Not exactly SE QLD related...but I wanted to share.

My Astronomy colleague gave me permission to share some pictures of the Sun he took today , optical telescope using special light filters.

Enjoy

Awesome pics @Rays74 ... love it. I've always been curious though, are they from the astronomy section from USQ? I used to study on campus there awhile back and astronomy was also one of my subjects.

On the subject of sun-related things, I saw some nice iridescence in the clouds as the sun was starting to set so I took these pics just before. Not the best examples but was still nice to look at.

No , not USQ.
We are in high school education!
We're very passionate about the weather and astronomy subjects though.

I am somewhat perplexed by the himawari satellite water vapour image in first pic below which is 1800 AEST time today (0800 UTC). I interpret it as showing some moisture above SEQ and to the south west of us.

Second pic below is the EC 00z forecast total precipitable water for the same time - it shows dry air.
Third pic show GFS integrated water vapour transport 00z forecast for 4pm today - it shows not much moisture feed into our region or west of us.

It makes me wonder if the WV image has some bias from cold air, or is showing cold air that may be colder than the forecasts?

That's simply because moisture in mid to upper levels tends to show up a lot better on water vapour imagery than lower down. WV imagery essentially picks up the temps around the tops of layers of moisture so if that moisture's up high like it is now (or there's tall convection), it'll show up really well due to it being cold up there. Even just a limited amount of moisture within a thin layer in the upper levels shows up well.

But because the upper moisture at the moment is only in a thin layer and the rest of the atmospheric column is really dry, it makes little difference to the precipitable water values which apply to the entire atmospheric column or the IVT values which also apply to a big depth of the atmosphere.

That also makes me wonder about emerging technologies for detecting precipitable water at lower levels in real time. I have seen some scientific literature in recent years about processing of GPS signal transmissions
to estimate TPW but I can’t recall reading details of specific strengths and weaknesses of GPS methods at different levels.

If satellite can provide a reasonable estimate of high moisture and other technology could provide reasonable estimates of lower moisture it may provide an opportunity for hybrid weather monitoring technology to be a better source of intelligence?

GPS-RO (radio occultation that affects GPS signals as they pass through the atmosphere and bend) data's already been in use by various models for awhile now including EC and can be used to get info on what the temp and moisture profile's like through the atmosphere. But like many other forms of measurements of meteorological data by satellites, it has its own error margins and uncertainty.

Realtime temp and moisture profile data is also available for viewing as both realtime analyses in the form of soundings and numbers, as well as being routinely fed into models from AMDAR sensors on commercial aircraft as they climb and descend, LIDAR stations which shoot a LIDAR beam vertically upwards through the atmosphere, etc. Wind profilers also detect wind speeds and directions at different heights with some using doppler radar. But a lot of this realtime stuff is only available internally within national weather agencies. Profiler data tends to be more publicly available in the US,.

I see some chat about usa having a brutal winter now Argentina and Brazil just had a freeze.
Is Australia next for a huge cold blast

My thoughts on that in the following link @Tsunami :


Also, as you can see in the above maps, the main focus of the much below-average mean temps in South America so far this winter has been around southern-central parts of the continent with much warmer than normal conditions in northeastern Brazil and Peru. During the US's most recent winter, much of the central and southern parts of the country averaged out to be much colder than normal (in saying that, that amazing arctic freeze that was all over the news was immediately followed by a huge upward swing in temps of up to 20C and more as soon as it was over) while the western US was warmer than normal, as was the extreme northern, northeastern, and southeastern parts).

See 1st image where I've circled the very cold part of South America and the 2nd image of how that fits into the broader context of the southern hemisphere. As I mentioned in the post that above link points to, major cold outbreaks or heatwaves over land tend to attract a lot of headlines but never affect the whole hemisphere and conditions in other areas often get overshadowed.
That's not to say we can rule out continuing cold conditions at other times this winter though.

Tonight the temperature fell steadily while remaining slightly cool. Dew point dropped back from near average to slightly below average while the dew point stabilising in the mid morning before rising slowly during the rest of the morning and afternoon that was close to average before falling slowly from the late afternoon close to average.

Near average relative humidity from the morning that was temporarily slightly below average in the late morning after the relative humidity fell during the morning and became stable until the mid afternoon. From the late afternoon the relative humidity have been slightly above average while rising. Light SSW to SSE winds from the mid morning, S to SE in the early afternoon that became WSW to SE, NNE to ENE in the mid afternoon with some variable winds before mostly calm winds from the late afternoon.

Some frost and fog/mist here this morning. And yep Pete, still on track for a bit of rain moving across later on this week (with some coastal shower activity before that) but as far as southern coastal QLD and northern coastal NSW goes, the partial rainshadowing effect of the ranges, the flattening out of the upper component of the system, and drier air starting to move in post-front while the rain's still falling will probably prevent amounts from becoming too noteworthy. Likely a bit better over the interior west of the ranges though.

Ferny Grove Summary for June 2021. Close to average temperatures and near median rainfall.

