Soggy start to the new year with heavy rain set to spoil NYE

Sydneysiders could be in for a wet start to 2021 with early modelling suggesting heavy rain on New Year’s Eve and New Year’s Day.

Weatherzone meteorologist Ben Domensino told Yahoo News Australia early modelling shows heavy rain throughout NSW to begin 2021 and end 2020.

“In the broad set up what we’re seeing is a low pressure trough moving across eastern Australia before meeting a stream of moisture in the north,” he said.

“It’s similar to what we saw at the start of this week. Some parts of northern NSW received heavy rain. Tamworth got 90mm.”

Tuesday was Tamworth’s wettest day since 2012. Nearby Walgett was saturated with more than 38mm across Monday and Tuesday, according to the Bureau of Meteorology.

Parts of Northern NSW including Evans Head received about 32mm on Sunday.

Mr Domensino added if the models are correct these areas could see some flooding.

Wet start to 2021 for Sydney

Early modelling suggests Sydney could receive 30-40mm across the start of the new year.

Mr Domensino said Brisbane will be largely unaffected by the wet weather though with “Sydney more likely to be impacted”.

Southern and western parts of Queensland could receive heavy rain.

In Western Australia, the Kimberley region, which has already copped a deluge, could be in for more rain too along with other parts of northern Australia.

“They will be stuck in this weather pattern going into the New Year,” Mr Domensino said.

Mount Elizabeth, north of Broome, was hammered with 74mm on Sunday.

Mr Domensino said the modelling is still in the early stages though but a few different models are suggesting a wet January 1.

“It will all depend on how that trough develops and we’ll have more of an idea heading into the end of the week,” he said.

The model also suggests little if any rain for Melbourne or Adelaide.

Meanwhile Christmas Day will see a mix of warm weather and rain across the nation. Perth will swelter through 35-degree heat, while Melbourne and Sydney will be much cooler with 21 and 23 forecast respectively.
