Where are all the good weather web cams these days? Someone used to maintain a great site with storm spotting web cams scattered in SEQ, but I think its gone.

This one is nice and has history, but looking north from Southbank. Can see convection off in distance early AM in a couple frames which is the stuff over sunshine coast probably. Just the barest hint of some instability in the mid level deck, but hard to say whether that is only something I'm seeing in hindsight.
Hi Michael,

There are still a few decent web cams around. I like the ones at the airport as they tend to include some sky in them for the information of pilots intending to use the airport. Most of these seems to be working although there are obviously occasions when things go wrong.
My webcams

https://mywebcams.com.au/
(The old Chapel Hill Web cam that was on BSCH is now here with some views to the SW and W also has a 24 hour time lapse.)

Also a number of cameras at places like Boonah, Gatton and Murwillumbah which come in handy.

Skycam Network
Also a web site featuring airports.
https://www.skycam.net.au/main/index.html

Good for those days when Roma or Charleville might be getting a storm.

Of course BOM and Air Services Australia. I don’t have much of a view to the S & SW so Toowoomba, Archerfield and the Gold Coast come in handy.

There are a couple of smaller airports on the Darling Down that also have web cams some good.

There are also a few private web cams around, if you use weather underground you can also add a layer to search private weather stations that have an associated web cam.

Cleveland web cam: https://www.clevelandweather.net/webcam/default.php

Since the 2011 floods a lot of councils have installed flood cameras on some creek crossing or areas that flood. The cameras are usually located in the Disaster Management pages of their respective web site. Two that I look at occasionally:

Somerset Council 9 Cameras https://eservices.somerset.qld.gov.au/floodcams/

Lockyer Valley 13 cameras https://disaster.lvrc.qld.gov.au/

Logan City Council: https://disaster.logan.qld.gov.au/


And back to today just over 14 mm from this morning's storm some cracking lightning and house shaking thunder, a tiny bit of hail mixed up in the rain.

Near average temperature in the morning stopped rising with the thunderstorm, which after being stable for a few minutes then fell a little with the thunderstorm and became cool. The temperature rose later in the morning, more quickly following the rain before reaching the maximum temperature in the mid afternoon while easing to near average from the early afternoon. The temperature was a little variable in the afternoon and have remained near average during tonight. Rising dew point during the morning stopped rising in the mid morning becoming slightly above average in the mid morning, fell a little with the thunderstorm while easing back to near average before rising later in the morning slightly above average. Dew point rose slowly in the afternoon and became moderately high and then fell from later in the afternoon slightly above average becoming near average from early tonight before falling more slowly later tonight.

Relative humidity was stable until the mid morning and became moderately high, started to temporarily fall before the mid morning thunderstorm before rising with and following the thunderstorm and became very high. From the middle of the day the relative humidity fell slowly easing to moderately high in the mid to late afternoon, before starting to rise later in the afternoon and eased to slightly above average tonight and to near average later tonight while rising slowly. Calm winds until just before the mid morning thunderstorm with W to SW winds before and with the thunderstorm with some S to SW winds, then calm winds with the rain following the thunderstorm before E to ESE winds tended SSW to SSE later in the morning with some calm winds. In the afternoon winds backed from SSW to SSE to SE to NE in the mid afternoon before veering during the rest of the afternoon to N to WNW in the late afternoon. Tonight the wind have been calm with some W to NW winds.

Thick fog still shrouding my area (1st image above) and many others in SEQ. I also saved a cool view from the Emporium Hotel webcam from earlier this morning (2nd image) of the developing fog starting to drape over some of the buildings in the CBD.
Current visibility at Brisbane Airport is still 400m while at RAAF Amberley, it’s only 100m.

A road weather alert's also in effect for Brisbane due to the fog causing hazardous driving conditions:
" Road Weather Alert for Brisbane
Issued at 5:47 am EST on Wednesday 16 June 2021.
Reduced visibility in fog will make road conditions dangerous during Wednesday morning in the Brisbane Area. "


The next cold front's about to sweep across........ but even though it’ll be accompanied by a band of showers, patchy rain areas and local thunder approaching the region tonight/early Thursday, totals for SEQ still look on track to be low, and some of the unluckier places may even hardly get anything at all. Some places on and west of the ranges may fare a little bit better (and should get this rainfall earlier) but high totals don't look likely there either for the most part.
Gusty colder westerlies then invade the area behind the front and may even become strong on Fri/Sat.

Images 1 to 3 above - Sequence of fog images from the Emporium Hotel webcam this morning. One of my faves is that first shot where you can see a small hat of fog over the top of one of the buildings as the flow's forced to rise a little bit when it hits the building. Amberley's still cloaked in fog as I write this (10:30am) with 800m visibility.
Image 4 - Detected lightning in the 48hrs to this morning.
Image 5 - EC ensemble meteogram for Brisbane. I've circled the items of interest i.e. the very gusty westerlies and drop in temps.
Image 6 - The next cold front sweeping through. EC precip and winds. Can never tell with absolute certainty whether frontal bands suddenly intensify a little approaching the coast or continue to weaken after they come off the ranges, nor whether they arrive earlier than expected or not. But for now at least, still only expecting low totals east of the ranges here with some of the stuff coming through at night or early tomorrow morning. Brisbane ended up with 14mm yesterday. Two rounds of storms yesterday in the region with very close lightning strikes locally, some hail, cold rain, a double rainbow, nice sunset, then fog that took ages to clear... good winter fun.

