Can't remember who said it recently about Perth having Sydney's typical winter and Sydney having Perths'. Or something like that. Was it you Homer?

Nah. Wasn't me but I remember reading it from someone else.
That statement has a slight deal of truth about it though.

Perth had like 173mm of rain in July, and rained 24 out of 31 days. The average max was 18.4C, which was spot on average.
Can't really see the comparison.
Sydney has had some big rain events in August in the past, and June is a wet month, but July is generally dry.

Anyone know why the highs keep hanging off southern Qld/North NSW coast this time of year. Very much a summer heatwave set up. Is it water temps or something.

It was Steveman if I remember correctly.

Having the highs that far north is good actually, better than them sitting well below us. The only drawback, of course, if that it can drag some pretty extreme heat (relative to time of year) down to our part of the world. But we should get some useful cold fronts if this pattern continues too.

That was me back in July. Noting that in the month so far (July), Perth had been very cloudy (4 hours per day) and had recorded measurable rain on nearly every day, I said that Perth was imitating Sydney in March. Meanwhile, Sydney, almost rainless and cloudless this July, was imitating Perth in Summer.

Ok Steve. A fair call too. They are getting front after front now in the south west. Lucky buggers

Certainly an interesting comparison Steve.
July had bugger all rain, and only 0.6mm of rain locally.
Sydney has only ever had 1 month of 0.0mm of rain, August 1995, whereas Perth it is normal to get nil or negligible rain from December to the end of March. (sometimes well in April before the drought breaks)
June was an interesting month in Perth, highest average monthly maximum in 23 years of records, with just 2 days of heavy rain almost making up the average rainfall:

It is a different world up there in the Northern Rivers, they would beat Sydney winter records just about every winter.
The station to watch is Evans Head, just snuck back a little bit from the coast on some RAAF bombing range, it seems to be the hot spot.
Places like Yamba I do not trust, it used to have the August record prior to 2009, but it was pretty much hidden from view. (maybe Blair could find this record).

Perth has a Mediterranean climate, so it receives most of its annual rainfall from winter cold fronts and associated convention.

A typical Perth winter is mild and wet with occasional dry spells. These occur when strong high pressure systems form summer-like positions to the South blocking out the rain-bearing fronts. This happened during June.

A typical Sydney winter is dry and mild with occasional wet spells. These occur when East Coast Lows spin up over the Tasman Sea or when strong high pressure systems form summer-like positions to the South directing onshore winds onto the coast. Neither of these set-ups have occurred this year, so we've had an extremely dry and mild winter.

I think that the point was - if Perth is having wet wild winters Sydney can expect drier warmer ones and vice versa? And given the synoptic setups required for both, that would ring true to a large extent (with of course the usual variability of weather).

GFS is now showing a significant cool change passing through the State on Thursday / Friday next week, after which the blue line stays North of Sydney for several days. It features a high in the Bight, elongated North to South, directing cold air from the Deep South over NSW.

This morning's access provides some support.

It would be cold enough for Central Tablelands snow if this comes off, although once again moisture seems to be lacking North of about 35S.

It's very early days, usual qualifications.

The new BOM forecast has backed off heat for mid next week for the Sydney area, now going for 25-26 across Sydney. A weak Westerly change arrives in the morning. GFS shows 850 temps peaking around 14 over Sydney overnight Tuesday / Wednesday, then dropping away to about 9 by 10:00 We'd 16th.

EDIT: For short version, see Jimi above.

EDIT2: It's still on for the North Coast, 30+ next Wednesday North from about Kempsey.

All models surprisingly bullish about the depth of the change, as mentioned lack of moisture is an issue at this stage. The 540 line on GFS pushes right into southern QLD! Now if we can arrange some moisture, it could get interesting.
