Residents of southeast Queensland will be reaching for jumpers and umbrellas tomorrow, with many places likely to see their coldest day in at least a year. Thick cloud and an associated band of rain will prevent any sun from reaching the ground throughout the day, with temperatures only set to reach the mid-teens. This cloud has already brought some cold days across Central Australia. Yesterday, Uluru reached just 11 degrees, while Ernabella struggled to 9 degrees. Today, Charleville had reached just 13 dgerees by 2:30pm. Brisbane is expected to reach a top of just 17 degrees tomorrow, its coldest day in a year, although there is potential that the city will get even colder. Similar temepratures are also expected across the rest of the southeast, with maximums five or six degrees below average for this time of year. The cold will reap some rewards for farmers though, with widespread falls of 10-20mm likely across the region including the Granite Belt, with potential for up to 40mm. The rain and cloud will clear early on Saturday to give way to a generally sunny and dry weekend, with temperatures returning closer to average. Similar conditions will persist until at least mid next week, although the clearer skies will mean a return to the cold mornings, similar to earlier this week.
