Smithville is a cattle station on the SA border about 220 km NNE of Broken Hill and SW of Tiboburra.

Noona, Smithville and Borrona Downs (along with a few others) are all relatively new AWSs put in with NSW government funding. They were explicitly placed to fill gaps in the network so aren't associated with population centres.

The Smithville AWS is less than 100 metres from the border.

Wish they threw one in lake eyre. Would be interesting to see what negative elevation does to temps. Like death valley.

The temperature would be quite steady and unchanging a few months after a big rain event in western Queensland.
That is, unless they put it on an anchored bouy.

It looks like most of the basin got to 38-40, with only the far western suburbs above 40 today.

Canberra was able to just notch 40.1 today making 4 days in a row above 40, which is a record for consecutive day > 40.

Here are some other 4+ day heatwaves in Canberra of similar magnitude. Note that 1939 and 2014 had one day between the +40's that was a fraction off a degree from 40:

Jan 1939 (8th - 14th):
39.3
39.2
41.1
42.8
39.8
41.9
40.8

Jan 1952 (22nd - 25th)
38.2
38.2
38.7
38.7

Feb 2009 (5th - 8th)
37.8
40.3
40.3
40.3

Jan 2014 (15th - 18th)
40.2
40.1
39.7
40.0

Would be more humid than terry hills malfunctioning AWS.

Not sure the NSW government would be interested in funding a site in Lake Eyre :-).

I've actually had a look at the effect of floodwaters on summer temperatures (at a back-of-the-envelope level, not a rigorous scientific one), using cases in the last decade or so where places with observing sites were surrounded by floodwaters for an extended period (e.g. Kerang in January 2011). The effect was surprisingly small (assuming the site wasn't actually in the water), only a degree or so on maximum temperature at most.

1939 remains an outstanding event despite the duration and severity of this heatwave. Here our maxima have been 2 - 3° less than the BoM's predictions. Orange Airport surprises me however, with maxima only 0.5°C less than Bathurst, yet Orange is 250m higher. Evidently a steep temperature gradient in the upper layers from E to W. Records seen in the Snowy Mountains need to be put in context - Cabramurra doesn't cover 1939.

Temps at Penrith and Richmond are still rising. Penrith hit 42 a little while ago, Richmond not far behind on 41. Other sites in the outer West have maxed since 4:30PM.

Fair point re: Cabramurra. The only reasonably long-term alpine sites with data for January 1939 (and that only monthly, at this stage) have long since closed - Kiandra in NSW and Mount Buffalo in Victoria. (Kiandra may be close to Cabramurra in distance but is completely different in topography - the daily variations of winter minimum temperature at Kiandra correlate better with those at Alice Springs than they do with Cabramurra).

Phew the record for the Mount Boyce is still remaining where it peaked at 35.5 although cooling down now even though it is still under a westerly influence. Although a substantial month for that region already. Usually Mount boyce would have 4.4 days above 30 degrees they have had 10 already including today.
Blair would you know if any Wet Globe Bulb Temperatures records were challenged this heatwave.

Sea breeze has arrived at Penrith now. Looks like that's it 42.1c is the top.

This particular heatwave was indeed a rather South-Western NSW event—hence more adequate heat down this way than up north in the Central Tablelands at similar altitudes.

Hottest to Coolest; Snowy Monaro Shire:

Cooma Visitors Centre (778 m AMSL) = 39.5° C;

Cooma AP (930 m AMSL) = 37.9° C;

Anglers Reach (Here; 1,280 m AMSL) = 34.7° C;

Thredbo Village (1,380 m AMSL) = 33.0° C;

Cabramurra (1,482 m AMSL) = 32.3° C;

Perisher (1,738 m AMSL) = 30.1° C;

Thredbo Top Station (1,957 m AMSL) = 27.2° C

Storms are developing on the SW'ly change line near the coast. Wonder how this will go once it the basin. Looks to have quite a punch in it as well. Goulburn recorded a 70kmhr gust despite not being a storm.

Southerly winds have made it through the Vic.NSW border region and through Moruya Airport.

YAY Southerly is here!!!

Lol Kiama just reached its max temp (28°C) with the southerly change, not often you see that. Meanwhile the NEer could barely hold a 25 degree temp.

Looks like we're in for a nice run of weather for the next 5 days or so. A lot cooler but still plenty of sunshine. Even tomorrow is forecasted to be mostly sunny, although I think it will be a bit cloudy especially in the arvo with southerly winds and pretty high humidity.

Both the southerly and the SWerly can be visible on radar now. Check out Kiama's temps wind swung to the SW and it soared 4c in 10 mins.