That'd be a nice example of altocumulus Rays. It's streaming off the inland band of cloud and storms associated with the approaching front and upper trough. And yeah WarwickEye2Sky, appears to be another front and low moving across in about a week or so's time as well (GFS also tries to develop another low near the coast) but will have to wait a bit longer for a clearer picture.

Above is a precip/winds loop from Meteoearth from this arvo til tomorrow arvo that shows the approaching front. As far as SEQ goes, still looking at low rainfall totals east of the ranges, mainly late night/early morning, although for any luckier spots that manage to get a gusty overnight storm, totals might be boosted a bit on a local scale.
Probably won't feel that much colder until Friday though (unless you're in the shade and exposed to the breeze) since the winds immediately behind the front have a long westerly fetch.

It's an interesting situation indeed @Vinny
The Esplanade site used to have an electronic wet bulb probe (if the muslin wick covering their bottom dries out because the the resevoir it's dipped in isn't topped up by the observer, it'll read the same temp as the dry bulb temp probe and therefore the RH will read 100%). But it looks like it was replaced with an electronic humidity probe in 2016 so if the RH readings are wrong, it could be a fault with the probe itself.
Thing is though, nearby stations such as Samuel Hill and even Rocky have also been showing RH values close to 100% for quite awhile now too.

In other news, latest scenario from EC above - still tries to sweep yet another big cold front and low towards us in about a week's time.

Well it was grey and foggy yesterday and then spitting most of yesterday. I see tomorrow afternoon a return to low humidity.

Seems the station is back up again... humidity at 90 percent

Just looking further north is that normal for Townsville says 28.5 deg feels like 31.9 deg dp 23.4 deg in winter !! ??
Our minimums the last 2 mornings here in Townsville have been 23 & 22 with plenty of humidity Vinny. The last couple of days have felt summerish. Hopefully back to Winter tomorrow. Heard on the radio that the 23 minimum was the hottest June minimum for a long time.

The gusty westerlies over the next few days still look like they could become pretty strong at times on Saturday later in the morning and afternoon as the Tasman Sea low cranks.
Not looking at any kind of widespread destructive wind event but the peak gusts that day might get close to the strengths where some downed branches here and there, or brief power interruptions start becoming a chance in some pockets of SEQ.
Also still looking like the colder air will be felt more tomorrow and Saturday due to a more SW component to the winds during the early part of their journey towards us.

Still signs of yet another frontal system and big low marching across from the west although I’m not normally a big fan of our chances of getting high rainfall amounts from them (since many of them which look impressive while they’re still near SA often tend to peak too far west then start sliding southeast, leaving us with dregs). But if we’re lucky, the front could still try and bring a band of showers, rain areas and some embedded thunderstorm activity here towards the end of next week. Either way though, it’s still too early to tell for sure anyway.

The temperature remained warm during the rest of the morning, before easing back to slightly warm during the afternoon as the temperature stabilised in the early afternoon before falling from the mid afternoon. After falling the temperature rose a little during tonight before resuming the fall in the temperature during the rest of tonight, after becoming warm.Dew point fell in the morning and afternoon easing to near average from the mid morning, slightly below average in the early afternoon and moderately low in the mid afternoon. From later in the afternoon the dew point became generally stable while remaining moderately low.

As the relative humidity fell in the morning and afternoon it eased form slightly below average in the morning to moderately low from the late morning and to low from the late afternoon. After rising from later in the afternoon the relative humidity fell a little before rising slowly and became very low. Light W to WSW winds in the morning with some SW winds, WNW to WSW in the afternoon and during tonight with some variable winds and calm winds at times.

Our minimums the last 2 mornings here in Townsville have been 23 & 22 with plenty of humidity Vinny. The last couple of days have felt summerish. Hopefully back to Winter tomorrow. Heard on the radio that the 23 minimum was the hottest June minimum for a long time.

Back to low humidity now up until about Tuesday.

I was watching a live Youtube channel a guyu from Brisbane he was saying they had bought a humidifier to put moisture back in the air because the air is so dry in Brisbane in winter.

Indeed @Vinny
More-so towards late winter compared to earlier in winter. Except when we get some rain of course. In saying that, it often gets much drier further north of SEQ (but outside the deep tropics) when we get a vigorous west or southwesterly flow behind a change. The average 3pm relative humidity in Brisbane in June is 52% and for August, it's 43%...... while for 9am, it's 72% and 68% respectively.

Speaking of rainfall, above is the latest multimodel plume for Brisbane.

