Hi guys,

Nice to see the other isolated supercell covered as well.

Awesome stuff!

Hi gus,

This is the approaching supercell at Booral. The video is 5x and there was possible weak real time rotation evident as seen in this video and it caught our eyes:

Dungog supercell November 2 2010

There is a possible slot and the possibility of rotation in that region. Any other thoughts? Consider we are lookign directly west and the storm is oriented SE meaning this is the region where such features may originate - perhaps under a second updraft - not sure.

Edit: I have kept looking at the video several times and I am not convinced (or I have sore eyes). Inconclusive to me.

Good work guys! Like the inflow tail into that cell!  Pity you and Nick/Jimmy all had a rough go when it came to visibility, roads and terrain - I can certainly sympathise.  I was wondering what terrain you would've been dealing with and hoping you could get some structure shots. Thanks.

Brad.

Brad,

Just ensuring you know these were two separate supercells.

Pintang, that is a nice beaver tail - great catch! What orientation are we looking at - are you looking from the eastern side?

I would not be harsh on yourself, you have the best strucutre picture of the day imo.

Shane, I was definitely wandering what was in that persistent cell - good hail size! Was the atmosphere cool for the hail to remain so large for such a reasonable period of time?

Regards,

Thanks Jimmy - I think the cool temps and accumulation of the hail helped it to stick around for a good time after it had fallen, I was surprised at the average size of hail still over 2cm when I got there so late. The amount of hail that fell must have been incredible.

Hey Jimmy.

I was on the Southeastern side of that storm. My photo of the Beaver Tail was taken at exactly 1:13pm roughly 10kms E/NE of Gloucester. Have another look at the radar loops below( i've posted another link below) . The storm was looking rather nasty on the radar north of Gloucester between 1:10pm and 1:30pm.

When the lightning barrage starts towards the end of my video you will notice a large inflow band feeding into the storm from left of screen to right ( or from South to North!) This footage was taken at 2:20pm, 20kms E/NE of Gloucester. This inflow was feeding into that very large storm on the top edge of the Newcastle radar( which was a completely seperate supercell to the one I witnessed an hour earlier!) This is actually the storm that developed just south of Mt Seaview(you'll need to open the Newcastle 256km to see what I mean)

I had a look at googlemaps today,and there was a single road option that would've taken me quite close to the first storm.Unfortunately the road followed a valley for much of its duration but offered the occasional view. Its unfortunate I couldn't find this road, but its not suprising given I was totally familiar with the area.

Excellent shots/footage guys. A very good low vis set-up ( ), warm front eastern US style! The loop that I looked at yesterday sported several likely supercells, matching up with your video Pingtang, Jimmy. Jimmy, that looks RFD 'intrusion' in your clip - look at the motion --interesting.  

I'm not totally surprised that there are no reports of very large / giant hail, which can be quite limited in areal extent, although Gresford however seemed to be right in the firing line of the southern storm when it was cranking. The extent of stripped leaf-litter in Shane's pic certainly suggests that at least large hail and possibly in combination with strong winds too.

[Jimmy Deguara]

Hi Pintang,

So you wre onto the beast! I stand corrected. Now that makes sense as I suspected the cell south of Gloucester was elevated.

We attempted to get this storm and you may have noted the side anvil pictures amongst the crap low cloud!



Pintang, are you certain that is an inflow band? At 30 seconds, the feature looks like a "beaver tail" structure. Given the orientation and E-NE winds flowing in and the feature say directed SE even E, you may have a "beaver tail". Regardless of this, well done!

Oh well - all significant storms were covered on the day!

Brad,

Just ensuring you know these were two separate supercells.

yeah thanks Jimmy I know they were seperate, just drawing parallels with the problems you and Pingtang both had getting onto them.
