Up to 35mm is possible for parts on Friday, but rain is expected to clear on Saturday and Sunday ahead of the NRL grand final in Brisbane.

The best chance of thunderstorm activity in the south-east will be late on Thursday evening and Friday, but there is also the possibility of a storm pushing in from the west tomorrow evening.

Meteorologist Kimba Wong said thunderstorms could bring heavy rain, damaging wind and hail.

Redlands is predicted to get up to 30mm on Friday, while Logan and Beaudesert could get 25mm.

Lighter falls up to about 15mm are possible for Thursday.

Ms Wong said clear skies and a top of 29 degrees were forecast for the NRL grand final in Brisbane on Sunday.

"The weather is looking a little more favourable for the grand final this weekend," she said.

"Thankfully this (weather) activity is expected to clear off the south-east coast overnight Friday or early on Saturday and the weekend is expected to be much better."

Ms Wong said a trough and upper trough were combining to trigger broad areas of showers and thunderstorms.

"Thursday is looking like a pretty overcast day with a little bit of rainfall in the forecast during the day and possibly some storms pushing through right to the south-east coast late in the day," Ms Wong said.

"At this stage it looks like the focus for severe storm activity is probably going to be a little further inland than the metro areas on Thursday.

"You couldn't completely rule out some of that activity rolling through late in the evening, and then it looks like Friday is going to be the main day for us with any thunderstorm potential."

"With thunderstorms tomorrow, if they do become severe, it will most likely be during the afternoon and evening period," Ms Wong said.

"The risks with any severe thunderstorms if they do occur, is damaging wind gusts, heavy rainfall that may lead to flash flooding and hail is an added risk for tomorrow."

There was a slight risk of giant hail in parts if thunderstorms developed on Wednesday.

"This risk (of thunderstorms) will start to shift into the central and south-east inland parts of the state for Thursday, and then potentially spread to the south-east coast ... for Friday," Ms Wong said.

"There is a really active period of weather this week and probably the first significant severe thunderstorm outbreak across the state for this season, with the thunderstorm season officially kicking off on October 1."
