Brisbane has had a colder than average week, but a run of hot days are just around the corner.
Since last Friday Brisbane's maximum temperature has been at least two degrees below average, sitting around 23. This was thanks to cloud cover as a result of moist southeasterly winds and low pressure troughs.
From tomorrow a trough developing over the state's west will cause winds to tend more northerly. These northerlies will draw down heat from the nation's interior, pushing temperatures close to the 30 degree mark. On Friday winds are likely to tend northwesterly and become gusty, leading to a particularly hot day. At this stage, a top of 34 degrees is the forecast for Friday. If it gets this hot it will be Brisbane's warmest day since early February and their hottest September day since 2009.
The trough will cross the state on Friday, possibly bringing showers and storms for Brisbane in the afternoon or evening. This will lead to a cooler day on Saturday, followed by a return to temperatures in the mid twenties by early next week.
