A short sharp shower last night about 9pm; and another about 2:30pm today enough to wet the road. Last nights didn't even show on the radar... If the wind is SE, this place just makes rain. Not sure how much though as my weather station is down, probably .5mm. I had best fix that this week!

Sooo many toads were out last night, I thought they must have known the shower was coming and maybe they did... But heaps of winged termites were still flying this morning so perhaps the toads were just out for a feast.

Yep Ken, it is very hard to distinguish weather related animal antics from seasonal happenings as seasons drive weather.

Hmmm... the synoptic charts... Does anyone want to extend the new thread.?

We've had storm birds for the past week here; had a break over the weekend but started again Monday afternoon. (Do they work a standard week???)
But all the signs are building up nicely to see some storms pretty soon I think.

Yeah I pretty much ignore the ants now, but the frogs and spiders are pretty good indicators. The ground spiders start heading for shelter before rain I've noticed out on our farm.

I'm a little skeptical that something with a brain the size of a spiders or an ants can predict synoptic scale weather patterns days in advance.

They can detect changes in barometric pressure and together with their highly complicated brain structures , are able to plot CAPE values and wind shear, days, sometimes weeks in advance

haha I think when a rain drop is 3 times the size of you... ya have to be prepared, they like to be well prepared shifting the 100 million eggs that keep thier population going. I think they see signs or also indicators of rain coming just as we do by looking at the sky and gfs feeling the humidity in the air and other indicating insects and animals and so on....

Bwahahahaha, SteveO, makes you look at it a bit differently hey. On our property we have these little hairy ground spiders that live in holes in the ground, obviously in a good rain they drown and we often get them in the house prior to rain. Of course I have only seen 2 of these, the other 5 or so were different breeds (though not house spiders) so it gets me wondering as generally we just don't see them.

It's so sad how dry and crispy the so-called grass has gone in the last week and a half of hot weather, it looks like mid-summer already frown very depressing.

And as for Tuesday, all I can say is 'what could have been' since the models now have the surface trough pushing well out to sea by the late morning, and the cold pool sweeping across quite early as well. Still can't rule out something overnight Monday / early Tuesday morning though.

Looks like instability might start increasing again later this month as per the below graph:

Plunged back into winter here today, had a light frost thismorning on 2C and is now 1:30pm and the temp has still not risen above 21C. Feels freezing after weeks of 27-30 C temperatures! Amazing stuff for mid-October.

Saw a VERY nice funnel and a shot lived waterspout off the Gold Coast today - it would have been around 10:30-11am I guess... I was quite a ways inland (Ashmore) so too far for photos. I was on the 3rd level of a building so could see well above the tree line so you would have otherwise needed to be on the beach to see it I'd say. I couldn't quite see the ocean but the funnel was so long at one point there's no way it wouldn't have been connected to the ocean. The parent congestus cloud was a beauty too - thunderstorm strength updrafts but the instability was very shallow so they weren't able to grown to great heights/mature into a storm.

Great stuff Ben, I would love to see a waterspout up close on the beach or on a boat/jetski it would be fascinating. I noticed the congestus cloud this morning and wondered why the clouds did not get to much height thanks for the explanation.
I just was checking the webcam off Victoria Point and just got a link for the time frame 5am to 11am.

Actually that camera captured a great example of how powerful the convection was off the the Gold Coast this morning - on the far left of this sequence you can see some updrafts boiling away. Really, they are severe storm strength updrafts... they're just restricted by the stability above the very shallow unstable layer in the lowest couple of km's

So the stable air above is warmer than below the cloud tops? Is this also a good example of an inversion?

Technically an inversion is a layer of air where the temperature increases with height - today that wasn't *quite* the case as you can see in the sounding below - the air temperature between 750mb and 650mb doesn't increase with height, it's almost constant with height which would make it more of an isothermal layer - but the effect is the same as an inversion... air rising up into it from the surface encounters surroundings that are warmer than itself and it loses it's buoyancy.

This is a high resolution ACCESS-R sounding for roughly the time and the location that I saw the strong convection and the funnel/short lived spout. I realise that you don't need these things annotated Steve but I've done so for general interest. Some might laugh at 150 CAPE being labelled as strong but it's all relative to the area that the CAPE is encapsulated in. 150 CAPE on a storm day when the instability extends over 8-12km... that's weak CAPE. 150 CAPE that's encapsulated in a tiny 2km of the lower atmosphere - I would suggest that's strong CAPE. Also, the cloud top is a boxed area as the upward motion of the updraft doesn't always instantly stop once it encounters the stable layer above it, it will 'overshoot' into that stable layer just as a strong thunderstorm updraft will.
