Usually not too much of an effect compared to further south. The odd enhanced SW flow and some cooler nights.
I dont think they have a sam type setup in the northern hemisphere? I noticed on the california coast, they just seem to get endless months or northerly winds when looking at windy and a constant high that sits between california and hawaii that never seems to move. So i cant see how they can have hot temperatures in LA when winds are form the north.

The northern hemisphere equivalent is the AO (Arctic Oscillation) @Gleno71

When it goes negative, the midlatitude westerly belt, storm systems, and polar outbreaks often tend to extend further south than usual. Vice versa for positive phases. It operates like the SAM.

AAO (Antarctic Oscillation) is also another name for SAM in the Southern Hemisphere.

There’s also other various more-regional oscillations in the northern hemisphere such as the NAO (North Atlantic Oscillation), etc.

LA actually doesn’t often get extremely hot temps but sometimes they do if there’s a decent offshore component to the winds or a big heat dome with a stubborn surface and midlevel high that sets up over the west of the country.

Do we experience "sundogs" in Australia?

Yes @Rays74 , sometimes. Mainly when cirrus is around and the sun's low in the sky at the time. But they tend to be more common in the very high latitudes of the northern and southern hemisphere e.g. Antarctica, especially when there's diamond dust around (lots of tiny ice crystals suspended in the air caused when very cold temps freeze the water vapour in the air).

Yes , I have always associated it with the far northern hemisphere.
Wasn't sure if it occurred here due to the suns angle etc.

The so called "green flash" after sunset fascinates me too.

Some activities off the coast?? Whats triggering that ?

Some destabilisation from cold air aloft under an upper trough @Gleno71

If you're wondering what's causing anything, you can usually instantly find your answers if you look at a forecast map (via sites like Windy, Stormcast, or any others of your choosing) of the surface winds and midlevel temps/flow.

27-28th might get something here . Not much if any at all.

Last year here we had late rain but it was the bulk of it in March then April then a break in May then June, July , August, September, October and November right up to the middle of December we had rain every month . Not huge amounts but 40-70mm and no month less than 32mm. I was mowing the lawn every 2 weeks from June right throught to December then with those isolated storms adding nitrogen it was about every 10 days right from December to early May despite it being dryer than normal it must have been the humidity and storm rain. Finally don't have to keep going out to mow the damn lawn ! lol

Unfortunately the new neighbours on the other side got some company Coochie Hydro Green in to fertilise their lawn throughout summer when it didn't need it I think and he's still mowing his lawn every 6 to 7 days it's so thick like carpet.

I stopped fertilising the lawn about 8 years ago and mulch mowed instead when I can . When i fertilised in summer that many years ago I ended up with the lawn going green in 2 days and i was mowing about every 5 days lol. I think they recommend fertilising lawn here more in September.

It's hard to say if the soil has dryed out here as it is sand and it tends to look dry most of the time . I think on the surface it is but if you dig down there is a bit of moisture still from last month .

11.1deg at Yeppoon Esplanade this morning going for a top of 23deg.

So about 2 deg warmer...didn't feel too chilly walking along the beach...wind was lighter....yesterday I saw what looked like steam coming off the lagoon pool as the wind blew. I know the ocean is about 22deg so the pool must be similar.

People mainly in shorts with a warm top or light pants . No one seems to wear jeans here.

I think wind direction apart from that cool spell last week has been Se or east since May doesn't really change much.se day ,light sw or w or nw night and early morning.

Airgram for Brisbane using ICON. Some of the mid to high cloud currently streaming from NW to SE across part of the country as part of the Northwest Cloudband ahead of the upper trough and frontal system still looks like making it here later today or overnight.

It may make for a nice sunrise tomorrow morning but these things are always so hard to predict. If there's just a tiny bit too much high cloud in the wrong spot (near the NE horizon), too little, or too much low cloud there for that matter, it'll ruin everything.

Random question...
Do we experience "sundogs" in Australia?

I'm referring to this...

Certainly do @Rays74, Ive collected dozens over the decades ere on the G-Coast, Iv'e caught plenty of 22* Halos aswell, but very rare to have Halo's and Sundogs at the same time up at these Latitudes in my experiences.
Thought I had a partial Halo and a dog somewhere but not in my existing achives.

GFS and EC deterministic and ensembles have brought back widespread activity across eastern Aus in recent runs after dropping it for quite some time. Looks like upper lows are back at it again with GFS showing two in quick succession.
Amazing, this mornings EC has it all happening out to sea now, followed by cold SWers. Really shows Australia’s weather pattern has now definitely returned to normal. Of course it’s still a long way out so it will keep changing.

The base of the mid/high cloud band, mentioned by Ken yesterday, being illuminated by the ‘ash rise’ on the eastern horizon. This is not the sunrise. Pics taken 50 minutes prior to sunrise.

Looking at the earlier balloon sounding, this Altocumulus would be around 19000ft (5.8km).

Actually gfs I had a look and if it was true completely it looks like Rockhampton and Yeppoon would get their monthly average plus a bit more in 24hrs....60 to 70mm in one day type setup.

Which wouldn't cause any issues up here soil is not saturated

15 deg this morning.
18 deg at Rosslyn Bay...but geez starting off the walk in open area it was a southerly blowing that felt dry and cool.

Should add it is only GFS doing that extreme amount others are between 2 and 20mm for Yeppoon

The dry spell here has now lasted for 10 days, which makes it the longest dry spell since the 16-day dry spell from Oct 2nd to 17th 2020.
The dry spell ends at 15 days here after some light showers this morning brought 1.2mm.

3.6mm for the month to date, which is still in record low territory for June (5.6mm in Jun 1946 being the record low). June rainfall hasn't been in the single digits since 1970.

The next week should be dry. Uncertainty though as to how the month ends at this stage, but still a chance there may be enough rain in the eleventh hour to avoid a record dry / very dry June.

There have also been no thunderdays so far this month. It could potentially be the first thunderless month here since July 2019.

Winter solstice and the camera still won’t focus sorry.
Venus, possibly Mercury, a line of Cumulus giving showers out from Moreton and Stradbroke Islands and the ash glow which started around 5.15am, 1 hour 22 minutes before sunrise.
I keep harping on about it, but still amazed how high the ash is to do this.
This pic taken at 5.33am.

GFS still sticking with pretty much all our months rainfall plus about 30mm extra on top in one day scenario in a week. The average for June is 53mm .


Crazy ....GFS has Yeppoon on 113mm accumulated by next Thursday , GEM has 25.8mm and ACCESS-G 0.3mm

So looking at that either we're going to get a heap of rain way more than usual for June, something more normal like 25mm or next to nothing and just 1-5mm or 0 mm.

I don't know what scenerio will play out , might be just another relativety fine day next week and all the heaviest rain does the avoid Rocky area thing again lol and goes further south .