The mean minimum temperature was 0.5 C below average, 1 C lower than June 2020 and the lowest for June since 8.6 C in 2018. During the month there were several cool periods that occurred mainly during the middle of the month, accompanied with some warmer nights. The mean maximum temperature was 0.2 C above average and 0.9 C lower than June 2020. Daytime temperatures generally near or slightly above average with some cool days. The mean temperature of 15.8 C was 0.1 C below average and 1 C lower than June 2020.

The mean year to date temperature of 21.5 C was 0.2 C below average and the lowest for January to June since 21.1 C in 2013.

Rainfall was below average with a total of 23.9 mm (38.6% of the long-term average and 121.8% of the long-term median). There was 1 day of thunder with 1 thunderstorm (on the 15th) during the month. The monthly rainfall total was the lowest for June since 22.5 mm in 2014. The highest daily rainfall total of 7.6 mm on 16 June 2021 was the lowest for June since 4.9 mm on 30 June 2015.

After some rainfall at the start of the month, about one-third of the rainfall was measured on the 16th, and another third later in the month. All rainfall during the month was light.


Year to date rainfall until the end of June was 772.8 mm (12 % above average). This is slightly lower than the January to June rainfall total in 2020, which was 786 mm but is higher than 430.1 mm in 2019.

The number of rain days of 74 so far this year until the end of June 2021 was 15 days above the long-term average. This is however the lowest since 61 days in 2017 when compared with January to June rain days in past years.

The long period rainfall totals continued to remain above average for rainfall periods up to 18 month but generally remain near average at the longer time spans, though 36 month remains below average. As compared with May 2021 the 6 monthly rainfall dropped back by 57.7 mm to 96.4 mm above average, 9 month rainfall dropped back by 15.1 mm to 94.9 mm and 12 monthly slipped by 20.5 mm to 75.6 mm above average. 18 month rainfall remains above average at 191.3 mm after slipping by 25.7 mm. 24 month rainfall slipped slightly by 18 mm from 9.8 mm above average to 8.1 mm below average. 36 month rainfall continues to remain the only period that is significantly below average that was 150.6 mm below average but improved by 14.4 mm from May 2021. 48 monthly rainfall slipped slightly from 2.2 mm above average to 23.4 mm above average.

The largest positive anomaly was observed by the 18 month rainfall that is the highest since 199.8 mm above average in the 18 months to June 2016. The lowest anomaly that was observed by the 36-month rainfall was the lowest for June since 263.3 mm in the 36 months to June 2016. Compared with the same period in 2020 the long period rainfall totals have improved or dropped slightly. The greatest increase in the long period rainfall anomalies was the 18 month rainfall that have increased by 523.3 mm.

Models again showing some rain for Friday? @WarwickEye2Sky would probably be best placed to give you the report, but a lot of farmers need some dryer weather for a while around Warwick. Speaking to a bloke on Friday who couldn't get into his paddock to plant his onions!! The Condamine was definitely up yesterday.
Quart Pot Creek was swollen. Great to go to sleep with the sound of it running. Neg 1.1 min at my place this morning.
IMG_5697.jpg
Great pic Sandbank. Yes, I have heard that from several people here that we need to dry out a bit. Even firewood is in short supply as the paddocks are too wet to access the wood. Looks like 10-20mm here for Friday. After that, we may get a couple of weeks to dry out as it looks like we will be in mostly a zonal flow. I think Ken might have alluded to this a short time ago.

Been getting some drizzly showers here.

1st image - Multimodel wind gusts for Brisbane over the next few days. The W to SW flow could become quite gusty at times by the middle of the day on Saturday but how strong will depend on how the behaviour of the low that’s expected to form and rapidly intensify off the NSW coast.
2nd image – EC/GFS/ICON consensus map for greater than 25mm of rainfall within the next 5 days.
3rd image – GEFS probability of precip map for Friday (between 4am Fri and 4am Sat in this case due to datafeed problems with the 3-hourly data).
4th image – GFS accumulating rainfall amounts for 5 x 5 gridpoints (total of 25) within a box surrounding Brisbane, lagged over the past 4 runs. This equates to a total of 100 individual forecasts in that area for the next couple of days.
5th image – EC precip and wind animation.

looks like Sydney might cop a hammering - keep everybody indoors?

17 minimum here tonight/morning then 48 hrs later 9 deg minimum then by the end of next week climbing past the 12 deg average to the mid teens , why can't it be consistent like summer when it's always 20 something every night lol .

More humidity here today, mowed the lawn and my sunglasses fogged up .

Lawn was slowing down growth until last month . Hopefully i won't have to mow in the next few months being dryer and temps warming from September.

I have been aware of the term north west cloud band for several years, and it being the probably the more common form of atmospheric river for Australia. They typically help rainfall in southern areas and not consistent for our region. But in the last year or so I have observed their orientation coming more up our way.
Check out the orientation of this GFS forecast moisture feed (IVT) for about a week away.
if this sort thing happens more often they may need to form a new term “west cloud band”

That's very interesting to see
Great to see moisture and weather systems traversing across very dry regions of Australia.
Seems to have good tropical in-feed.

Anyone else noticed that for 3 weeks in a row it has rained on a Friday in SE QLD?
Good to see semi regular rain now regardless.
