LESS than 3mm of rain fell on Sydney this morning. Despite it sounding like not a lot — it wasn’t — it was actually the most moisture the Harbour City has seen for seven weeks.
But forecasters have said it is a mere taster of what’s to come with parts of NSW and Queensland due for “the heaviest rain so far this year” over the weekend.
It’s been labelled a “substantial rain event” which will provide some relief to drought-stricken farmers, particularly in northern NSW.
A low pressure system is working its way up from South Australia into the eastern states. As it gets closer to the sea on Friday, the rain dumps are likely to begin, with the ACT and parts of Victoria also seeing some showers.
“The low pressure system is, at the moment, over the central inland. It’s not causing rain in that area because there’s no moisture there but as it moves east it will move into moisture from the Coral and Tasman seas which is why NSW and Queensland will get the rain,” Sky News Weather meteorologist Tom Saunders told news.com.au.
Around 15-40mm is expected to fall in a band from southern NSW up to the Sunshine Coast with Wollongong, Sydney, Newcastle, the Gold Coast and Brisbane all experiencing a wet weekend.
Up to 60mm could fall across the North West Slopes and Plains.
“There will be rain and thunderstorms, some of which could be severe. There could even be flash flooding,” Mr Saunders said.
“Some areas could get their heaviest rain so far this year. If they get 29mm in Tamworth, that will be its heaviest.”

That 25mm of rain could be the heaviest of the year so far shows just how dry 2018 has been so far. Nonetheless, NSW certainly needs it. Just in Sydney, the city has seen 508mm of rain in total in 2018. That’s 400mm below the average.
“It’s 100 per cent the driest winter and driest start to the year for 50 years,” he said.
Over the next four days, up to 27mm of rain is forecast for Sydney, 30mm for Coffs Harbour, 35mm for Tamworth and almost 60mm for Moree.
In Brisbane, up to 40mm of rain is forecast with a possible storm on Sunday with similar conditions on the Sunshine and Gold coasts.
Canberra could see around 15mm falling. In Victoria, the showers will be smaller but expect getting on for 10mm in Albury for the weekend. Melbourne will be mostly sunny with a smattering of rain possible on Sunday.
