Ha.
To be honest i could use anyone of 100 pics I've taken recently.
Light offshore. No swell.

Today is finally a bit different. Coolish east sou east wind and a rising swell.

Any station with poor exposure in a built up area will over-read in light wind conditions. That's painfully obvious when looking at Wunderground PWS's in built up areas.

The patterns are similar to August 1995 (endless high pressure) but the temps aren't a patch on that year, so far. Goulburn was regularly clocking 20C days in that heatwave, with a peak of 23-24. The warmest so far this month has been 18, equal to the Decile 9 max for August (1991-2020).

I think something is up at Bellambi. It is true that it may receive a bit of compressional (downslope) warming from the escarpment in westerly winds, but the same is true of almost anywhere in the Illawarra, especially Albion Park. Albion Park AP is itself warm in a westerly.

The Carolinas are a good match for NSW in terms of annual average temp (Myrtle Beach is also the same as Sydney) and even rainfall, but the eastern US is generally much more continental in flavour with proper tropical summers- even inland- and the odd severe cold snap in winter. Southern Brazil is more like coastal NSW.
This map has always stuck to my memory, but yh Buenos Aires is our latitidual match as well. Although a very different dynamic there with a much colder South Atlantic and wide plains to the west of the city.

I agree with Portland VIC= San Francisco. That is almost a dead ringer. Portland does receive more precip though, especially in winter. Cape Town should be Port Lincoln. There are plenty of sharks in both places, too.

Elevated Italy would be OK for Bungendore I guess, but we don't have a bone dry summer. Northern Italy does get some storms, the closer to the Alps the better I'd imagine. But little in the way of troughs and lows of tropical origin which Bungendore does receive. I would still say southern France because of summer rainfall. Though parts of elevated central/northern Argentina might work too, since I'm close to the border in that map.

That map is actually quite reasonable, although where is Tassie? Tassie would resemble Oregon or perhaps central France.

Strong seabreeze at B2, gentle zephyr in almost opposite direction at B1 where it's fine, mild and sunny.

Another beautiful day. This long spell of warm, sunny weather has brought the water dragons out of their hibernation, a couple of weeks early.

While today seemed similar to yesterday apart from a bit more cloud, the pattern of maxima across Sydney was different. OH was the cool place to hang out, maxing at just over 20°. The Airport, 3° cooler than OH yesterday, was a degree warm today. Away from the coast it reached 22-23°.

The difference was the light NE sea breeze today. OH is cool in a NE’er, the Airport is a bit warmer and it gets warmer inland where the sea-breeze influence wanes.

Looking forward to 27° on Monday before Winter’s inevitable return.

What's a "streak"?

Thredbo Top came back online yesterday.
Nobbys Head lost the temp & humidity/dp readings about 48 hours ago.

Seems like there always has to be at least one AWS playing up.

Thankfully the proliferation of pws data makes machine learning regression possible in most of these cases.
Maybe not for Thredders Top as I cannot seem to find historic data from the cohort private weather stations at Perisher and Charlotte Pass. They display current data but that's all I can find.

BOM have increased the amount of precipitation for CTs to 50 mm and lowered the snow level to 1000M for Tuesday.
Hopefully a good top up for the tank and some white.
They've left themselves quite a bit of room to go lower IMO.
Easily down to 900m on CT's IMO.

Settling in Crookwell etc.

EC and GFS are still holding out the possibility of some wet snow or sleet for the Highlands. Looks an ok setup for us.
Hard to say if the best chance is early tuesday or late that evening.

Tuesday night is reliant on that unstable airmass of the low, which will be fluky for low-level snow. I would suggest snow to low levels of ~800m etc would only be amongst those heavy precip bands (Tuesday eve).

Tuesday morning, however, has upper-level support for sporadic lo-lev snowfall.

Bom see's snow flurry's begin moving in along the ranges Monday night. With the furry's to continue into Tuesday moving up along the ranges in all the usual places such as oberon blackheath katoomba, orange bathurst, armidale and guyra with this type of cold system.

I am actually suprised a ECL will form given winter is nearly over and the Sea Temps are generally at there lowest. Around 18c at the moment. No doubt there must be strong upper support as previous fronts that have moved thru the last few months haven't really produced that much,

You can thank the June-like temps of the Tasman, with a broad field of +1.5-2C anom.
Highly supportive of cyc-gen.

+19C sea surface with neg air temps at ~1500m (850mb) that's some stiff lapse rate...

................................................................................
On the above posted bom ec charts by pow. 10pm tues plot displays the setup very well for a stinger jet in the tail . Hence why the EC going with huge gusts.
GFS lo-lev Vort & how about that directional shear....

Who'd think that in 48 hours it will go from this at B1 to half the temp? Answer - an algorithm with the correct data input.

Sydney rainfall for Tuesday now upped to 50 - 80 mm's with the chance of heavy falls.
Thunderstorms also included.
It's going to be a cold, wild and windy day.
Personally. The winds look a fraction too southerly for those falls in Sydney.
Will favour Hunter region.
