The east coast is set to cop a drenching this weekend as a northwest cloudband moves across Australia.
The system has already left parts of WA soaked, dropping 36 millimetres on the east Pilbara in the 24 hours to 9am on Thursday.
As it tracks east, it’ll combine with an influx of tropical moisture that will leave Aussies ducking for cover.
“We have this cloudband and trough that's cutting through the interior and dragging quite a bit of tropical moisture down,” Andrew Schmidt, meteorologist at Weatherzone told Yahoo News Australia.
“So that will bring showers to the east over the next several days as well as possible storms with the days now heating up a little.”
Heavy showers on the way
Forecasters say the rain will hit from tomorrow in NSW, particularly in the Central West slopes and plains as well as the Southwest slopes and plains.
“So around Dubbo and Narrabri, in those particular areas there's probably a good chance of some heavy showers with around a possible 30 millimetres of falls in 24 hours,” Mr Schmidt said.
“We could also see some storms as this trough pushes through.”
Heading into Saturday, the showers will move a bit further east.
“Probably more so towards the Northern Tablelands as well as Southeast Queensland,” Mr Schmidt explained.
“So basically all the way extending up into Chinchilla with around 20 to 30 millimetre in 24 hours on Saturday.”
The deluge isn’t expected to let up until Sunday when the trough moves offshore.
Deluge to hit Victoria and Tassie
Victoria also won’t escape the wet weather with showers set to fall from Thursday.
“Widespread totals of probably around five to 10 millimetres will fall across the state with some isolated falls of about 20 to 40 millimetres and that's probably a bit more likely in the west on Thursday and Friday,” Mr Schmidt said.
Once the trough and weather system moves through, a low pressure system is set to re-intensify off the southeast coast.
“So on Saturday and Sunday we could see some relatively heavy falls of about 30 to 60 millimetres to the far east coast of Victoria in the Bairnsdale area,” the meteorologist explained, “as well as shifting into eastern Tasmania, which will see some pretty heavy falls as well on Saturday and Sunday.”
Sydney edges closer to rainfall record
While those competing in Sydney’s City to Surf on Sunday hold their breaths, forecasters believe the rain will dry up by race day.
“Friday and Saturday are probably the most likely days we will see rain but probably totalling maybe 20 millimetres, if that, for the two days,” Mr Schmidt said.
“It’s looking pretty good for Sunday.
“It’s still looking a bit cloudy, there might just be a very light shower or two, more likely in the afternoon, but all in all, it's not looking too bad.”
The harbour city is well on track to smash its wettest year on record.
So far this year, 1,966 millimetres of rain has fallen on Sydney, just 228 millimetres off the record set in 1950.
