Will we ever see another 50C in Australia?

And then equals its record max from any month with 48.5C at 12:45pm!
Interesting to see it equal the early-January 1990 heatwave. Worth keeping an eye on Eucla in WA too. 48.0c there so far today. It's all time record is 49.3c on 17th Dec 1912.

Is it possible to access temperature traces from BOM, that is temp vs altitude at say 8.00am? Then we can calculate the volume of air to be heated and have a better shot at working out the maximum.

This was/is the key briefing data at Waikerie during the gliding season but that was generated by the Gliding Club. There was one available from BOM I think from Parafield.

I might get slaughtered for this... Do electronic thermometers give higher peak readings than old-school mercury thermometers because they're more responsive?

The hottest air doesn't arrive until around 4pm South Australian time so we should have another 45-60min of potential rises in temperature as well...

So the maximum is recorded separately from the live data and can occur at any time. Live data is normally uploaded once every 10 min but can be more frequent in significant events, however the maximum is recorded precisely.1

eg, say it hit 50.0 at 13:34:19 then this would be recorded as the maximum even if it was 49.1 at 13:30:00 and 47.9 at 13:40:00

WZ gets its temp data from the BoM

that was my first thought but in amongst the 10 min readings is 12:23 49.7. it is the highest in there and one of only two not on a 10 min boundary. i wondered if that meant that it was the highest

Fair enough. I see the 50.0 in the screenshot now. I wasn’t aware AWSs did that as usually the max temp has an irregular timestamp
Ok Andrew Miskelly just contacted me on Twitter-

it may be an error with the WZ reporting, they may be showing an incorrect number of significant figures ...

Yeah, the plains north of Adelaide are sweltering today. Notable again is Parafield. It has records going back to 1939. Prior to this heatwave, its record December temperature was 44.2C. That was broken on Wednesday with a 44.9C. Then yesterday, it got to 46.3C by the afternoon! Today it hit 45.2C at 10:53. To add some perspective, yesterday at the same time it was about 4C lower (albeit the setup today is different and how high temps get will depend on timing of the cool change). Still, remarkable stats considering the long records.
