A few inland Sydney centres got late maxima too, adding about half a degree.

The air mass is not particularly hot now, but on Friday around 5:00PM, 850 temps over Sydney will be about 25, while they will be over 30 over North-Centra NSW. Forecasts are showing 6 consecutive 40+ for Nyngan, peaking at 44 on Friday. Forecasts for locations further South are cooler, maybe reflecting cloudy skies.

Seems like you have a nice location there Greg, I always like a mountain backdrop and Wollongong has no shortage of that either.

I think that forecast is too modest actually, it's more likely to top 45 or 46C there going by current models.

Was quite hot indeed today, just short of a rounded 35C, hitting 34.4C in the end at Moss Vale.

And a question for the day: Why are the Hobart Hurricanes called that when there are no cyclones there and more importantly, why are the Sydney Thunder called that when we don't get thunderstorms in Sydney, ever.

Tonight is the most pleasant night I could ever imagine here with 25C and a breeze from the NE. One thing I really like about this area is the fact there is almost always wind at night. Where it drops off after sunset at home, it keeps going all night up here. Usually it is a very cold breeze even in summer but when it is a mild one like tonight, it is literally perfection. It's the same temp at Albion Park but yucky humidity, at least when it is not humid this temp can be fairly okay for sleeping.

I got back to Lightning Ridge yesterday just in time for the next burst of 40 degree plus weather. Walgett has 40, 42, 44, 43 and 43 forecast for the next few days (like Nyngan that Steve777 mentioned). Yesterday Bourke was predicted to reach 47 on Friday, but that has been downgraded to "only" 45. But those forecast maximums could go up again depending on how conditions develop (as Wave Rider mentioned). But definitely as Steve777 mentioned central west and north west NSW look to be the focal points for the hottest air. I suspect there will also be some very high minimum temps over the next week, so sleeping may not be the best in many areas.

NSW has certainly trended toward being warmer than normal since about mid December (even though north-west NSW had a very hot period in late Nov/early Dec) and it appears the synoptic situation for the coming week is somewhat similar to what has resulted in the heat over previous weeks, with a "blocking" pattern. Blocking high pressure system in the northern Tasman combined with a broad surface trough down from the tropics through QLD and in to NSW directing a constant NNW airflow, whilst frontal systems from the south are effectively blocked from entering the mainland, hence whatever southerly changes there have been have tended to be somewhat weak and haven't cooled the temperature too abruptly or strongly.

I've also noticed the bursts of heat in NSW have coincided with the onset of the monsoon trough, so I'm guessing the monsoon trough has served to push an enormous amount of tropical heat southward and parked it over NSW, which may in part explain the warm upper temperatures, warm minimum temps, cloud cover, very warm temps even under cloud and the weak southerly changes, even near the coast. Anyway that's my theory :-)

Now you know exactly what I've been banging on about for years regarding that wonderful easterly that comes into Kalkite during the evening.
It's mother nature turning on the air-con.
It's just beautiful.

Yeah Greenfields maybe the monsoon trough has something to do with it, not too sure. One thing I do reckon, those consistently warm upper temps are the reason why we have had no decent rain or storms in months. The bulk of the rainfall lately has been coming from low level southerly changes which under cut warmer air above and rain is only caused by high humidity.

I've never seen it so dry here, all the grass on the farms around here is yellow and lifeless, and not growing either. The Christmas beetles are also attacking the leaves of the eucalyptus trees so it's a double whammy of stress for them. A heavy thunderstorm will apparently make them fall to the ground and then they drown.

Yeah Homer the easterly is awesome, although I prefer when it's not cold like usual. smile Very warm here, temp sensor says 23C and we have a light NWly. High Range even warmer at 25C and Moss Vale is at 18C. Going to be very hot here today and it'll start early. Just been outside in the mild conditions watching the beautiful colour in the clouds, took a few photos as well.

Another warm sunny morning here, Mt Horrible clear and the cicadas in full throat. It really feels like summer. My prediction for storms in the central west last week turned out wrong, just a few down south of canberra. Chance of storms predicted today mainly in the south. Even if a storm doesn't get me it would be nice to get hat cool downdraught of air you get from a near miss.

Already 30C up here with cloudy skies so if it was sunny it'd be even warmer.

Now at 34.3C and rising.
With the very late maximums we have been getting, the forecast is looking well on track today.

Sunny, warm and humid in Sydney. The sea breeze is now established in Sydney's East, dropping OH by over 3 degrees after just missing 30 shortly after 11:00. Sydney's outer West is now closing on 37, while the middle ring has dropped back a little after peaking around 31-32. The winds early were light and all over the place early, mostly Southerlies, before resolving into Easterly sea breezes.

There's hot air about. Mt Boyce is on 32, equivalent to 39-40 at sea level.

You can see some cloud development on the Western horizon, but there's nothing on the radar yet.

There are clouds bubbling up here, looking more promising than recently. The temperature has dropped back a couple of degrees after getting to 35.

We reached 34C here today before some cloud and a heavy shower just now. A very nice reprieve from the heat, down to about 24C currently. Can hear thunder right now as I'm posting this. Some nice rumbles too. There's a storm to the north now.

Friday is looking more like a mega scorcher than ever with the heat edging closer to the coast in every model run. Bowral is now looking at a top of about 37C at this stage. Western Sydney looking at low 40's but if the hot air mixes down, 45C is a possibility.

Storms developing at oberon and katoomba, looks like there might be something forming around Yetholme. The temperature has spiked at my place, now up to 39.

It's so painful, I'm literally right on the edge of a big storm. If I was working in Mittagong it would be awesome.

Looks like the development at yetholme has fizzled out a bit,but now there are storms just east of lithgow. More cloud at my place and the temp has dropped back to 36.
