Hot weather to return to 5C above average with 10 to 20 per cent chance of a storm HOT weather returns briefly to Brisbane tomorrow, with the city forecast to get 34C - 5C above average - and a 10 per cent to 20 per cent chance of a storm and showers. A north wind will bring the warm conditions, pushing away a dry and cooler air mass that has seen overnight temperatures in the city drop 4C to 5C below average. Weather Bureau forecaster Rick Threlfall said storms and showers were more likely on the Darling Downs tomorrow although it was possible the remnants of one or two might get through to Brisbane. "The cooler conditions are down to a southerly change that came through on the weekend," he said. It brought drier air and this always lets temperatures cool down more easily. The city was down to 16C overnight, Archerfield 14C and Ipswich 13C. Cooler conditions will again return on the weekend. Birdsville in the far southwest had 12mm of rain overnight, more precipitation than it has had in the entire past six months. Severe fire conditions continue in the Channel Country and Maranoa and Warrego districts with the odd storm in the Gulf of Carpentaria. The monsoon trough has weakened over the north.
