Cold snap sends tremors to southeast during north swell awaiting monsoon

The southeast trembles with intense cold spells, while the north swells with another episode of stormy weather in Australia.

The calendar might say there’s only one more week of summer left, but that’s certainly not the case in the Southeast today.

“When you think it’s mid-June, it’s actually late November,” said JMA forecaster Jonathan Howe.

Maximum temperatures will be 5 to 15 degrees below normal across the Southeast.

The unseasonably cold weather is due to incredibly cold air rising to the southeast.

“From the very south of the country, they have come a long way to be with us,” Howe said.

But perhaps what you’re really feeling is the wind chill.

“For example, we had a shower in Melbourne at lunchtime,” Howe said.

“At Tullamarine, Melbourne Airport, the actual temperature dropped to about 5-6 degrees, but the wind chill made it feel like -7 degrees.”

A damaging wind blows through the southeast.

“There are warnings for the southeast, southern Australia, much of Victoria and southeastern New South Wales,” he said.

“We are already seeing widespread gusts of over 90 kilometers per hour, including around Melbourne and the Illawarra coast today.”

Tasmania could get more warnings tonight with snow.

“Some alpine resorts have seen decent snowfall, but some ranges around Melbourne, including the Macedon Ranges, could see dust,” Howe said.

“Throughout tonight snowfall will drop to 500-600m in Tasmania and 800-900m in Victoria and southern New South Wales as cooler air passes.”

Brisbane, by contrast, was expected to pose an extreme fire hazard with temperatures soaring to 35 degrees Celsius today.

When will my cold go away?

Thankfully, today looks like the coldest and windiest day for most people… unless you’re in Tasmania, tomorrow is the day to sit down.

But even with the worst of the cold snaps gone, temperatures aren’t expected to rise until Thursday when warmer air begins to move in from the north.

“Friday looks like it will be the choice of the week, with temperatures close to average in Adelaide, Melbourne, Hobart, Canberra and Sydney, or above average in parts of South Australia,” Howe said.

Any updates on the flood?

This latest round of stormy weather has fortunately missed most of the areas experiencing major flooding at the moment.

The Lachlan River now peaks near Forbes and Condovorin, but its waters still flow downstream to places like Ure Barron and further down to Hillston.

Meanwhile, Murray itself is still rocking.

According to Howe, “we’re seeing water rise in places like Murray, like Mildura.”

“Most of that water actually flows into South Australia as it passes through Mildura.

“Some parts of South Australia are already experiencing minor to moderate flooding.”

This will get worse as more water heads downstream.

“We’re just reminding people to stay in touch with SES and local road conditions as the rivers will start to rise in the next few weeks,” Howe said.

The build-up is in full swing in Kitakami, but if we’re lucky, it’ll be over soon.

There was a big storm in the north during the night.

130mm was recorded at Mud Springs in Kimberley and 97mm at nearby Mount Claus.

The storm has spread across parts of the Northern Territory and into northern Queensland, with massive hail in central Queensland yesterday.

“During this next forecast period, we confirm that the Madden-Julian Oscillation will migrate to the Australia/Indonesia region,” Howe said.

“So this means an increase in rainfall and storms, which is exactly what we’re seeing in the north of the country.”

However, the heat wave conditions will continue until the rains are adequate.

According to Howe, “These have been going on for quite some time.

“So I’m sure many locals are waiting for the proper start of the monsoon.

“We hope the heat wave conditions will ease heading into this dry season as showers and storms are expected to become more widespread heading into the weekend.”

A proper monsoon usually starts around mid-December, but may start earlier as La Niña is in full swing.
