A huge dust zone stretched across the vast areas of New South Wales and ACT, as the furious cold front passed through the state, lifting the soil and sand from the inland, and plunging it further into the interior.
It's already covered with Canberra and the dust is heading for Sydney because the cold front is marching north.
Satellite imagery showed that dust flowing from NSW in an extensive band across the state down to the south coast. The living fake color map from the meteorology office showed that the dust cloud in NSW was a bright pink circle.
In Sydney, a sharp Tuesday came, which reached 36.3 ° C in the CBD and 38.3 ° C in Penrith, west of the city.
At 6:30 on Tuesday, Harbor City was still 34 ° C. In the northern parts of the country, fires occur in baking conditions.
Yet south of the border it's a very different story. At midday it was so cold that it was the second coldest temperature recorded this year in Melbourne – the first one at night.
While north of the border, storms collapsed to the southeast, while floods continued their inexorable march into the oceans.
Sky News Weather Channel meteorologist Rob Sharpe told news.com.au Sydneysiders should prepare to clean the dusty windscreen on Wednesday morning as a wave of dust drives the state into a fine red dirt.
"In the NSW there are dust storms that extend over very large areas from Queensland and South Australia near Tiboobur to the southern coast of Ulladulla.
"The strong cold front flowing in the southeast is picking up dust and it's easy to get to Sydney, most likely overnight."
That cooler weather probably arrives in the city around midnight, he said, who can drastically record a drop in mercury when Wednesday tries to reach the top 26C, 11 degrees below the high end.
Canberra will see 24C on Wednesday, and then mercury is likely to fall back to the mid-30s over the weekend.
Wind and hot conditions led to a fire in the north of NSW. Public fire service of the state said that at 19:00 51 burns and grass fires burned. Of these, 19 were present and two remained at the alert level.
To the west of Tabula there is an extraordinary lawn that warns that on Tuesday afternoon it can spread to the nearby settlement of Jubullo Aboriginal.
Alarm alert was also issued to people near the fast-moving bushfire burning south of Inverell in northern NSW, which has already burned nearly 1,000 hectares.
Firefighters and planes were unable to slow the fire that burns east of Lake Copeton and spread rapidly towards Tingha. Features are compromised.
The nationwide ban on the fire, which was released on Tuesday, was extended to Wednesday for the Northwest, North Coast, North slopes and the New England area.
In Queensland, a storm storming through the sunny coastline took place early in the evening.
To the south, Brisbane continues to storm when he tells Mr. Sharpe: "Brisbane got to 35 ° C on Tuesday, which is the 34th day after a row above 30 ° C, so it was just an extraordinary warmth.
"But we have reached the peak of the heat for Brisbane, Wednesday will be 36 ° C and then there will be a cold change on Thursday, not a big change for Brisbane, but it will be around 30C on Friday and Saturday.
CHILLY IN MELBOURNE
Then you were south of Murray, where the cold front was already going, and it's practically the weather on the scarf.
"In Melbourne, the cold change flew late in the morning on Tuesday with temperatures falling from 21 ° C to 15 ° C in just 20 minutes," said Mr. Sharpe.
"It even reached 12.7 ° C, which is where it is down and this is Melbourne's second coldest temperature this year, reaching 12.6 ° C (on February 1), but it was early in the morning and it was at noon and with a cooling factor would feel below 10 ° C. "
Snow was now developing in Tasmania at 900 meters, he said.
Wednesday is unlikely to be as cold or windy as Tuesday in Victoria, Tasmania or southern Australia with much quieter conditions.
"We'll see how the sun's rays get bigger and that the showers are down when they're moving all day long," said Mr. Sharpe.
Low 11C and high 19C in Melbourne with Hobart just a little cooler. Adelaide reaches 22C.
In Perth, expect a sunny height of 33 ° C on Thursdays and the same in Darwin, but with additional storms at the top.
