Brisbane's going to be warm and cloudy for the last day of the Brisbane Festival, although there may be some drizzle for the fireworks display.
A low pressure trough is directing hot and gusty northerly winds into Brisbane, leading to a hot day. By midday it had already warmed up to 27 degrees, and it should reach 29 by mid afternoon. This will make it the third day this week that it has been this warm, so a hat and sunsblock will be necessary while staking out riverside viewing spots.
As the trough approaches this afternoon, cloud will thicken over the city, causing light rain to develop tonight. The heaviest rain shouldn't fall until after 8:30pm, after the fireworks display. There may be some drizzle around earlier though, enough to warrant bringing a rain coat but not enough to dampen spirits.
On Sunday winds will tend southwesterly in the wake of the trough, bringing a noticeably cooler day, with a top of 23 degrees. There should also be some rain about in the morning, providing ideal weather for a Sunday sleep in after Saturday night's festivities.
