Parts of southeastern Queensland have received the most significant August rainfall since 2011.
A pair of low pressure troughs have been interacting with each other in the past couple of days to steer a very moist and unstable onshore flow over the QLD coast between the Capricornia Coast and the Gold Coast.
One of these troughs is lingering, more or less stationary, over inland parts of the southeast. In addition to triggering some showers and thunderstorms over the Darling Downs and Granite Belt & Maranoa and Warrego districts last night, it has also been working in conjunction with a coastal trough to draw moisture from the ocean as far inland as Dalby.
Gayndah Airport picked up 14mm making it their heaviest August total since 2011, while further east Coops Corner, just north of Noosa picked up a huge 59mm.
Noosa Heads themselves also received an impressive 44mm, while further west the rain gradually became lighter as the moist winds dropped most of their moisture on, and east of the ranges.
Over the weekend and into next week, this coastal trough will slip south and is likely to develop into an east coast low presenting the risk of heavy showers along the New South Wales coast as seen in Rob Sharpe's article - http://www.weatherzone.com.au/news/flooding-rain-on-its-way-to-coastal-nsw/125481.
