There may have been a bit of a lull in the weather of late, but that is coming to an end this week.
"We've got those two extremes this week, with unstable and stormy conditions across eastern Australia and really hot, dry conditions across western Australia," the Bureau of Meteorology's Sarah Scully said.
"That's combining with an upper level trough that at the moment is over south-eastern Australia, as well as a deepening surface trough."
All of that moisture and lift is the perfect breeding ground for storms.
"There's a potential for severe thunderstorms, heavy rainfall, damaging wind gusts and large hail," she said.
Today there is the potential for severe thunderstorms along the east coast and adjacent inland areas in New South Wales.
Ms Scully says an easterly burst is expect to push up the coast and could bring showers and storms to the Sydney area.
The severe thunderstorm threat pushes into the central and north-central parts of NSW, extending into Queensland.
Flash flooding, damaging winds and hail are all on the cards.
By the end of the week, showers and thunderstorms are expected to extend from tropical Queensland all the way down to NSW, through Victoria and into Tasmania.
Those on the south-east Queensland coast should pay particular attention to warnings on Thursday, when heavy rain and severe storms are expected.
Concentrated heavy falls
Ms Scully said it was difficult to predict what the rainfall totals would be, but said there was "a lot of moisture through the air".
"There is the potential for 50 millimetres to 100mm beneath thunderstorms," she said.
The larger totals are not expected to be widespread, however.
"You might have one community or one farm that receives those types of rainfall totals, but just down the road they may receive none," Ms Scully said.
If you are wondering when the tropical weather is going to end, you shouldn't hold your breath — summer might be over next week, but the tropical wet season lasts until the end of April.
No let-up in the west
Meanwhile, scorching conditions in the west are continuing.
"We've got a lot of really hot, dry, windy conditions over WA which are elevating fire dangers there," Ms Scully said.
"Also with some severe to extreme heatwave conditions developing in parts of WA."
Maximum temperatures across much of the interior parts of WA are five to 10 degrees above the February average.
Ms Scully said the "really, really warm conditions" were likely to stick around for a while yet.
"There's no really significant rainfall forecast for WA at all," Ms Scully said.
