Southeastern QLD has endured chilly mornings over the past few days, with some places seeing their coolest run of May mornings in 30 years. Yesterday morning Coolangatta cooled to 4.6 degrees, 9.5 below the May average. This was its coldest May morning in nine years and its coldest morning since September last year. It reached 5.9 degrees this morning making it the longest run of days below 7.5 degrees in May since 1983. Before this run of cool days, Coolangatta hadn't dropped below ten degrees this year and since then it's had their coldest run of mornings since August last year. The Gold Coast Seaway also had a cool morning, recording 11.4 degrees, its coldest morning since October last year. Further north, Maroochydore dropped to 5.1 degrees this morning making it the third day in a row below 7 degrees and its coldest morning since August last year. This run of three cold mornings is its coldest run of days below 7 degrees in May since 2002. Amberley and Brisbane experienced their coldest morning since September last year recording 1.6 and 8.3 degrees respectively. This makes it Brisbane's coldest May run of three days below 9 degrees since 2001. It is likely to be quite cool tomorrow morning again as skies remain mostly clear before a low and trough move over the region on Wednesday, increasing minimum temperatures. The low and trough are likely to bring rain on Wednesday and Thursday before clearing on Friday.