Interesting. The SAM is well positive and yet we still get constant westerlies. Seems the pattern is doing its old trick of huge cut-off upper lows moving across southern Australia at a screaming pace and then come to a screeching halt over the SW Tasman and bombing a massive slow-moving Southern Tasman Low, with the highs under this. Then the SAM is supposed to go negative later on. This possibly should go in the Climate Driver Thread but it goes very quiet sometimes.

I have a random question of the day.

Is is possible for a Warm Front to pass over SE QLD?

Has this ever happened , if so what causes it?

I notice Warm Fronts barely show on synoptic charts , maybe during a deep low in the Tasman Sea.

Would it more likely occur during Winter or change of seasons?

Apologies for my curiousity.

Yes and yes @Rays74
Warm fronts have sometimes passed through SEQ but they're not very common. The thing to remember here is that the MSLP charts you see on the Bureau's website have been traditionally been done by the Bureau's National Meteorological and Oceanographic Centre located at head office in Melbourne. And they've always been notorious in weather circles for their reluctance to draw in fronts, especially warm fronts, even when there's clear evidence of their presence (horizontal and vertical temp gradients, obs, characteristic cloud patterns, etc). It's been a pet hate of mine and some others I know. In fact, you could pretty much safely ignore them as far as identifying whether there's a warm front somewhere or not.
You'll often see warm fronts and occluded fronts marked on charts from many other national weather agencies which cover this area such as the NZ Met Service (although they do tend to overdo it a bit), NOAA's central Pacific branch, etc.

In general, large warm fronts tend to be more common during northern hemisphere winters, especially in the US where it's common to get a warm moist airmass coming up from the Gulf and overrunning a mass of very cold air that's been sitting over the interior. In the southern hemisphere, they're a bit less common but they tend to affect the Southern Ocean more than Australia... although on occasion, they can also affect TAS and VIC.
When warm fronts occur here in SEQ (which are hardly ever marked on the standard MSLP charts), they tend to be on a smaller scale and typically occur when a front/coastal change that's just passed through lags back onto the coast and starts curling around as a localised area of low pressure starts to form on its tip. This can also be in conjunction with an east coast low or a subtropical low that manages to wander just inland of the coast. You'll then sometimes see a frontal structure start to develop from it with a small warm front structure extending out to its east. This front then usually pushes south along the coast as the warm moist air being drawn down the eastern flank of the low runs into the cooler air to the south. When this happens, it's usually only the coastal fringe that gets affected by the front. It looks quite obvious on satpics, obs, and model maps, and as the warm front pushes south, you'll see winds suddenly shift from cool E or SE'lies around to warmer N or NE'ies and a sudden temp rise, sometimes even against the diurnal trend.

The first bunch of images above are some examples of warm fronts that have occurred in the Tasman Sea and the Southern Ocean using EC winds, temps and precip.

The last animation above is a less common example of one a few years ago that occurred in SEQ. This one involved a more localised disturbance near the coast which then extended a warm front out to its east - this subsequently pushed down the coast with an accompanying temp rise and wind shift in the obs at the locations it passed over.

Excellent information Ken
I really appreciate the response.
Those graphics and animation really help me understand the warm front process.

Another question , is it possible for fronts to move from a East to West direction , or a North to South direction?

I understand most of our weather systems originate from the West or South of us , unless it's a tropical or monsoon system.

Can fronts have the same behaviour as a trough system? for example can they travel in a westerly direction?

Thanks so much

Troughs can behave similarly to fronts if the trough is basically an extension of a front i.e. there's somewhat of a temp difference on either side of the trough. But your typical inland trough in the deep summer months is a bit different because they're often pseudo stationary and periodically advance eastwards then retreat westwards again in response to synoptic systems further south and how much inland heating's taking place.

Re fronts, east to west movements are possible but it's uncommon with a warm front and even rarer with a cold front. It's more common with occluded fronts with well-matured cutoff lows where the cold front starts leaning over towards the southeast a lot (negatively tilted), meets up with the warm front, and the resulting occluded front curls right around the low. In these cases, the occluded front can push westwards (on the southern and western flank of the low) especially if the low's moving south or southwest.

A cold front moving directly northward is a bit less rare but still not that common either (northeastward moving cold fronts are much more common). When a northward moving cold front occurs, it's often the last in a series of fronts pivoting up and around an area of deep low pressure passing across to the south of the continent. But when it does occur, the air behind it can be exceptionally cold because of the very southerly fetch behind it.
In contrast, southward moving warm fronts are more the norm than the exception in the southern hemisphere (when warm fronts do occur). The typical scenario involves a warm front extending east out of a low and that front pushing southwards as the warmer northerlies run down the eastern flank of the low.

I've added a few more examples of some past warm fronts in our latitudes. Unfortunately the animation doesn't show the temp contrast pre/post front too well since the colour gradient scale I used back then in Windy was different but you can see those northerlies pushing down into the easterlies and slowly invading the area. It was a lot more noticeable in the temp/wind obs from the AWS's.
