No mention of showers for Sydney in the forecast today yet plenty are entering the basin from the south??
Yeah I did see that too, but to be fair none of the Sydney basin stations had any recorded rainfall from those showers which disintegrated pretty quickly. So I'd call that at least a pass for BoM.

Quite an interesting weather situation happened last night and early this morning which the NZ Met Service shows quite nicely, and it explains the showers which occurred on the south coast as that low spun up an occluded front.
12am chart (NZ time I assume).

And then you see that Sydney just got clipped by the tail end of it on the 6am chart, and therefore the showers quickly fizzed out.

That light precip on radar around the Central Coast which is likely virga, is possibly the last remains of this front before it quickly moves eastward, as seen in subsequent charts).

A very bleak afternoon in Sydney, dark with a few spits of rain. The temperature maxed at 18-19° during sunny breaks around lunch time.

A clearing edge is approaching, however. We might be in for a nice sunset (5:35 PM). I don’t think there’ll be any thunderstorms.

Sunny with warm afternoons for the last two days of Winter.

22 degree halo around sun for most of the morning. That's what Cirrostratus does to sunlight. Considering it's a post- frontal airmass it's not too cool - in the sun.

August 2021 has been mild and sunny in Sydney, with average minima and warm afternoons. Mean temperatures ranged from 9.8° to 20.7°, that’s +0.1° to +1.4° with regard to recent averages (1991-2020). All but 8 days reached 20°, just three failed to reach 16° and one was the coldest August day in 25 years. Most minima were below 10° but none were particularly cold, with the coldest a relatively mild 7.9°. Rainfall finished about average, 81 mm vs 75 mm (median 46 mm). Nearly all of that fell from about 11:00 PM on the 23rd into the small hours of the 25th.

Bankstown finished 6.5° to 20.6° for anomalies of +0.5 to +1.5°. Rainfall was 66 mm compared to an average 50 mm.

August 2021 Summary

IV72UZb.jpg


A warm, dry, and uneventful month—in stark contrast to July. Only a single (light) snowy day as opposed to 7, with an entire lack of true frontal systems or even a proper NW cloudband.

Anomalies @ Hunters Hill (1993–2020)

• Mean Maximum = 9.1° C (+0.2° C)

• Mean Minimum = 3.1° C (+0.6° C)

• Precipitation = 92.8 mm (67.5%)

Anyone else thinking it looks floody for inland NSW this weeekend? Murray and Murrumbidgee in particular, but more for the Lachlan also.
NW cloud band + trough + cold front.

Do think the models tend to overcook these numbers over inland regions from this type of setup.

Though it does look widespread and solid enough.

Tropical feel with palms blowing in the humid breeze. And it's only Sept 2nd.Cloud clearing as forecast. B2 offline last 2 hrs.

Hopefully the BOM might be sorting out the problem with Bellambi, though I'm not sure if it qualifies as essential work.

Certainly a warm season pattern at the moment- lazy high in the Tasman with the locus of the heat on South Australia. Mount Lofty has hit 25C, which is the latitude and altitude equivalent of Bungendore, though average maximum temps are usually significantly cooler at Lofty (with minima much higher). Potential extreme maxima are probably the same, though. I think 25C here in early September would probably be a record and indeed it may be the earliest 30C in Adelaide on record, according to Weatherzone. It reached 24C at Goulburn during the August 1995 heatwave.

It isn't forecast to get that warm here tomorrow, suggesting the slight NNE'ly flow is enough to attenuate some of the warmth.

B2 is coolish with low cloud and part sun
Moderate breeze off the ocean as well.

It felt very humid and sultry today with those NE winds, haven't felt that in a while.

For me winter was split into two halves - June and most of July felt quite typical - cold, cloudy and drizzly. Early-mid July was especially cold. Then August was warmer and very stable - no real weather except for the rain on the 24th.

There were no really cold nights either. Overall not a very memorable winter, especially compared to the cold one in 2015 or the super frosty but sunny 2017/2018.

Same here on the Central Coast. August felt very different to June and July. I'd say winter started with that cold snap on May 15th and ended in early August.

Nice little warm spell right now for the start of spring, up until Sunday anyway.
26C days are quite toasty, nights still cool but not as cold as early in the week.
Winter wasn't particularly memorable here either.
Maximums about average, and minimums slightly below average, although not a lot of frosts compared to some years.

It does look like a “mini event” coming up on the weekend, an echo of the recent one back on August 23-25. A trough and cold front cross the State, bringing extensive, useful rain to inland areas, especially in the SE. Once the system hits the Tasman, it spawns a low off the central part of the coast. This time, however, the low doesn’t suck in very cold air, so there will be little or no snow outside alpine areas. The low moves quickly away out to sea, so the event is short-lived.

Expected rainfall:
* Sydney: 20-40 mm
* Canberra: 29-45 mm.

Lets see if it bombs, with the 24 hr pressure fall needing to be 14hPa at 30*S, 16 hPa at 35*S and at 40*S 18hPa. Looks like it will give the South Coast the rain rather than the North where it's more needed.

Definitely feeling the humidity the last couple of days. Nothing compared to mid-summer but feels more humid than it has for months here.

near sydney CBD.
Maybe in the afternoon tomorrow we will see this style of rainfall (20mm in 10min) with no flooding.


That video that i found on youtube was taken a few days before the great western sydney supercell of 2007.

That 2007 supercell was very similar to the 1947 supercell that it was capable of being strongest on the coast but sadly is was heading in the wrong trajectory and missed the CBD

The models have downgraded the coming event. The low now forms off the South coast, moves a little to the North East then quickly scoots off towards NZ. Rainfall totals for Sydney are now down to 14-25 mm, this amount falling between about 1500 Saturday and 1200 Sunday. Snow is still a possibility above 1200 metres on the Central Tablelands.

There have been some good falls across the West and South of the State, including nearly 43 mm at Canberra.

It’s been solid overcast all day here, warm with periods of filtered sunshine this morning and cooler with steady light rain from mid-afternoon. Falls across Sydney have been mostly around 5-8 mm so far.

I've had light, but steady rain (with big drops) for over 7 hrs now. I'm surprised the totals are so low.
