Weather activity across south-east Queensland this week will be "one to watch" with a risk of severe thunderstorms, large hail and heavy rainfall.

It comes as heavy falls were recorded overnight, with Mount Glorious recording 75 millimetres, Beerburrum on the Sunshine Coast recording 48mm and Brisbane recording 35mm.

Gatton and Amberley also recorded 36 and 38mm respectively, which was the highest October rainfall in four years for those areas.

The Bureau of Meteorology (BOM) said wet weather, along with cooler temperatures, were set to continue across much of south-east Queensland over coming days.

Senior Meteorologist Felim Hanniffy said the area received between 20 to 40mm of rain on average with some isolated showers bringing larger numbers in some areas.

"Quite a decent bit of rainfall right across the south-east and even the Wivenhoe Dam picked up 40mm as well ? so that would be much needed for this particular area," he said.

"So [the week's weather activity is] one to watch ? quite an unsettled week and quite in keeping with the time of year given that now we're transitioning into the severe weather season."

He said the activity was being caused by a trough system, an upper feature and an associated cloud band.

"Over the south-east quite a depth of clouds moved across the area ?  so you had the main trough and the upper feature moving over the area overnight and during this morning and hence why we had all that rain overnight," he said.

Mr Hanniffy said the rain activity was set to ease today before another system brought rainfall and thunderstorm activity later in the week.

"The heaviest rain probably has passed ? there'll be still shower activity for the rest of the day but looks like the heaviest of the rainfall is now kind of slowly contracting off the south-east coast," he said.

"It's quite an unsettled next few days. We think the remains of a trough is going to remain inland to the south eastern interior, so still the potential for shower activity but then that shower activity picks up again for Thursday and Friday as another trough moves in from the west."
