Severe storms smashed south-east Queensland on Tuesday afternoon, tearing a roof off a house and leaving about 19,000 properties without power a day after the lights went out for thousands of others.

It comes as the Bureau of Meteorology expects south-east Queensland residents to swelter through hot nights for the rest of this week, with the humidity making it even more uncomfortable.

A high of 35 degrees was predicted for Brisbane on Wednesday before dropping closer to 30 degrees at the weekend. Minimum temperatures of about 25 degrees are expected to remain into next week.

Day-time maximums were tipped to hover about 30 degrees on the Gold and Sunshine coasts, with Ipswich and the Lockyer Valley edging as high as 37 degrees into Friday.
