Brisbane is set for a warm spell with temperatures expected to reach 30 degrees this weekend. It will be the warmest weekend that Brisbane has seen since January of this year. Temperatures have remained mild and slightly below average for much of February and March so far. The warm spell will also bring a brief reprieve from the showers that Brisbane has experienced over the past two months. With the mercury set to reach into the low to mid thirties tomorrow, this will be a run of 3 days over 30 for Brisbane, although the heat is not set to last. A developing trough will bring some showers and a cooler change late on Sunday. Brisbane residents might have to wait another week for it to clear up again.
