With less than 10 days left until the end of winter, those living in southern Queensland were reminded this morning that the chilly season is not over just yet. Temperatures plummeted as a cold air mass in the wake of a front combined with clear skies and light winds during the night. This combination is the perfect set up for those chilly winter mornings, when extra blankets and flannelette PJ's are in high demand. Bundaberg dropped eight degrees below average to an overnight low of 3.3 degrees, the coldest temperature recorded there for 17 years. In the state's capital it reached 6.8 degrees just after 4am, making it the city's fourth coldest morning this winter. Temperatures were up to 8-9 degrees below average for many locations from Yeppoon to the NSW border and inland to parts of the Maranoa. Oakey Airport reached minus five degrees for the second morning in a row, which has not occurred since 1992. The high pressure ridge responsible for last night's nippy conditions will weaken slightly today as a front moves through NSW. Friday morning will be another cold one, although temperatures should fall to a couple of degrees above this morning's values thanks to a slightly milder air mass and moderate westerly winds. Despite not being as cold as this morning, tomorrow's minimums will still be 3-6 degrees below average across much of southern Queensland. So don't go putting those extra blankets away just yet.
