Sun will be out within an hour from the looks of it. A surreal way to end of a pretty wild storm day.

The radar itself isn't completely down - just that the data from the scans at certain angles didn't come through (the radar images on public websites is a composite of scans done at various angles to represent a constant height).

Hi Belgarad. Depends where you live. This is going to hang around a bit . I have to say that it was one of the longest STW red warnings images I have ever seen. Must be from Lismore to past Maroochydoore. I am on my phone so I don't know if I can download it and upload it.

Way cold here at the moment. Well these storms were the fastest forming i have seen and looked awesome until they decided to break and go to strathpine. Thundery mess here now and no extreme weather at all at windsor. Incredible radar images before they hit brisbane. But they dropped too much cold air on the inner northside.

Toowoomba top of 21. Satellites suggested general cloud over SEQ, with clear spots towards the coast. Toowoomba had a gust over 100km/h. Cloud didn't seem to stop the storms out at Toowoomba.

For the records:

106km/h wind gust was reported at Toowoomba at 1:20pm

91km/h wind gust was reported at Oakey at 1:10pm

96km/h wind gust at Gatton at 2:01pm

2-3cm hail was reported northeast of Boonah

Golf Ball size hail (~4cm) was reported at Aspley

56mm of rain was recorded at Bundamba (Ipswich area) in 30 minute

42mm of rain was recorded at Mount Tamborine in 15 minutes, 73m within an hour.


Focus now shifts north to SC, WBB and Central QLD where some discrete supercells have fired up.

I have said this numerous times for many years on this forum and others and that is, do not write a storm day off because there is cloud cover about or if we are going to get storms they wont be severe or not as severe because of cloud cover.

Go back over the years and look at my posts. After 50 plus years I learnt that it is a myth. If you have the atmospheric energy needed you will get storms.
I have been in so many now. I have even been in good storms while it has been cold and snowing. My parents came from Scotland and told me but I didn't really believe them until I witnessed them.

Yep, it's also been re-hashed on this forum over and over again smile How much of an effect cloud cover has on storms depends on how much there is, how long it lasts, whether it's patchy thin high cirrus or thicker cloud, how unstable the atmosphere is despite the cloud cover, approaching systems, etc.

To the cloud people, if you read my post i explained how the cloud cleared. You can see in my post this then changed my mind. Move on. It would be a different story if their was a solid cover all day. Thanks smile

Often but not always - refer to this post:

http://forum.weatherzone.com.au/ubbthrea...sto#Post1472220

We've had a number of cases in the past where substantial cloud cover has lasted for much of the daytime and didn't start clearing until around 3pm... at which point, storms suddenly formed on the rear edge of cloudbands and moved across the region.
But this only happens if there's enough instability and/or forcing from synoptic features so is more an exception rather than the norm. Still something that shouldn't be ignored though.

Well, usually I'll be the first one to complain if I miss a good storm but I'm very happy to say we only copped the side of the rain from that big bugger. I actually raced it out of Dalby after reports of hail in Dalby got me moving a bit quicker LOL. I've no idea when I last updated but I can now say we've cracked 182mm for the month!!! C'mon! I'm sure in 8 days we can crack 200mm for October LOL. Strangest month ever. Today was super weird for a storm day.

Discrete is certainly the word! We got a small touch of the top end of the bigger system , only a few mls but nice enough.
But now there are these black rumbling masses to the SW & W of us that don't show on any radar/satellite image yet. I daresay we'll lose the sunset soon to those cells. But I think they will grow & slip South of us.
Best part - too wet to mow , darn shame that!
and on another matter, aww nuffin.... evillaugh

12.8mm here at Wynnum Nth plus max gust 40kph gust at 1520.

As mostly happens this half of the storm season, the TS died before getting here due cool Moreton Bay sea temp. Our better ones occur in late Jan - Feb as the SST is a lot higher locally.

The only times we tend to get big TS's this time of the year are the ones ( not many ) which travel up from the south, as their leading edge still has warmer land temps to keep them going.

Absolute cracker of a storm at Warner.

60mm in short time, with rain rates up around 190mm/hr before it failed.

No power and no internet.

Significant tree damage and full tree defoliationaround cashmere, Warner bray park and Joyner.

I lived at the gap for the gap storm and would find this one today comparable.

Iím not surprised bunya , cashmere , Warner got the best of it. I left Bunnings brendale just before it came and it looked decidedly nasty over that area. I hauled a$$ home to get car under cover. Ended up visually spectacular with the rotation of low lifting cloud . Ended up just perfect here , 40mm. Thereís something about Sunday storms....

Anyone think the stuff coming from the south will reach up here? Quite breezy at times during the height of storm here
