering patches of ground from the southern border up to the Northern Goldfields. It was the coldest morning in two years and the coldest June morning in four to six years at Hughenden (2C), Longreach (2C), Richmond (2C), Townsville (9C) and Cairns Airport (13C). The lowest official temperature in the state this morning was -2.1C at Oakey and Wellcamp Airport, located in the frost-riddled Darling Downs and Granite Belt District. Tomorrow morning is going to be another chilly by most Queenslander's standards, with widespread frost developing inland and temperatures dropping to single digits near the coast.
