Heat surge set to hit Australia
If you live in a place that received snow this weekend and were hoping for a repeat of the glorious conditions any time soon, we have bad news.
While the polar air will indeed linger for the next few days, a burst of warmth is about to hurtle its way towards the south east from northern Western Australia just in time for the last weekend of winter
That will likely see the mercury rocket by 10C in Sydney, from a maximum of just 16C on Tuesday to 26C on Sunday.
Melbourne, Adelaide and Canberra could also see temperatures rise as the week progresses. But it will be a brief bump for Tasmania where a cold front will send the numbers right back down again.
Across the east of the nation, frost will be a menace first thing through the middle of the week.
In Perth, a settled week of pleasant winter weather and cold mornings.
Prepare to rug up tonight as there could be a chilly start to Tuesday. Temps in some parts of NSW could be 2-6 degrees below average. The Alps might even get to minus 9 tonight...brrrrr!#NSWweather https://t.co/9RsKNN8YqH pic.twitter.com/nCKUiBHKfF— Bureau of Meteorology, New South Wales (@BOM_NSW) August 24, 2020
"We still have polar air lingering across south east Australia but on Tuesday the colder air will start to contract towards the east," said Sky News Weather Chief Meteorologist Tom Saunders.
An area of high pressure will replace the Antarctic air bringing clear skies.
"As the maximum temperatures climb, the minimum temperatures (around dawn) will drop thanks to those clear skies and light winds. Many areas will be close to or well below freezing particularly on the ranges."
Tuesday, Wednesday and Thursday could see frost over a vast area of New South Wales, southern Queensland, central and northern Victoria, eastern South Australia and parts of Tasmania.
Coastal areas across the east, as well as Melbourne and much of southern Victoria should be spared due to cloud cover.
Then, as we pass midweek, it begins to hot up.
"We have some record winter heat in northern parts of Western Australia and as winds blow clockwise around highs, so the warm weather will be drawn across the south eastern states."
In parts of the north of WA temperatures are 12C above average.
WEATHER AROUND THE STATES
For Melbourne, a high of just 13C on Tuesday will rise to 21C on a sunny Saturday but could drop back into the mid-teens on Sunday. Colder mornings earlier in the week of just 5C rising towards the weekend. In contrast to recent days, just the odd spot of rain.
Similarly chilly in Canberra. On Tuesday it's likely to reach just 12C with a bone chilling -4C on Wednesday morning. But come Sunday it will be a sunny 18C with dawn starts of 6C. Frost will be a feature up to Thursday. Clear skies mean no rain.
Dry in Sydney too this week. The 20C barrier should be passed on Thursday with 26C on Sunday but then a drop to 18C next Monday. Nights will still be cold, though, bottoming out in the single digits.
Away from the coast, the mornings will be teeth clatteringly cold with -1C on Wednesday in Wagga and -4C in Katoomba and Orange.
Adelaide will see 16C on Tuesday but 22C on Saturday. Like Melbourne, it's a bit of a see saw with the mercury back to 16C on Sunday. A cold 5C start on Tuesday but an almost warm 12C early on Saturday.
A cold front will keep it wintry in Hobart with a high of just 13C on Tuesday and not much warmer for the rest of the week. A brief touch of heat on Saturday, when it will reach 20C, will rapidly fall to a maximum of 13C on Sunday.
A low of 2C for the Tasmanian capital on Tuesday and then 7C for much of the rest of the week.
Temperatures will inch up in a mostly sunny Brisbane from 22C on Tuesday to 24C on the weekend with lows hovering around the 10C mark.
While the southeast shivers, western and central Australia is experiencing unusually warm conditions with maximum temperature 4 - 12 °C above average. This #heat will extend east through the week.

Scorching in northern WA. Fitzroy Crossing is likely to see 38C all week although overnight it will only reach the mid-teens. Cooler on the coast, but only by a touch, with 31-36C at Port Hedland. It's that heat that will be heading towards the south east.
Much more manageable in Perth with 3pm maximums of around 20C - possibly up to 23C on Thursday. Lows should be around 10C.
Very hot in Darwin. The Top End city is looking at 36C on Thursday and 34C on the weekend. Cooler at night though with temperatures falling to only 20C on Tuesday morning.
