YOU can normally rely on Perth to deliver solidly sunny and dry weather. Not at the moment. The city has just sloshed its way through its wettest June day in more than three decades.

And yet despite the torrential downpours, the Western Australian capital is still struggling with a distinctly dry June.

More torrential rain and even flash flooding is expected in the state on Thursday night while a cold front could bring some chilly days and snow to parts of the south-east towards the weekend.

In the 24 hours up to 9am Thursday, 61mm of rain fell on Perth. That’s around one third of June’s usual rain in just one day.

“This time of the year is the wettest for Perth but 61mm of rainfall is the heaviest they’ve seen on a single day in June in 31 years,” Sky News Weather meteorologist Tristan Myers told news.com.au.

A low pressure system is the culprit. Previously off the coast, it headed to shore right over Perth bringing downpours and storm surges.

While the rain may have eased in Perth, you don’t have to go too far to run into it again. In Wandering, south east of the city, 86.4mm of rain fell between 9am and 4pm on Thursday.

The Bureau of Meteorology issued a severe weather warning on Thursday afternoon for heavy rainfall and flash flooding for the evening and into the night south of the capital.

But despite the rain, Perth is still parched.

“To illustrate how dry Perth is, on average the city has 15 days of rain in June and it’s only had four days. In fact, it’s the warmest start to winter on record for Perth,” said Mr Meyers.

“Before this downfall, Perth had just 26mm for the entire month and the average rainfall is 173mm so this it’s very welcome and but well below average.”

With a total of 88mm for the month, Perth has to find 85mm of rain in nine days to even hit the usual level of June showers.

That was unlikely, said Mr Meyers. A few showers were possible but a change in wind direction going into the weekend, with breezes coming from the interior, will bring drier conditions.

If you want to really feel the winter weather head to Tasmania, Mr Meyers said.

“There’s a pretty strong cold front hitting Tasmania and that could bring snow as low as 500mm on the west coast ranges and Mt Wellington.”

Elsewhere, it’s a case of carry on as usual. A high pressure system over Victoria, NSW and South Australia will continue to dominate this weekend.

There will be the odd shower here and there and sunshine peeking through the clouds.

Head further north and you can expect dry and sunny winter days this weekend in much of Queensland with showers increasing as you head into the tropics.
