Much of southern Queensland experienced its coldest night in several years as temperatures plumetted five to 10 degrees below average. The coldest area was inland, where frost was severe. In the Maranoa, Roma dipped to minus five degrees, their coldest night in 14 years. It also chilled to minus five in Warwick, Stanthorpe, Dalby and Mitchell. Nearer the coast, on the Sunshine Coast and in Brisbane, there was some light frost. Maroochydore had its coldest morning in four years, dipping to just one degree. It got down to three degrees at Brisbane airport, its coldest in two years. Clear skies and dry winds, which eased enough overnight to allow it to get so cold, will persist until at least mid-week. That means the next few nights will be similarly cold. From Wednesday wind will turn from dry southwesterly to a more humid southeasterly, combining with cloud to bring warmer nights. By next weekend nights will be as much as five degrees above average, as warm as the start of the month. The southeasterly winds will also help bring showers late in the week with the aid of some cloud coming across from Western Australia.
