The weather bureau says there will be severe conditions across parts of Queensland today, especially in the state's interior, as well as the possibility of lightning that can trigger fires.
Senior forecaster Ben Annells says there is a severe fire danger in southern and western parts of the state's Channel Country, with temperatures likely to reach 36 degrees Celsius at Birdsville, Ballera and Thargomindah.
Mr Annells says there will be some few showers in the south-east and central coast region, but conditions elsewhere will be wilder.
"Through the remainder of the state we should see showers and storms once again stretching from the northern tropics and the north-west of the state, right down through the central and southern interior," he said.
"Some of those thunderstorms are likely to be severe with damaging winds and large hail a possibility and also with some of the slower moving thunderstorms heavy rainfall is possible as well."
Mr Annells says there is the risk of lightning that can also trigger fires.
"It's a little bit of a mixed story as far as thunderstorms are concerned because in one sense they can deliver the rain, but they can also increase the fire risk due to lightning," he said.
