Weather News - SA, NT, QLD, NSW a bit nippy for early winterBrett Dutschke, 22 June 2019
Parts of Australia's south, centre and east are enduring a run of unseasonably cold days and nights, colder than any time in the past several years.
We haven't even reached the coldest part of winter and frost has already become widespread and in some parts severe, and this has persisted for several days now. Temperatures have been dropping seven-to-11 degrees below average.
Today is the coldest it has been in 37 years at Coonawarra (-3.8 degrees) in South Australia, 12 years at nearby Mt Gambier (-2.2 degrees) and Birdsville and St George in Queensland (0.5 and -2.9 degrees respectively) and Moree in New South Wales (-3.8 degrees) and eight years in SA's Coober Pedy (0.8 degrees) and Naracoorte (-3.8).
Recent fronts have been void of significant moisture, in fact have been unseasonably dry, only bringing showers to far southern parts and snow to the alps. This very dry air has since been covered by a slow-moving high pressure system which has cleared skies and allowed any daytime warmth to disappear at night. As a result, much of the region has chilled to temperatures more typical of July or early August.
The chill is not over, expected to continue through to at least Monday due to the very slow-moving nature of a stubborn high pressure system.
Coonawarra can expect to get similarly cold on Sunday and Monday mornings. There is potential for the grape growing area to extend its run of mornings dipping below minus two degrees to at least five, a feat which has not been experienced in the area in 47 years. And winter has only just begun.

Weather News - Heatwave and fire danger intensifying in SABrett Dutschke, 1 March 2019
The heatwave which has been affecting South Australia is intensifying along with fire danger as gusty northerly winds kick in.
As of about 2pm it had become the hottest March day in 33 years in parts of Adelaide, including Kent Town (41.7 degrees), Elizabeth (41.6 degrees) and Parafield (42.0 degrees), and it is not even the hottest part of the day yet.
The highest fire danger has been in the west of the state where some areas have experienced Catastrophic fire weather. With a peak expected in the next hour or so, fire danger is already at its highest for March in 10-to-15 years at Minnipa, Cummins, Adelaide and Naracoorte.
The hot, dry, gusty winds will ease later this afternoon but stay gusty enough overnight to keep temperatures across much of the state into the thirties well into the night ahead of another scorching day tomorrow. Adelaide is likely to be warmer than 30 degrees after midnight before reaching about 40 degrees again tomorrow.
A cooler change is due top reach the state's west late on Saturday then slowly cross the rest of the south during Sunday, not reaching the far north until mid-next week.
The change will initially be a dry one, rain only beginning to fall late on the weekend and into early next week. This rain looks fairly patchy and is sure to contain some thunder.

Weather News - A trifle nippy for this time of year in Australia's southeastBrett Dutschke, 31 March 2019
Parts of southern Queensland, New South Wales, Victoria and Tasmania were five-to-10 degrees colder than average overnight and had their coldest March night in many years.
It was the coldest March night in 35 years at Cobar, dipping to 6.5 degrees, coldest March night in 32 years at Hobart Airport (3.4), and the coldest March night in at least 20 years at Eildon (4.0 degrees), Cabramurra (-1.3), Moruya (3.8), Mount Boyce (3.0), Sydney Airport (11.5), Terrey Hills (9.8) and Toowoomba (9.3).
Even the Sydney and Brisbane areas felt the bite. It was the coldest March night in 14 years in Sydney city (12.5 degrees), 11 years in Brisbane City (15.3), Horsley Park (8.0), Bankstown (9.3), Ipswich (10.4), Brisbane Airport (13.0), Archerfield (13.9) and Redcliffe (14.4).
One of the coldest places in the country was the on the snow-covered top of Thredbo where it recorded a minimum temperature of -4.2 degrees, an 18-year low for March.
And for much of southeastern Australia winds were fresh and gusty enough to make it feel even colder for those outside at the time.
One of the strongest cold fronts since last spring was the main culprit. It brought the heaviest and most plentiful showers in three-to-four months to parts of South Australia, Tasmania and Victoria and scattered snow on the Tasmanian highlands and as low as about 1200 metres on the Victorian and NSW alps (as much as 10-15 centimetres worth nearer the peaks). A high pressure system had squeezed its way in to partially clear skies and cause wind to ease somewhat, allowing to get so cold.
The high will lead to another chilly night or two ahead but most places are unlikely to get as cold as last night.
