Quintessential conditions are on the way to finish off the Brisbane Festival with the Riverfire set to light up the citys's skyline on Saturday. While a low pressure trough brushing the region will bring the chance of a shower or two during Saturday morning, cloud will decrease during the day to give way to generally clear skies from the afternoon and into the evening. It also isn't likely to be anywhere near as hot as it has been the last week. After a pleasant day with a top of 28 degrees, it will dip to a comfortable 22 or 23 degrees for much of the evening. The perfect weather will make for smooth-sailing throughout the evening, where more than 450,000 people are expected to attend and more than 6000 fireworks will be launched. The Riverfire starts at 7pm.
