Brisbane weather: expect rain Brisbane can expect a lot of rain going into the weekend. Brisbane backyards are set to receive a welcome drenching over the next two days with rainy days set to be the norm into next week. The Bureau of Meteorology is predicting falls of 30 to 40 millimetres on Wednesday and Thursday, with senior forecaster Jonty Hall saying the city could easily see falls in the 50-100 millimetre range for the week. He said the "unsettled" weather was likely to continue past Thursday. Weatherzone: Brisbane storm tracker "It doesn't look like it's going to end any time soon," he said. The rainfall follows an extended dry period. Only about 200 millimetres of rain has fallen in the city over the past six months. "August, September and October are our driest part of the year, and we start to see thunderstorm activity increasing through November-December," he said. The thunderstorms are fueled by a large, slow moving trough in the south-west, as well as northerly winds which is bringing in moisture off the Coral Sea. "There's a trough that runs through the central parts of the state from the Gulf of Carpentaria down to the Darling Downs area," he said. Anywhere west of that is still very dry, with no thunderstorms expected out through there. Rainfall is expected as far north as Rockhampton. A thunderstorm shook Stanthorpe last night, ripping off a 80x40-metre hotel roof. A Department of Community Safety spokesperson said 22 State Emergency Services volunteers responded to the incident, with 26 units receiving water damage.
