More storms predicted for SE Queensland

Southeast Queensland will have a third straight day of storms on Thursday, with an early-morning showing of thunder-and-lightning again a possibility.

Relatively rare early morning storms rolled over the state's southeast on Tuesday and Wednesday, leaving thousands without power and many others bleary-eyed due to a broken sleep.

BoM forecaster Andrew Bufalino said locals should prepare for the possibility of another early-morning wake-up call on Thursday.

"Most people got a nice awakening around 2-4 o'clock this morning (Wednesday) and there is a potential for more activity like that north of the Gold Coast," he told AAP.

"We've got an upper trough moving over the area in combination with a coastal trough, and in combination with that we have some very moist and unstable weather conditions, and that's driving a lot of shower and thunderstorm activity across the region."

The stormy weather is expected to ease by Friday, with more volatile conditions moving north of the Sunshine Coast.
