Important rainfall was forecast to dampen drought-affected western Queensland, with the remote outback town of Boulia recording more than 50 millimetres by Tuesday morning.
Ms Westcott said although it will bring sub-30 degree temperatures to the south-east, the cooler Brisbane temperatures this week will feel warmer because of the increased humidity of ex-TC Trevor.
In addition, the very worst of summer was probably not yet over, though the very hot days will be few and far between, according to Ms Westcott.

Farmers have battled against the extended high temperatures and some crops have failed, meaning a knock-on effect in the supermarket. Single heads of cauliflower have sold for as much as $9.
Bree Grina from Bundaberg Fruit and Vegetable Growers said farmers have had to work hard to adapt, even applying sunscreen to their crops.
"It’s a spray-on powder, which obviously washes off long before the crop goes to market," she said.
However, for some, the hot weather has simply become part and parcel of living in Queensland.
Perina O’Connell, who lives in Mundubbera in the Wide-Bay Burnett said: "What heatwave? It’s Queensland, the weather is always the same, the weatherman can never get it right. This weather is the best, why do you think southerners come up from the cold?"

Heidi Newnham, who resides in Gayndah in the North Burnett said: "Other locals are saying this is extremely unusual weather for this time of year ... I'm originally from the UK so any Aussie weather is too hot for me!"
Cairns-based snake catcher Matt Hagan said the recent heat had resulted in fewer snakes coming out during the day, with the reptiles choosing to emerge during the cooler nighttime.
"When it’s really hot up here, like 40 degrees, we get very little work, except at night time," he said.
"Those really warm nights increases the snake activity a lot. And the big wet season we’ve had up here is the other major factor that brings the snakes out.
"Further south in Brisbane, where it’s been a particularly hot and dry summer, the reptiles have been kept at bay."
It's not just snakes who have been feeling the heat.
In November, north Queensland wildlife carers reported that about 23,000 spectacled flying foxes had died – an estimated one-third of the total population – after temperatures rose above 42 degrees.
On Tuesday, bat conservationist Keith Falkiner said the past summer had been devastating, with record temperatures leading to the demise of flying foxes en masse from Victoria to Queensland.
"Forty-two degrees really is the number where they simply can’t survive," he said.
And while he’s "not optimistic at all" for the future of the species due to wider human interference, he was hopeful these deadly temperatures were "just an aberration".
