It's been a hot day for parts of southeast Queensland, but a cooler change is sweeping through the region. Built up heat from over central Australia was dragged over the region by northwesterly winds during the morning, bringing the hottest November day for many years to a range of places. Maryborough was one of the warmest, maxing out at 36 degrees, its warmest November day in 18 years. Double Island Point reached 33 degrees at midday, which was the hottest day there since January and the hottest November day since 1957. Meanwhile Bundaberg airport recorded their hottest day since February at 32. For parts of the Sunshine Coast it was the warmest November day in three years, including Tewantin where it reached 33 degrees and the airport where it hit 31. A cool southerly change pushing up the coast arrived at the Sunshine Coast at around lunch time causing temperatures to plummet. Double Island Point cooled by nine degrees in less than an hour as southerly winds with gusts of up to 80km/h swept away the heat. The southerly change arrived at Maryborough at 1:30pm local time, bringing an end to the intense heating there. The days will be cooler over the weekend with temperatures expected to be closer to average. A high pressure system will direct humid southeasterly winds into the region, bringing cloud and isolated light showers to coastal parts of southeast Queensland.
