Bitter Cold Snap Catches Kangaroos On The Hop.
( source: Weatherzone )

A strong cold front is making its way north through New South Wales, having passed through Victoria overnight, accompanied by rain, strong winds and snow to low levels.
These kangaroos were caught on the hop by the heaviest snowfalls of the year outside the mountains, with up to 20 cm on the ground.

The picture was taken by a local at about 1100m above sea level on a property between the NSW towns of Berridale and Jindabyne – and while you associate Jindabyne with snow, the town lies below the regular winter snowline, and the snow doesn’t normally start until a good 10 or 15 km out of town as you head up to Thredbo or Perisher.
But this morning, some super cold air has enabled snow to fall to much lower levels. We told you yesterday that snow could fall to the following levels today:

Around 300 metres above sea level in Tasmania on Monday night into Tuesday morning

Around 500 metres in Victoria on Tuesday morning

Around 700 metres in southern NSW and the ACT late on Tuesday

900 to 1000 metres in central and northern NSW late on Tuesday

The first three of those predictions appear to have come to fruition, with snow falling to exactly 300 metres, according to a Hobart local who spoke to Weatherzone, although it wasn't settling on the ground until about 400 metres.

Meanwhile Canberra dropped almost five degrees in less than an hour as the cold front passed through this morning. As we write this story just before 10 am, it is a chilly 4°C with steady rain. Most of Canberra sits at or around 600 metres above sea level, so with snow forecast down to about 700 m, a few flakes in the capital are not out of the question.
As you'd expect from a cold, moisture-laden system like this, there has been heavy snow reported in the snowfields, with around 15 to 20 cm overnight at all resorts. As ever, the picnic-table-o-meter at Mt Hotham in Victoria tells the tale.

As for Australia's two most populous cities, Melbourne got a decent drop of rain with 8.8 mm overnight. It'll stay cold all day, with the mercury reluctantly edging its way towards double digits. A top of 12°C is expected.

You can reverse the numbers for Sydney, where a top of 21°C is expected with the mercury already reaching 20°C in suburbs by 10 am in bright sunshine. That'll change later today with a cold change and rain expected, so if you're in Sydney, enjoy the warmth while it lasts.

Sydney's coldest afternoon of the year!

Sydney reached a top of 23.2°C just after midday today, so August 23 was officially the equal second-warmest day of August 2022 to date. Then the cold front struck town, and everything changed in minutes. By 3 pm, which is usually pretty close to the warmest time of day in winter, it was just 10.2°C. Throw in the wind and rain and the "feels like" temp was a bone-chilling 1.8°C. For the record, the average 3 pm temperature in Sydney in August is 17.5°C.

This was due to a strong cold front that surged its way northwards, ushering in a cold airmass with polar origins. Southerly winds set in behind the front, dragging additional moisture towards the coast. Once the cold air had well and truly set in, persistent cloud and rain forced temperatures down even further.

hurricane season is so dead this year

Proves that it's not all about sea-surface temperatures. Climate change may be making dusty Saharan airmasses more prevalent in the Atlantic, which suppress tropical development.

BUT I THOUGHT CLIMATE CHANGE ALSO MADE HURRICANES MORE FREQUENT DUUUUUUURRRRRRRRRRRRRRRRRRRRRR

Increased atmospheric CO2 does not increase SSTs lmao. Oh my fuck what drivel are they teaching y'all today in school.

Yeah I know the peak is around early to mid sept and all it takes is one big storm to make a season memorable but it's been very poor for mid to late august 

Okay hold up, everyone has to take a look at this. Apparently China has been having the most absurd heatwave ever seen anywhere on earth this month, and no one has been talking about it. Chongqing, which averaged 33.2/24.7'C 1981-2010, and has an all-time record of 43.7'C (which was tied or set this month) has hit 40'C every day since August 8th and the month so far has averaged a fucking 41.4/32.1'C. The average low has been close to the normal high.
