T-shirts to thermals: Qld’s balmy winter ‘anomaly’ set to end with cold blast

Southeast Queensland is set for a jolting weather flip, swinging from unseasonal warm temperatures to an icy plunge in the space of a day.

Southeast Queensland is set for a jolting weather flip, swinging from unseasonal warm temperatures to an icy plunge, according to the Bureau of Meteorology.

Bureau meteorologist Shane Kennedy said the southeast had felt a weather anomaly with unseasonable winter warmth this past week.

Brisbane recorded an unusually balmy 25C on Tuesday, with the mercury expected to hit similar levels on Wednesday.

“Maximum temperatures across the southeast were generally in that two to five degrees above average range in southeast Queensland yesterday afternoon,” Mr Kennedy said.

“We’re looking at about four to five degrees above average today.”

According to the Bureau, the higher temperatures are being caused by a trough system pushing north-westerly winds into the region.

But the forecaster said the warmer weather would be short-lived, with temperatures expected to plummet significantly by Thursday with a chance of frost in inland areas.

“Overnight temperatures, they’re definitely dropping below average from tomorrow,” Mr Kennedy said.

“So minimum temperatures will likely go back into single figures for the city, dropping down to around the eight or nine degree mark the next couple of days and likely to get close to zero in the west. And then we’ll likely see some frost inland as well”

Mr Kennedy said maximum temperatures will also drop to slightly below average for the region.

“Those afternoon temperatures will be dropping down to around that 22C mark over the next couple of days, returning to average and then getting slightly cooler - close to average or a degree or two below the next couple of days,” he said.

But despite fluctuating temperatures, residents of southeast Queensland could expect a week filled with sunshine due to the trough system moving offshore.

“We’re expecting sunny conditions for basically the rest of the week, over the weekend and into early next week,” BOM senior metrologist Brooke Pagel said.

“With this trough system, we’re not expecting any rain out of it. There may have been a sprinkle of a shower around the Gold Coast area, only amounting to one or two millimetres.”
